I.General InformationA) ObjectiveTo provide an opportunity for engineering students to demonstrate applica on of soundengineering principles toward the development of prac cal, efficient, and sustainablehuman-powered vehicles.B) Superiority of RulesThese rules have been established by ASME’s Human Powered Vehicle Challenge (HPVC)Commi ee. Should any conflict arise between these rules and those of the ASME, the ASMErules shall dominate. Should any conflict arise between these rules and other informa onregarding the ASME HPVC, whether generated by the ASME or any other organiza on, theserules shall dominate.C) Questions and Comments About the RulesQues ons about the rules must be posted on the HPVC Ques on Forum listed below (sec on1.D).D) Location and Competition InformationLoca ons of all compe ons can be found on the official HPVC website. Teams wishing topar cipate should consult the HPVC website, ASME HPVC Community on Facebook, and HPVCQues ons Forum.Official HPVC Website: h ps://community.asme.org/hpvc/default.aspxOfficial Rules and Forms: h ps://community.asme.org/hpvc/m/default.aspxHPVC Facebook Community: h p://www.facebook.com/ASMEHPVCHPVC Ques on Forum: h ps://groups.google.com/forum/#!forum/asme-hpvcE) Schedule Summary & Host InformationThe ASME HPVC website shall specify all the important dates and contact informa on for therelevant compe on.The following is required for par cipa on in the ASME Human Powered Vehicle Challenge.

Scores from each event are totaled to obtain the overall score to determine the winner.G) On-Site RegistrationOn-site registra on begins on the first day (typically on Friday morning) of the compe on. Allteams and riders must check-in (in person) before the end of the registra on period to receivetheir vehicle numbers and wrist band (required to be eligible as a rider).2019 HPVC RulesSeptember 23, 2018Page 8 of 55

II.General Rules of CompetitionA) Minimum Number of Vehicles to CompeteThere is no requirement for a minimum number of vehicles. However, should the number ofvehicles entered be more than one but less than four, the number of awards granted for overallplacement in that event shall be one less than the number of compe ng vehicles.B) Events of the Competition Design Event: Teams are scored on their applica on of sound engineering principles andprac ces toward a vehicle design. This event includes a wri en report, a technicalpresenta on, performance safety video and sta c judging of their HPV. Men’s and Women’s Speed Event: Teams are scored on the speed of their vehicles, eitherin a flying start 100 meter sprint or a head-to-head drag race from a standing start. TheASME HPVC Commi ee will announce which event will be held well in advance of thecompe on. Separate scores for men and women are recorded for this event. Endurance Event: Teams are scored on speed, prac cality, performance and reliability oftheir vehicles in a road race format with urban transporta on obstacles and challenges.C) Modification of VehiclesModifica ons to the vehicle are allowed between events, as long as safety is not compromised.Vehicles must retain their main frame and general drivetrain configura on. Any vehicle deemedto have undergone changes in excess of this allowance will be permi ed to compete if it doesnot present a safety risk; however, any scores achieved will not be credited to the original entry.D) Aerodynamic DevicesVehicles may include components, devices, or systems engineered specifically to reduceaerodynamic drag. Front fairings, tail sec ons, full fairings and other such devices areencouraged. The effec veness of aerodynamic devices must be substan ated in the designreport in order to receive credit for the design scores regarding aerodynamics.Makeshi devices which are unrepresenta ve of the design, are crudely cra ed, and/or presenta clear safety concern will be prohibited, and must be removed prior to racing unless previouslygranted a waiver by the Head Judge. Fairing configura ons may be changed between events inaccordance with Sec on II.C provided that all safety requirements, including the seat belt andRollover Protec on System (RPS) rules, are not compromised by the change of configura on.E) Vehicle Number and LogosASME will assign each vehicle a number. The number "1" will be assigned to the overall winnerfrom the prior year's compe on. All other numbers will be assigned by ASME. At its discre on,ASME HPVC Commi ee may consider requests for specific vehicle numbers, but no zero or tripledigit numbers will be allowed. Requests can be made by sending an email tohpvcasme@gmail.comDecals – ASME will provide two adhesive decals to each team during the on-site registra onprocess. Each decal will display the assigned vehicle number as well as the ASME logo. Eachvehicle shall provide sufficient space on either side for these s ckers. This space may includefairings, cargo containers, or surfaces especially designed for this purpose. The decals shall be nolarger than 35 cm wide x 30 cm high. If one or both of the ASME decals are lost, obscured, ordifficult to see from either side of the vehicle, the vehicle shall be removed from the compe on2019 HPVC RulesSeptember 23, 2018Page 9 of 55

un l they are restored. If a vehicle number is obscured during an endurance race, any laps runwithout a visible number will not be counted.School Name – All vehicles should display their school name or ini als on each side of the vehiclein characters at least 10 cm high in a color that contrasts with the background.F) Fairness of CompetitionAll par cipa ng teams will be assured an equal opportunity and a fair compe on. Anypar cipa ng team that, in the reasoned opinion of the judges, seeks to exert an unfair advantageover other compe tors will be subject to a penalty in performance points or disqualifica onfrom the compe on.G) ProtestsProtests must be announced to a member of the judging staff either at the me of the incidentor within a 15 minute period following the announcement of results of the event. Following theannouncement of the intent to protest, a wri en protest must be presented within 30 minutesunless otherwise allowed by the Head Judge. Oral protests will not be recognized. Protest Formis available in the appendices.Protests must be specific in nature and must include a factual account of the event beingprotested and the specific rules infrac on, or the perceived error in the scoring of an event.ASME HPVC Protests Form may be used to file a protest. This form is available in the appendix ofthese rules. Protests will be examined and resolved by the judges at their earliest convenienceduring the compe on. Their decision will be final and without further appeal.H) Event ScoringScoring for each event and the overall scores will be based on a points system. The team with themost points wins the event.I) Energy Storage DevicesVehicles may employ the use of energy storage devices for purposes of accelera ng andimproving performance of their HPVs, but by no means are they required. If energy storage isused energy must be stored a er the race has begun with human power as the sole externalsource of energy. Prior to each race, each team must demonstrate that their storage device haszero propulsive energy stored.During the safety inspec on the team must be prepared to discuss the safety of the storagedevice, especially during a high-speed incident. Teams whose vehicles present an unacceptablerisk in the percep on of the judges will not be allowed to u lize the energy storage device in thecompe on.Stored energy used to power non-mo ve systems (does not impart momentum to the vehicle) isallowed and may be stored prior to the beginning of the race.Combus on engines are excluded from the compe2019 HPVC Ruleson.September 23, 2018Page 10 of 55

J) Report and Video PublicationA er the comple on of the events for a par cular HPVC, all design reports and submi ed videoswill be published to a shared website.If a team does not want their design report and/or video posted publicly, the team must submita request, in wri ng, to the event Head Judge no later than the submission deadline. The requestmust convincingly outline the grounds (such as ac ve NDAs, or submission for intellectualproperty) for which the request is being made, and teams must be prepared to present analterna ve submission omi ng any specific sec ons in ques on. Requests will be granted ordenied by the judging commi ee, and their decision will be final and without appeal.K) Design FeedbackIn an effort to help teams learn from their experience the judging staff will be providing feedbackon each team’s performance in the Design event.During the evalua on of the Design reports and live presenta ons the judges will take note ofspecific areas where teams may be able to most improve their scores. Judges will be looking forthings like areas that may be missing key details, where teams missed the mark with informa onprovided or just generally in what areas team can improve the most. Feedback provided will beconstruc ve and ac onable so that teams will walk away with a be er understanding of thescores they received and how they can improve their skills further.Feedback will be collected in a standard wri en format and delivered to the team captain a erthe conclusion of the compe on.Note: No ac on is required from teams to receive feedback outlined here, this sec on is simplyincluded in the rules as informa onal.L) Readiness to CompeteTeams must show up ready to compete and repair facili es will only be provided if the hostoffers. The host is not responsible for assistance with vehicle repairs. All vehicles must arrive atthe compe on ready to ride and pass safety inspec on.2019 HPVC RulesSeptember 23, 2018Page 11 of 55

III.SafetyA) GeneralThe safety of par cipants, spectators, and the general public will override all otherconsidera ons during the compe on. The judges will consider the safety features of thecompe on courses, as well as those of the compe ng vehicles, in permi ng each event of thecompe on to begin or con nue. Any event of the compe on may be delayed, terminatedprematurely, or canceled if the Head Judge, in consulta on with ASME and the Judging Team,determines that such ac on is necessary in the interest of safety.B) Performance Safety RequirementsEach vehicle must demonstrate that it can come to a stop from a speed of 25 km/hr in a distanceof 6.0 m (19.7 ), can turn within an 8.0 m radius (26.2 ), and demonstrate stability by travelingfor 30 m (98.4 ) in a straight line at a speed of 5 to 8 km/hr (fast paced walking speed).C) Minimum Braking System RequirementEach vehicle must have a braking system with properly designed brakes on the front most wheelof the vehicle at a minimum. If mul ple forward wheels are employed (such as in a tadpole trikeor quad bicycle design) each wheel must have its own brake. Simply put, vehicles must at leasthave front brakes.Even though teams may employ front brakes outlined here teams are s ll responsible to conductadequate tes ng to ensure that the vehicle can pass the stopping performance test outlined inthe performance safety requirements.D) Rollover Protection SystemAll vehicles must include a rollover protec on system (RPS) that protects all drivers in the vehiclein the event of an accident. Func onally, the RPS must: Absorb sufficient energy in a severe accident to minimize risk of injury Prevent significant body contact with the ground in the event of a fall (vehicle movesfrom upright to res ng on its side) or rollover (vehicle moves from upright to an invertedposi on) Provide adequate abrasion resistance to protect against sliding across the ground. This ispar cularly important around the rider’s arms and legs. Adequate guarding must beincludedThe RPS must allow for a load path suppor ng the driver and retaining them from being ejectedfrom the HPV in the event of a crash. This load path will be defined from the ground (impactpoint), to the outside of the vehicle body, through the structural RPS, through the safety harness,to the driver’s body (center of gravity). A thorough RPS design includes the structural for tude ofnot only the roll bar/frame, but also a rigidly mounted and structurally sound seat and properlyaffixed safety harness. In the RPS analysis teams must document the load path from rider toground to receive full points.In order to demonstrate the effec veness of the RPS in protec ng body contact from the groundteams may be required, during safety check, to lay their vehicle on its side as well as invert itfully with the largest rider inside. Once laying on its side and inverted the rider must not makecontact with the ground and if safety is compromised vehicle modifica ons will be required orvehicle will not be allowed to race.2019 HPVC RulesSeptember 23, 2018Page 12 of 55

The RPS must fully protect the driver in a con nuously hoop, a three point design does not meetthis requirement. In addi on, the RPS shall meet the top and side load requirements describedbelow.1) RPS Load CasesThe RPS system shall be evaluated based on two specific load cases – a top load represen ngan accident involving an inverted vehicle and a side load represen ng a vehicle fallen on itsside. In all cases the applied load shall be reacted by constraints at the safety harnessattachment points; simula ng the reac on force exerted by the rider in a crash.(a) Top Load: A load of 2670 N per driver/stoker shall be applied to the top of the roll bar(s),directed downward and a (towards the rear of the vehicle) at an angle of 12 from thever cal, and the reactant force must be applied to the seat belt, seat, or roll bara achment point and not the bo om of the roll bar (unless the bo om is the a achmentpoint). Note that there may be one roll bar for the driver and another roll bar for thestoker which will result in each RPS having an applied load of 2670 N, or the driver andstoker can both be protected by a single roll bar which will result in the RPS having anapplied load of 5340 N.The roll bar is acceptable if 1) there is no indica on of permanent deforma on, fracture,or delamina on on either the roll bar or the vehicle frame, 2) the maximum elas cdeforma on is less than 5.1 cm and shall not deform such that contact with the driver’shelmet, head or body will occur.(b) Side Load: A load of 1330 N per driver/stoker shall be applied horizontally to the side ofthe roll bar at shoulder height, and the reactant force must be applied to the seat belt,seat, or roll bar a achment point and not the other side of the roll bar. Note that theremay be one roll bar for the driver and another roll bar for the stoker which will result ineach RPS having an applied load of 1330 N, or the driver and stoker can both beprotected by a single roll bar which will result in the RPS having an applied load of 2670N.The roll bar is acceptable if 1) there is no indication of permanent deformation, fractureor delamination on either the roll bar or the vehicle frame, 2) the maximum elasticdeformation is less than 3.8 cm and shall not deform such that contact with driver’shelmet, head occurs.2) RPS

Nutrition of ruminants Developing production systems for ruminants using tropical feed resources requires an understanding of the relative roles and nutrient needs of the two-compartment system represented by the symbiotic relationship between rumen micro-organisms and the host animal. Fibre-rich, low-protein forages and crop residues are the most abundant and appropriate feeds for ruminants .
