CATIA V5 AnalysisStudent Notes:What is Assembly Structural AnalysisAssembly Structural Analysis is generally used to perform structural analysis of assemblies.In this, physical assemblies are modeled using Finite Element Assemblies.While designing, structural analyses of individualparts are performed. These parts are commonlycomponents of a product.For example, an analysis of a crankshaftproduces the information about the structural,dynamic response of the component underan applied load, which can be used toimprove the crankshaft design.Crank shaftCopyright DASSAULT SYSTEMESA crankshaft is one of the parts ofengine assembly which also containsconnecting rod, pin, piston, bolts etc.Once these individual parts are assembled,it is necessary to understand the structuraland dynamic behavior of the assembly.Therefore, assembly analysis is required.Copyright DASSAULT SYSTEMESCrank shaft in engine assembly6

CATIA V5 AnalysisWhat is Generative Assembly Structural Analysis (1/5)Student Notes:The Generative Assembly Structural Analysis (GAS) licenseprovides functionalities for analysis of assembly, through theGenerative Structural Analysis workbench. It allows you todefine the connections between the assembly componentsand assign different types of connection properties to theseconnections to simulate the real connection behavior.In other words, ‘GAS’ allows you to define real constraintsusing connection properties. It lets you define four differentkinds of connection properties:Face/Face Connection propertiesDistant Connection propertiesWelding Connection propertiesCopyright DASSAULT SYSTEMESGPSAeroConnection containerTo be able to create the connection properties, you musthave previously defined ‘Assembly constraints’ or ‘AnalysisConnections’ using GAS Workbench. You must ensure thatyour assembly is properly constrained (i.e., neither overconstrained nor under-constrained).Copyright DASSAULT SYSTEMES7

CATIA V5 AnalysisStudent Notes:What is Generative Assembly Structural Analysis (2/5)When you work with the Analysis workbench, the following assumptions are imposed:Small displacements (translation and rotation)Small strainLinear constitutive law: linear elasticityThus, if there is no contact feature (either virtual orreal), no pressure fitting property and no bolttightening feature (virtual or not), then the problemis linear which means that the displacement is alinear function of the load.RigidConnectionpropertyLinear ProblemCopyright DASSAULT SYSTEMESOn the other hand, If there is at least one contactfeature (either virtual or real) or pressure fittingproperty or bolt tightening feature (virtual or not),then the problem is nonlinear, which means that thedisplacement is a non linear function of the load.Copyright DASSAULT SYSTEMESPressure FittingConnectionpropertyNon-linear Problem8

CATIA V5 AnalysisStudent Notes:What is Generative Assembly Structural Analysis (3/5)We have two basic approaches to perform Generative Assembly Structural analysis – AssemblyAnalysis and Analysis AssemblyAAssembly Analysis:A.B.C.D.Copyright DASSAULT SYSTEMESE.F.The product document is available. You willswitch to analysis workbench to createanalysis document which will be the onlyanalysis document in this approach.The default OCTREE Tetrahedron Meshparameters are automatically applied to 3Dcomponents in product structure.In similar way, 3D Properties areautomatically applied to 3D components.For 1D or 2D components you will applymesh parameters and properties manually.You will assign Connection Propertiesbetween components either by creatinganalysis connections or by re-using existingassembly constraints.Finally, analysis of the complete assembly isperformed.Copyright DASSAULT SYSTEMESGlobal analysisDocumentProduct structurelinked in analysisDocumentBCMesh parameters forcomponents andConnection propertymeshes will becreated here3D Properties will beautomatically applied.EFConnectionproperties will becreated hereAnalysis Objectsand results9

CATIA V5 AnalysisWhat is Analysis AssemblyStudent Notes:In this approach, analyses of individual parts in a product are available. These analyses are assembled toform an ‘Analysis Assembly’ and then a final ‘Global Analysis’ is performed for the product.While following this approach you have the option ofusing an available product with assemblyconstraints. In case a product is not available, youcan create a product document and directly attachindividual part analysis files in the productdocument. These analysis files must be computedwith at least ‘Mesh only’ option, so that it containsMesh and complete FE property information .Copyright DASSAULT SYSTEMESThe Analysis Assembly approach has followingadvantages:It uses already meshed individual parts andimported orphan mesh parts effectivelyWhen a single part is used in multipleassemblies, you need to mesh that part onlyonce.It enables concurrent engineering of FEAnalysis. It is possible to mesh individualparts in an assembly simultaneously bydifferent users at different locations.It reduces the time required to analyze largeassemblies.It facilitates management of analysis data.Copyright DASSAULT SYSTEMES13

CATIA V5 AnalysisStudent Notes:What is Shape RepresentationThe analysis document is an alternate shaperepresentation of the Part document. Attaching theFE analysis document to a part is known asattaching shape representation to part. It is definedby using the ‘Manage Shape Representation’ optionin the product’s contextual menu.Shape RepresentationCopyright DASSAULT SYSTEMESFor a given part there can be more thanone shape representation.You can attach any number of shaperepresentations to a part.At a time only one shape can be active.PartCopyright DASSAULT SYSTEMES14

CATIA V5 AnalysisWhy Use Connections and Connection PropertiesIn the finite element model, you must define how the parts ofan assembly interact with each other. GAS connections are aneasy way for you to define interactions between parts withoutmodeling all the physical details of the joint. A wide variety ofconnection types and connection properties are provided tomodel physical assembly connections. When parts are connected to each other, the relationshipsbetween the translational and rotational degrees of freedom atthe connection are well defined. The characteristics of theserelationships are determined by the structural properties of theconnection itself. For example, when two parts are connected with a springjoint, the spring stiffness plays a role in how forces aretransmitted from one part to the other. This stiffness willdictate how the connected parts move relative to each other. You can utilize the constraints defined in assembly in order todefine connection physical properties.Copyright DASSAULT SYSTEMES Student Notes:Copyright DASSAULT SYSTEMES26

CATIA V5 AnalysisUsing Assembly Constraints for Analysis ConnectionsStudent Notes:You can use either assembly constraints or a corresponding analysis connection in order to define aconnection property. Thus, if assembly constraints are already defined then there is no need to createan analysis connections as support for creating connection property.You need to create an analysis connection if an assembly constraint is not available for a requiredjoint. You will see which are the most appropriate constraints for each kind of connection.Copyright DASSAULT SYSTEMESConstraintsEquivalent Analysis ConnectionCoincidence constraintGeneral Analysis ConnectionContact constraintLine Analysis ConnectionOffset constraintPoint Analysis ConnectionFix constraintSurface Analysis ConnectionCopyright DASSAULT SYSTEMES27

CATIA V5 AnalysisStudent Notes:Applying General Analysis ConnectionGeneral Analysis Connection is used for connecting parts of an assembly, with or without handlerpoint. This operation can be performed between any type of geometry.Follow the steps given below to create a General Analysis Connection between a piston pin andconnecting rod:Click on the General AnalysisConnection icon.2.Select the outer surface of the Pinwhich is in contact with Rod as Firstcomponent.3.Select the inner surface of the Rodin contact with Pin as Secondcomponent.4.Click OK.132First Component asOuter surface of PinSecond Component asinner surface of RodCopyright DASSAULT SYSTEMES1.Copyright DASSAULT SYSTEMES28

CATIA V5 AnalysisStudent Notes:Applying a Fastened Connection PropertyA Fastened Connection property is the link between two bodies which are fastened together at theircommon boundary. The two bodies behaves as if they were a single one, however they can havedifferent material properties. A Fastened Connection takes into account the elastic deformability ofthe interface.Follow the steps given bellow to apply fastenedConnection Property.1.Click on the FastenedConnection icon.2.Select the constraint previously created inProduct Design workbench or appropriateAnalysis Connection in Supports field.Generally you can select one of theconstraint from contact, coincidence andoffset constraints, or a General AnalysisConnection of any type except point/pointtype, as a support.Click OK.Copyright DASSAULT SYSTEMES3.A symbol representingthe Fastened ConnectionProperty appearsCopyright DASSAULT SYSTEMES12332

CATIA V5 AnalysisStudent Notes:Applying Contact Connection PropertyA Contact Connection is the link between the two part bodies which are prevented from interpenetrating at their common boundary. The two bodies are free to move arbitrarily relative to each otheras long as they do not come into contact or within a user-specified normal clearance. When they comeinto contact or are at the clearance distance, they can still separate or slide relative to each other in thetangential plane, but they cannot come any closer than the user-specified clearance.The Contact Connection is designed to handle the incompatible meshes and take into account the elasticdeformability of the interfaces.Copyright DASSAULT SYSTEMESFollow the steps given bellow to apply ContactConnection Property.1.Click the Contact Connection icon.2.Select the constraint previously createdin the Assembly Design/AnalysisConnection workbench, for Supports.Generally you can select one of theconstraint from contact, coincidence andoffset constraints, or a General AnalysisConnection of any type exceptpoint/point type, as a support.3.Click OK.Copyright DASSAULT SYSTEMES12A symbolrepresentingthe contactConnectionappears2333

CATIA V5 AnalysisStudent Notes:Applying Rigid Connection PropertyA Rigid Connection is the link between two bodies which are stiffened and fastened together at theircommon boundary, and will behave as if their interface was infinitely rigid.The Rigid Connection relations do not take into account the elastic deformability of the interfaces.A central node, created at the midpoint between centroids of the two systems of points represented by thenodes of the two meshes, is connected by a rigid beam element to each node of the first and of the secondmeshes.Follow the steps given bellow to apply Rigid Connection Property.Click the Rigid Connection icon.2.Select an assembly constraint : ‘coincidence’Generally you can select one of theconstraint from contact, coincidence andoffset constraints, or a General AnalysisConnection of any type, as a support.3.Check the Transmitted Degrees ofFreedom option to transmit somerequired Degrees of Freedom to thedistant connection, if needed.4.Click OK.Copyright DASSAULT SYSTEMES1.Copyright DASSAULT SYSTEMESA symbolrepresentingthe RigidConnectionPropertyappears122434
