Jib Crane Analysis using FEM (IJSRD/Vol. 3/Issue 04/2015/049) A. Deflection At Free End Fig. 5: Deformation of Column (Mast) Fig. 3: Deflection At Free End The deflection at the free end obtained by Finite Element based software ANSYS is 2.891 mm. The same is seen in the figure No 3. Ansys 2.891 mm Observing the analytical & Finite Element analysis values it can be said that the type of element & mesh density used for above analysis is correct. The maximum stress for the above case is also observed in the post processing. B. Maximum Stress Is Also Observed In The Post Processing. The Same Is Shown Figure No 4. Fig. 6: Three Dimensional Model of the Jib Crane Fig.4. Maximum Stress Is Observed In The Post Processing Is Shown. Maximum Stress (Direct Bending) 30.707MPa (1.5) C.

Load condition & Boundary condition are used as in Table No. 4. Load condition: Load applied is a tensile force of 1000 N. Boundary condition: All motions of the bottom end are constrained Fig. 8: Deformation of Jib Crane During the post-processing Von Mises Stresses are also observed. The maximum value of Von Mises Stress is 108.849 MPa. Figure No. 9. shows Von Mises stresses at All rights reserved by www.ijsrd.com 187

Jib crane, a type of crane where a horizontal member (jib or boom) is supporting and moveable hoist, a key element of hoisting mechanism as an integral part of the machine. A typical jib crane consists of a top beam which is rotating around a fixed column. This configuration may be referred
