Abstract: A torsion bar is a type of suspension system that is usually used in vehicles such as cars, trucks and vans. A
suspension system is a significant and acute element of a vehicle’s design. Irrespective of the design, all suspension systems
do the same functions. They keep the tires in contact with the surface of the road, upkeep the weight of a vehicle and absorb
the forces produced by the movement and motion of the vehicle. This project presents an application of Finite Element
Analysis (FEA) for strength improvement of torsion bar. Alsoprovides fundamental knowledge of torsion bar analysis using
composite material. The existing torsion bar is modelled using CATIA and analyzed using ANSYS 19.0. First optimization is
done based on fiber orientation angles of composite material. Further alternate material selection is done through study and
optimization analysis is done for the same. Carbon epoxy-glass fiber selected as material. Finite element analysis of both
shafts will be done under torsional loading using ANSYS 19.0. CATIA V5 will be used for CAD modeling/Design of both
shafts. Experimental investigation will be done by Torque Test. Comparative analysis of FEA and Experimental will be done
for validation of work. Conclusion and future scope will be suggested.
