Design and Static Analysis of a Two-Wheeler Suspension System

Abstract

The suspension system is used to observe the vibrations from shock loads due to irregularities of the road surface. It performs function without impairing the stability, steering (or) general handling of the vehicle. Generally, for light vehicles coil springs are used as suspension system. A spring is an elastic object used to store mechanical energy and it can be twist, pulled (or) stretched by some force and can return to their original shape when the force is released. The present work attempts to analyze the safe load of the light vehicle suspension spring with different materials.

This investigation includes comparison of modelling and analyses of primary suspension spring made of low structural steel and aluminium alloy and suggested the suitability for optimum design.

 3D model design of the shock absorber is carried out using the CATIAv5R20 modelling software. It is imported to ANSYS analysis software where the desired stress and deformation by static analysis and results are obtained for further comparison to get a conclusion. The results show the reduction in overall stress and deflection of spring for chosen materials.
