Research paper on Design and analysis Double Wishbone Suspension system using Finite Element Analysis

Abstract

Double wishbone designs allow the engineer to carefully control the motion of the wheel throughout
suspension travel. 3-D model of the Lower Wishbone Arm is prepared by using CAD software for modal and stress
analysis. The forces and moments are used as the boundary conditions for finite element model of the wishbone
arm. By using these boundary conditions static analysis is carried out. Then making the load as a function of time;
quasi-static analysis of the wishbone arm is carried out. A finite element based optimization is used to optimize the
design of lower wishbone arm. Topology optimization and material optimization techniques are used to optimize
lower wishbone arm design.
