Topology Optimization of the Double Wishbone Suspension System Components and Vibration Analysis

Abstract

Topology Optimization is an optimization process in which the shape and size are changed, or the mass of mechanical components is reduced by keeping the material properties within safe limits. The conventional topology optimization formulation uses the finite element method to evaluate the design performance. This work proposes a methodology to optimize the double wishbone suspension arms to reduce their weight to improve the suspension parameters. The scope for reducing the un-sprung mass and improving the performance of the suspension components and reducing the vertical acceleration of the vehicle is identified for topology optimization. Creation of a 3D CAD model using the CATIA V5 software followed by structural and modal analysis on the ANSYS 18.1 software and topology optimization is carried out to monitor the results of the modified system.
