The Influence of Different Design Parameters by means of Analysis and Optimization in a Car Chassis

Abstract

The main challenge in today’s vehicle industry is to implement the increasing demands for higher performance, longer life, and lower
weight of components so as to satisfy fuel economy demands, at a realistic cost using new safety requirements. In this work, optimum design
parameters of the car chassis were examined by taking into account different chassis types, dimensions, and different materials in order to
achieve minimum weight and deflection. Initially, three chassis types with three sections (Rectangular, L type and Circular) were designed
with the help of Computer Aided Designed (CAD) method via SolidWorksTM software. After that, each design was analyzed using Finite
Element Analyses (FEA) method applying aluminum alloy, magnesium alloy and carbon fiber materials. Forces were applied according to
weights that will be attached to obtain the more realistic results. The consequences of the analysis were optimized by Taguchi method with
Minitab.
