Computational evaluation of automotive camber component for light‐weight design

Abstract

AbstractDue to global warming, environmental issues are one of the most interesting issues in the world. Especially for automobiles that emit pollutants, the issue of lightweight design is one of the important research areas. Thus, this study deals with the lightweight design of a camber link, an automotive suspension component, through finite element analysis. With reference to the camber link made of steel (SM45C) material that has been proven by commercialization, we will replace it with A356 aluminum alloy material to reduce the weight. Here, the design was changed through finite element analysis to reinforce the reduction of rigidity due to material substitution. In particular, we propose a method of designing a camber link considering the safety factor by analyzing the change of stress applied to the suspension. The weight reduction of about 14 % was achieved through static analysis using the weight factor. Using the dynamic optimization method through static analysis using the weight factor and stress ratio, it can be seen that the application is convenient and easy for the lightweight and optimal design of automobile parts.
