Abstract

The objective of this study is to attempt the possibility of identifying optimum stress distribution of conventional mono leaf spring (MLS) using finite element analysis. In addition, this study includes the topology optimization model based on equivalent static load. This paper describes two different approaches considering design for manufacturing after obtaining results from topology optimization. The proposed method is to create circular holes along the leaf spring and cutting a uniform slot along the spring. Although, Finite element analysis is accomplished to analyse the effect on MLS after removing material. The results of this investigation revealed that a weight reduction can be possible in MLS to obtain light weight and structurally strong design that can be used in Electric Vehicle. The proposed method is part of ongoing research and it will offer to the market on demand. This approach successfully predicts that a percentile weight reduction of about 2.3% with holes and 8.16% with slot can be obtained in conventional MLS.
