Novel Design of Lower Arm Vehicle Using Finite Element Analysis and Statistical Method

Abstract

The aim of this study is to investigate the influencing factors of the Lower suspension arm by integrating the finite element technique with response surface methodology (RSM). Response surface methodology has been widely used to predict Stress von Mises on Lower arm systems models. Aluminum alloys (AA7075-T6) are selected as a suspension arm material. The structural model of the suspension arm was developed utilizing the Solid works. The finite element model and analysis were performed utilizing the finite element analysis code. The finite element model is correlated with design of experiments (DOE) modal test. Influences of the various factors namely; Mesh Size, Loads are investigated using RSM. A mathematical prediction model has been developed based on the most influencing factors, and the validation simulation analysis proved its adequacy. RSM was used to design the experiments and analyzed the results obtained. RSM aimed towards prediction stress on Lower arm through the various factors of the suspension arm geometrical construction.
