Reverse Design and Finite Element Analysis of the Lower Swing Arm of Automobile Front Suspension
The combination of reverse engineering,computer-aided design and finite element analysis can significantly improve the development efficiency of new products,achieve rapid product manufacturing,and reduce development costs.The lower swing arm of a certain automobile front suspension was the research object in this article.The point cloud data of the lower swing arm was collected using the 3D scanner,and subsequently was processed and simplified.The front suspen-sion lower arm was reverse designed using CATIA software,and a three-dimensional model of the front suspension lower arm was established.The error of the established model was analyzed using Geomagic Qualify software.The average devia-tion was within the range of 0.6mm.Surface smoothing and local structural optimization werecarried out for surface rough-ness,discontinuity,and surface discontinuity.The final lower arm model was conducted with flat and smooth surfaces.This met part design requirements.Using the principle of inertia release,the lower swing arm model was statically analyzed using ANSYS software based on three typical working conditions,and the stress cloud map of the lower swing arm was obtained The results showed that the lower swing arm under various working conditions met the strength requirements.
