Finite Element Analysis and Optimization of a Full Frame Front Sub Frame

对某全框式前副车架设计数模进行有限元分析,发现其纵臂与上下片搭接结构存在设计缺陷,在分析结构缺陷问题后对前副车架结构进行优化设计,优化后的数模不仅满足结构强度的要求,还降低了重量,达到了优化的目的。

Through the finite element analysis of the design of a full frame front sub frame,it is found that there isa design defect in the lap structure of the longitudinal arm and the upper and lower pieces. After analyzing theproblem of structural defects,the optimal design of the structure of the front sub frame was carried out. The optimized model not only satisfies the requirement of structural strength,but also reduces the weight,and achieves theaim of optimization.
