Dynamic stiffness optimization of engine mounting point of front crossmember of a new vehicle
In this paper,the dynamic stiffness of the engine mounting point of the front crossmember of a new vehicle was op-timized.Based on the comprehensive consideration of the dynamic stiffness analysis results and the structure of the parts,the causes of the weak dynamic stiffness were analyzed,and the improvement direction was obtained.The final optimization scheme was obtained step by step,and the universal improvement idea of the dynamic stiffness of the structural components of automotive chassis was summarized.Where the dynamic stiffness is weak(one or more of the X,Y,Z directions),the sup-port should be increased,and the structure of the parts should be improved step by step to get the optimal improvement scheme.This improvement idea can be used as the design guide for new parts development or original parts improvement.
