摘要
悬架总成是车辆底盘的重要组成部分,其主要作用是传递地面对车辆的作用力,平衡车身,同时缓冲由于不平路面引起车辆的振动。针对某车后悬架开裂故障引发的安全问题,利用有限元计算进行原因分析,并通过对比分析提出改进方案。相比传统的经验设计方法,利用有限元方法分析得出的改进方案更为有效,提高可靠性且使质量及成本控制更为合理。
Suspension assembly is an important part of the vehicle chassis. Its main roles are to transmit the force from the ground,to balance the body,and to buffer the vibration of vehicle caused by uneven road. Aiming at the security problems caused by the car＇s rear suspension cracking fault,finite element analysis was used to analyze the causes,and solutions were proposed through analysis. Compared with traditional empirical design method,the improved scheme based on finite element analysis method is more effective,the reliability is improved and the quality and cost control is more reasonable.
