摘要
在某汽车开发过程中,前下摆臂在悬架误用试验工况下发生弯曲。经实车拆解分析,前下摆臂弯曲的原因是在该工况下发生了屈曲。通过建立整车动力学模型,模拟汽车悬架误用试验工况,获取前下摆臂载荷并进行屈曲仿真分析。分析结果显示:该误用工况下,前下摆臂已发生屈曲,屈曲位置和实际弯曲位置一致。基于该误用工况对前下摆臂进行优化设计,制作优化方案样件,经过台架试验验证仿真分析的正确性,并进行实车误用试验,没有发生弯曲。研究为汽车悬架前下摆臂的屈曲性能设计提供了参考。
In the development of a passenger car,the front lower control arm is bent under the misuse test conditions.After real vehicle disassembly analysis,the reason for the bending of the front lower control arm is that the buckling occurred under this working condition.The vehicle dynamics model was established to simulate the misuse test condition of the vehicle suspension,the front lower control arm load was obtained and the structural buckling analysis was performed.The analysis results show that under the misuse condition,the front lower control arm has flexed,and the buckling position is the same as the actual bending position.Based on the misuse condition,the front lower control arm was optimized,the correctness of the prototype was verified by the bench test,and the actual vehicle misuse test is not bent.The research provides reference for the buckling performance design of the front lower control arm of the suspension.
