误用工况下某新能源车型前悬架下控制臂的屈曲分析及优化

Buckling Analysis and Optimization of the Lower Control Arm of the Front Suspension Panel of a Certain Vehicle Model under Misuse Conditions

前悬架下摆臂设计环节中至关重要的是基于误用工况下的屈曲分析。当车辆遭遇剧烈制动通过凹坑或过坎的非常规路况时,前下摆臂会承受超出过大的载荷,从而引发屈曲问题。文章针对某款新能源车型单板前下控制臂进行了有限元分析及优化,确保产品在承受极限负荷时,仍有足够的强度,避免出现塑性变形现象,进而提高车辆的安全性和耐用性。同时,此次分析优化过程也为后续单板控制臂方案屈曲提升提供了参考思路。

It is crucial to conduct buckling analysis based on misuse conditions in the design of the lower arm of the front suspension.When the vehicle encounters unconventional road conditions such as severe braking through potholes or bumps,the front lower arm will bear excessive loads,leading to buckling problems.This article conducts fi nite element analysis and optimization on the front lower control arm of a certain new energy vehicle model,ensuring that the product still has sufficient strength when subjected to extreme loads,avoiding plastic deformation,and thereby enhancing the safety and durability of the vehicle.At the same time,this analysis and optimization process also provides reference ideas for the subsequent buckling improvement of the single board control arm scheme.
