摘　　要：前摆臂作为麦弗逊前悬架的重要零部件,担负着至关重要的作用,其结构除满足强度要求外,还要承受一定的屈曲性能,需提前破坏弯曲,起到保护副车架的作用,(超)高强钢与单片式的前摆臂已经成为行业发展的主流结构。文章介绍了前摆臂屈曲性能要求、屈曲分析流程、分析方法、分析工况等,并以某开发车型的前摆臂为例,利用HyperMesh建立其有限元模型,在ABAQUS中进行屈曲计算,研究总结出一系列的屈曲优化方法,计算结果表明优化方法有效,对前摆臂屈曲设计有重要的指导作用。As an important part of Mcpherson front suspension,the front lower arm plays an important role.Its structure not only meets the strength requirements,but also bears certain buckling performance,which needs to destroy bending ahead of time to protect the sub-frame,(super)high strength steel and single-chip front lower arm has become the mainstream structure of industry development.In this paper,the buckling performance requirements,buckling analysis process,analysis method and working conditions of the front lower arm are introduced,and take the front lower arm of a developed vehicle as an example,the finite element model of the front lower arm is established by HyperMesh,and the buckling calculation is carried out in ABAQUS,a series of buckling optimization methods are summarized,and the calculation results show that the optimization method is effective and has important guidance for the design of front lower arm buckling.
