摘　　要：针对某移动式空气压缩机在路试过程中车架出现早期断裂的问题,利用有限元法对车架进行牵引工况下的结构强度分析;分析结构薄弱环节,找出车架断裂的原因;提出改进方案,并对改进后车架进行有限元分析及路试,路试结果表明:此改进方案成功解决了车架断裂的问题。This article focused on the problem of the earlier fracture of a mobile air compressor during the process of road test. Under the condition of traction, the finite element method was often used for structure strength analysis of frame. Firstly, the cause of the frame fracture was found out using the analysis of weak link of the structure. Then the improved scheme was proposed to analyze the improved frame using finite element method and road test. The results of road test showed that the im- proved scheme successfully solved the problem of the frame fracture.
