摘　　要：车架作为移动式空压机的主要承载部件,其结构强度对空压机使用性能有很大的影响。在某移动式空压机车架结构设计时,最关心的问题之一是车架被吊起时的结构强度是否满足要求。按企业标准,应用有限元分析手段,对移动式空压机车架建立有限元模型,并在起吊工况下对其进行结构强度分析。结合应力应变电测试验,将有限元分析数据与电测试验数据进行对比,找出车架结构的薄弱环节,并加以改进。力图找到一个能有效节约移动式空压机车架开发设计成本的方法和手段。Frame is the main load bearing parts of mobile air compressor, and the structural strength of air compressor has a great influence on usability. In the design of the frame structure on a mobile air compressor, one of the most concerned issues is whether the structural strength of the frame meets the requirements when it is hoisted. According to the standards of the enterprise, finite element analysis method is applied to establish the finite element model of the frame structure on the mobile air compressor, and the structural strength of the frame on the mobile air compressor is analyzed under the working condition of hoisting. Combined with stress and strain test, the data of finite element analysis and test are compared to find out the weak position of the frame structure and improve it. The purpose is tries to find a method which can effectively save cost of designing the frame on mobile compressor.
