摘　　要：车架是整个汽车承载基体,承载汽车大部分载荷,其性能直接影响整车的性能。针对某型特种半挂车上装设备使用的特殊要求,借助有限元方法建立了该半挂车架的计算模型,研究了车架弯曲工况下的静态特性。通过应变电测试验与有限元分析结果对比,验证了有限元分析模型及分析方法的正确性,为模型进一步的改进和优化提供依据。As the main bearing part of the vehicle, most of the load was undertaken by the frame, so its performance directly influence the performance of vehicle. According to the special requirements for equipment of semi-trailers, a calculation model of the frame was established with the finite element method, which static characteristics under bending conditions were analyzed. Use with experimental results of electrical test strain, the correctness of the model and the analysis method is verified and to provide the basis for further improvement and optimization.
