为检验某车载迫击炮车架结构是否满足设计要求，通过有限元方法对其分别进行了静、动态分析。利用Solidworks三维设计软件建立车架的三维实体模型，对车架结构进行合理简化后导入到有限元分析软件ABAQUS中进行刚强度分析计算，得到车载迫击炮射击过程中车架的应力和位移变化曲线。结果表明：动态分析的结果更接近真实受力状况，车架的整体刚强度性能基本符合要求，但第6横梁处局部应力大于材料许用应力，需考虑加厚，并提出改进措施，改进后的结果表明，车架刚强度符合设计要求。

In this paper we carried out the static and dynamic analysis by finite element method in order to check out the vehicle-mounted mortar’s frame construction whether it reached the design requirements. The frame model is built with Solidworks(the three-dimensional design software), which is imported into ABAQUS(the finite element analysis software) after it is properly simplified, and then its finite element simulation of stiffness and strength is calculated, the stress and the curve of displacement is gained. The results show that the results of dynamic analysis is more closer to the real stress condition, and the overall stiffness and strength performance of the frame is correct basically, but the local stress of the sixth crossbeam is greater than the material allowable stress, so thickness should be considered and put forwards some improving measures, the results of improvement show that frame stiffness and strength satisfies the designing requirements.
