摘　　要：为掌握某多管火箭炮的发射动力学特性,文中利用CAD软件Pro/E建立某多管火箭炮的简化实体模型,然后将其导入ANSYS有限元软件建立有限元模型并计算,得到了详细的模态固有频率和振型,为某多管火箭炮的振动特性分析和结构动力特性的优化设计提供了依据。To determine the dynamic properties of a MLRS,the three-dimensional CAD model of the system was created in Pro/E and then the former was introduced into ANSYS,in which it created the particular finite element model of the system and the modal natural frequencies and vibration mode were obtained.The results are very useful for optimal design.

关 键 词：多管火箭炮 有限元 模态参数
