摘要
讨论了应用有限元法进行车载炮摇架和上架静动态设计的方法,建立了摇架和上架的有限元模型,叙述了摇架和上架作为一个整体时的受力分析及单元类型的选择．通过静态刚度和强度分析,得到摇架和上架静载作用下的最大位移和应力,通过动态响应分析了解到其动态特性．由此找出了原方案结构设计中存在的问题及结构的薄弱环节,通过对结构的改进使其逐步达到设计要求．所提到的方法可推广到火炮其它部件的结构动态设计中．
The static and dynamic design of the cradle and top carriage for the vehicle-mounted howitzer using finite element method is discussed. Loads on the cradle and top carriage as a whole are analyzed, and a choice of element types is made. Through static stiffness and strength analysis, the maximum displacement and stress under static loads are obtained. Through dynamic response analysis, dynamic characteristics are obtained. Further, bottlenecks and other problems in the design of the original scheme are found. Then, the step by step until the design requirement is satisfied. This method can be applied to structural design is revised dynamic design of other components of the gun.
