摘要:某型牵引火炮后坐装置的虚拟样机动力学模型以 LMS 为开发环境建立。先导入 PRO/E 模型
文件进行简化,并添加约束关系建立火炮上架以上部分的实体模型。再借助 用户自定义子程序模版 TSDA,
通过 Fortran 语言编程实现后坐与复进行程函数元素的添加。以 0°全装药射击对虚拟样机进行验证,采用最大值法
比较比后坐位移和速度的仿真值与实验值,所得误差在工程应用范围内,满足工程应用需要。

Abstract: The virtual prototyping dynamic model of a certain gun recoil system is constructed by using LMS
. The PRO/E model is introduced and simplified, and then the gun top carriage entity model is set up by adding
certain constraints. Then, the backlash and counter-recoil functions are formed by means of FORTRAN and
user-defined subroutines TSDA. Finally, virtual prototyping is tested by full-charge fire at 0o, the simulated displacement
and velocity results pared with the experimented data by using the maximum method, th
