摘要
某型牵引火炮后坐装置的虚拟样机动力学模型以LMS Virtual.Lab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Virtual.Lab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。
The virtual prototyping dynamic model of a certain gun recoil system is constructed by using LMS Virtual.Lab. 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 Virtual.Lab user-defined subroutines TSDA. Finally, virtual prototyping is tested by full-charge fire at 0°, the simulated displacement and velocity results arre compared with the experimented data by using the maximum method, the error is limited in the scope of engineering application and the simulated results is useful.
