摘要: 以 LMS V irtual. Lab Motion为开发环境建立了某传动箱多转子- 轴承系统虚拟样机, 导入 PRO /E模型文
件进行简化, 建立实体模型。针对目前所建立的齿轮传动系统虚拟样机过于简化的情况, 建立了考虑时变啮合
刚度的非线性扭转振动模型。通过组合副和用户自定义程序, 实现了齿轮副和轴承端的耦合振动模型。仿真结
果表明: 通过虚拟样机仿真的方法获得载荷谱是可行的, 其可用于深入研究传动箱的振动分析、强度校核和寿

Abstract: The virtual p rototyp ing dynam ic model of a certain wheel box multi gear rotor bearing system
was constructed by using LMS V irtual. Lab Motion. The PRO /E model was led in and simp lified, and then
the entity model was set up. A t p resent, the virtual p rototyp ing of gear system was too simp le, so the non
linear torsion vibration model was formed, in which time meshing stiffness was considered. Finally, the
coup ling vibration model was set up by mea
