摘要

以国内某现役地铁齿轮箱实体为研究对象，构造计算机虚拟样机，并借助有限元软件构造含有柔性箱体的刚柔耦合模型，探讨了不同测点位置的振动信号特性，分析了断齿数量变化、转矩变化、转速变化情况下的齿轮箱箱体振动特性。结果表明，测点位置距离轴越近，对冲击能量越敏感，但相对的其频域特性模糊；断齿数量、转矩、转速的增大都会导致振动整体加剧，局部上又呈现出各自不同的特性。研究结果对地铁齿轮箱的仿真及试验研究具有一定参考价值。

Abstract

Taking a subway gearbox in service in China as the research object，a computer virtual prototype is constructed and a rigid-flexible coupling model with a flexible gearbox is constructed by using finite element software，the vibration signal characteristics of different measuring points are discussed，and the vibration characteristics of the gearbox body are analyzed under the change conditions of the number of broken teeth，the torque and the speed. The results show that the closer the measuring point is to the axis，the more sensitive it is to the impact energy，but the relative frequency domain characteristics are fuzzy. The increase of the number of broken teeth，torque and speed will lead to the aggravation of vibration，and presents different vibration characteristics locally. The research results have certain reference value for the simulation and experimental research of subway gearbox.
