基于齿轮啮合刚度的履带车辆变速箱固有特性研究

Research on Natural Characteristic of Tracked Vehicle Gearbox Based on Gear Meshing Stiffness

考虑齿轮啮合刚度波动的影响,对履带车辆变速箱进行了理论建模。计算得到关于固有特性的几个结论,为系统动态响应分析提供了必要的依据,对变速箱故障诊断具有一定借鉴意义。

The fluctuation of gear meshing stiffness is considered, and the theoretic model is done for gearbox. The results are obtained about natural characteristic in the paper, which is valid enough to provide the foundation for the dynamic response evaluation. There is a specific significance to identify and locate the cause of gearbox faults.
