Abstract

This paper investigates the vibration response from the planetary gearbox with a flexible ring gear, supported by various constraints, resulting in quite different vibration spectra. The ring gear with its supports was modelled in ANSYS as a transient finite element moving load beam problem to formulate the vibration response. The moving load was represented by the dynamic gear mesh forces, which were obtained from a planetary gear lumped-parameter model. Two support conditions were analysed in this research. In the uniform support condition, it was found that the modulation effect from the carrier arm rotation can be accurately predicted and the vibration spectra matched well with previous publications. In the pin support condition, the spectra from different ring gear rim locations can result in different vibration spectra and it provides a primer guideline for further understanding the effect of the sensor location on the planetary gear vibration monitoring.
行星齿轮与柔性环齿的振动响应
本文研究了具有柔性环齿的行星齿轮箱在不同约束条件下的振动响应,得到了不同的振动谱。在ANSYS中对带支承的环形齿轮进行了瞬态有限元动荷载梁问题的建模,得到了其振动响应。运动载荷由行星齿轮集中参数模型得到的动态齿轮啮合力表示。本研究分析了两种支护条件。在均匀支承条件下,可以准确预测载臂旋转的调制效应,且振动谱与文献吻合较好。在销支撑条件下,不同齿圈位置的振动谱会产生不同的振动谱,为进一步了解传感器位置对行星齿轮振动监测的影响提供了初步指导。

期刊介绍: IJPT addresses novel scientific/technological results contributing to advancing powertrain technology, from components/subsystems to system integration/controls. Focus is primarily but not exclusively on ground vehicle applications. IJPT''s perspective is largely inspired by the fact that many innovations in powertrain advancement are only possible due to synergies between mechanical design, mechanisms, mechatronics, controls, networking system integration, etc. The science behind these is characterised by physical phenomena across the range of physics (multiphysics) and scale of motion (multiscale) governing the behaviour of components/subsystems.
