摘要

针对一般斜齿轮定位问题,建立了两级齿轮系统三维动力学特性模型。这种激励是由网格刚度的周期性变化引起的。本案例描述了齿轮的实际工作情况。首先,对系统进行了模态分析。然后,采用分步时间积分法(Newmark法)计算动力响应。最后,在模型中介绍了齿轮的两种制造缺陷:偏心缺陷和齿形缺陷。然后对这些缺陷对齿轮系统动态行为的影响进行了分析。

Effect of manufacturing defects on the dynamic behaviour for an helical two-stage gear system
The modelling of the dynamic behaviour of three-dimensional model of two-stage gear system is formulated for general helical gears location. The excitation is induced by the periodic variation of the mesh stiffnesses. This case describes the real working of the gearings. First, the modal analysis of the system is treated. Then, the calculation of the dynamic response is performed by a step-by-step time integration method (Newmark method). Finally, two types of manufacturing defects on the gears are introduced in the model: eccentricity and profile defect. An analysis of the effects of these defects on the gear system dynamic behaviour is then treated.
