原文
The effectiveness of planet phasing to suppress planetary gear vibration in certain
harmonics of the mesh frequency is examined based on the physical forces acting at the sun-planet and ring-planet meshes. The analysis does not rely on assumptions of the nature of the dynamic excitation (e.g., static transmission error or time-varying mesh stiffness) or on an underlying dynamic model. Instead, the inherent system symmetries imply distinct relationships between the forces at the multiple meshes. These relationships lead naturally to simple rules for when a particular harmonic of mesh frequency is suppressed in the dynamic response. An important implication is that certain expected resonances when a mesh frequency harmonic and a natural frequency coincide are suppressed. Systems with equal planet spacing and those with unequally spaced, diametrically opposed planets are considered. In both cases, a substantial number of mesh frequency harmonics are suppressed naturally without optimization of the phasing. The phenomena are demonstrated with a dynamic finite element/contact mechanics simulation.

用行星相位调整法来抑制行星传动装置震动的可行性可以通过施加在行星轮-太阳轮，行星轮-内齿轮啮合处的作用力进行验证。这种分析并不是基于动态激励的性质（例如，静力传递误差或是随时间变化的啮合强度）或基于某一种基本的动力学模型。相反的，固有的系统对称性明确的表明了作用在多重啮合中的两个力之间关系。这些关系就很自然的形成了一些简单的适用于当一个特定的啮合频率谐波被动态响应抑制时的规则。其中一个重要的表现就是，当啮合频率谐波和齿轮的固有频率相同时，某些预期共振会被抑制。那些等间隔行星轮系和非等间隔行星轮系都考虑过沿直径方向相对分布行星轮。在以上两种情况中，没有进行最优化相位调整地啮合频率谐波的实际数值被自然的抑制了。这种现象可以通过一个动态有限性构件/约束的力学仿真模型来论证
