自然频率和振动模式的系统参数的灵敏度进行了严格的调查调谐（循环对称）和失谐行星齿轮。考虑的参数包括支撑和网格刚度、组件质量和惯性矩。利用调谐行星齿轮的明确定义的振动模式属性，计算的特征灵敏度，并表示在简单，准确的公式。这些公式将固有频率灵敏度与模态应变或动能联系起来，并通过检查模态能量分布来确定对所有刚度和惯性参数的灵敏度。计算固有频率对运行速度的灵敏度，以估计陀螺效应的影响。虽然行星齿轮的术语在全文中使用，但结果适用于一般的周转齿轮。(C)北京：科学出版社.
The natural frequency and vibration mode sensitivities to system parameters are rigorously investigated for both tuned (cyclically symmetric) and mistuned planetary gears. Parameters under consideration include support and mesh stiffnesses, component masses, and moments of inertia. Using the well-defined vibration mode properties of tuned planetary gears, the eigensensitivities are calculated and expressed in simple, exact formulae. These formulae connect natural frequency sensitivity with the modal strain or kinetic energy and provide efficient means to determine the sensitivity to all stiffness and inertia parameters by inspection of the modal energy distribution. The natural frequency sensitivity to operating speed is calculated to estimate the impact of gyroscopic effects. While the terminology of planetary gears is used throughout, the results apply for general epicyclic gears. (C) 1999 Academic Press.
