行星齿轮广泛用于需要紧凑性和高扭矩重量比的航空和工业应用中。尽管有这些优点，但通常使用这种齿轮的恶劣条件可能导致故障。齿面点蚀和裂纹是常见的失效形式。针对行星齿轮组的缺陷进行了建模和讨论。研究了轮齿缺陷对齿轮啮合刚度的影响。利用Wigner-Ville分布，在时域、频域和联合时频域对健康行星齿轮和含齿缺陷行星齿轮的动力学响应进行了比较。
Planetary gears are widely used in aeronautic and industrial applications that require compactness and high torque-to-weight ratios. Despite these advantages, the severe conditions under which such gears are typically used may lead to failure. Tooth pitting and cracking are frequently encountered failure modes. The defects are modeled and discussed for a planetary gear set. The influence of tooth defects on gear mesh stiffness is scrutinized. Healthy planetary gear dynamic response and the response of planetary gears containing tooth defects are compared in both the time and frequency domains and in the joint time-frequency domains by use of the Wigner-Ville distribution.
