摘要: 目的研究不同程度断齿-点蚀复合故障对人字行星齿轮传动的接触力特性、振动响应特征和动载系数等的影响规律。  方法基于KISSsoft，SolidWorks和ADAMS，分别建立健康、不同严重程度断齿-点蚀复合故障的双齿圈人字行星齿轮传动系统的精准虚拟样机模型，采用GSTIFF算法求解获得健康与不同程度断齿-点蚀故障下的系统接触力和角加速度，进而计算健康、不同程度复合故障系统动载系数。分析系统在时频域上内外啮合副接触力特性、角加速度响应等变化规律，探讨故障严重程度与系统动载系数之间的关联规律。  结果结果表明：健康状态下系统理论啮合频率与基频频率误差小于1％，验证了虚拟样机模型的准确性。发生断齿-点蚀复合故障时，接触力和角加速度时域曲线波动幅度显著增大，频域出现明显的边频带。健康系统内外啮合副动载系数为1.005，1.004，系统传动性能稳定。 结论随着断齿-点蚀故障程度加剧，接触力和角加速度时域曲线出现多个峰值，频域边频带变得更密集，系统内外啮合副动载系数持续增大。相较于轻度、中度复合故障，严重断齿-点蚀故障对系统传动性能影响最为显著。研究结果为行星齿轮传动复合故障精准诊断与动力学仿真提供了理论依据。

Abstract: Objectives The influence of compound faults of broken tooth-pitting at different severity levels on the contact force characteristics， vibration response features， and dynamic load coefficients of a herringbone planetary gear transmission system was investigated.  Methods Based on KISSsoft， SolidWorks， and ADAMS， accurate virtual prototype models of a double-ring herringbone planetary gear transmission system under healthy condition and with different severity levels of broken tooth-pitting compound faults are established. The GSTIFF algorithm is employed to obtain the system contact forces and angular accelerations under healthy and various compound fault conditions， from which the dynamic load coefficients are calculated. The contact force characteristics and angular acceleration responses of the internal and external meshing pairs in the time and frequency domains are analyzed， and the relationship between fault severity and the system dynamic load coefficient is investigated.  Results The results show that under the healthy condition， the error between the theoretical meshing frequency and the fundamental frequency is less than 1%， validating the accuracy of the virtual prototype model. When a broken tooth-pitting compound fault occurs， the fluctuation amplitudes of the contact force and angular acceleration in the time domain increase significantly， and distinct sidebands appear in the frequency domain. The dynamic load coefficients of the internal and external meshing pairs in the healthy system are 1.005 and 1.004， respectively， indicating stable transmission performance. Conclusions As the severity of the broken tooth-pitting compound fault increases， the time-domain curves of contact force and angular acceleration exhibit multiple peaks， the sidebands in the frequency domain become denser， and the dynamic load coefficients of the internal and external meshing pairs continue to increase. Compared with mild and moderate compound faults， severe broken tooth-pitting faults have the most significant impact on the transmission performance of the system. The findings provide a theoretical basis for accurate diagnosis and dynamic simulation of compound faults in planetary gear transmission systems.
