摘　　要：为研究点蚀故障对双齿圈人字行星传动系统接触力特征和均载特性的影响规律,基于SolidWorks、KISSsoft以及ADAMS建立了太阳轮健康和存在不同形式点蚀故障时的系统虚拟样机模型。采用GSTIFF积分法动力学求解器对系统接触行为的数值解进行了求解,在此基础上研究了系统接触力时域和频域特征,根据得到的齿轮接触力对系统均载特性进行了分析。结果表明:系统无故障时,齿轮接触力较为平稳呈周期性变化,具有一定的时变特征;系统均载性能良好,基频与系统理论啮合频率一致,频域图中存在谐波频率,频率两侧有明显的边频带;存在点蚀故障时,接触力时域图中出现了周期性峰值,随着点蚀数量和点蚀深度的增加,接触力峰值和均载系数均增大,均载性能变差,基频和谐波频率两侧的边频带越来越密集;圆形点蚀对系统均载性能的影响比矩形点蚀大,点蚀数量的增加对系统均载性能的影响大于点蚀深度增大对系统均载性能的影响。结果为齿轮动力学和故障诊断研究提供了依据。In order to study the influence of pitting faults on the contact force characteristics and load sharing characteristics of double-ring herringbone planetary transmission system,a virtual prototype model of the system was established based on SolidWorks,KISSsoft and ADAMS when the sun wheel was healthy and different types of pitting faults existed.and the numerical solution of the contact behavior of the system was solved by GSTIFF integral dynamic solver.On this basis,the characteristics of the contact force in time domain and frequency domain were studied.The load sharing characteristics of the system were analyzed according to the contact force of the gear.The results show that when the system is fault-free,the contact force of the gear was relatively stable and showed periodic change,with a certain time-varying characteristics.The system has good load sharing performance,and the fundamental frequency was consistent with the theoretical meshing frequency of the system.There are harmonic frequencies in the frequency domain diagram,and there were obvious side bands on both sides of the frequency.In the case of pitting failure,the periodic peak appears in the time domain diagram of contact force.With the increase of pitting quantity and pitting depth,the peak value and load sharing coefficient of contact force increase,the load sharing performance became worse,and the side bands on both sides of fundamental frequency and harmonic frequency became more and more dense.The influence of circular pitting on load sharing performance of the system was greater than that of rectangular pitting,and the influence of the increase of pitting quantity on load sharing performance of the system was greater than that of the increase of pitting depth.The results could provide a basis for gear dynamics and fault diagnosis research.
