含断齿-点蚀复合故障人字行星齿轮传动系统动态特性研究
Research on dynamic characteristics of a herringbone planetary gear transmission system with broken tooth-pitting compound fault
摘要
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 herring-bone 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 estab-lished.The GSTIFF algorithm is employed to obtain the system contact forces and angular accelerations un-der healthy and various compound fault conditions,from which the dynamic load coefficients are calcu-lated.The contact force characteristics and angular acceleration responses of the internal and external mesh-ing 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 condi-tion,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 signifi-cantly,and distinct sidebands appear in the frequency domain.The dynamic load coefficients of the inter-nal 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 in-creases,the time-domain curves of contact force and angular acceleration exhibit multiple peaks,the side-bands in the frequency domain become denser,and the dynamic load coefficients of the internal and exter-nal 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 find-ings provide a theoretical basis for accurate diagnosis and dynamic simulation of compound faults in plan-etary gear transmission systems.关键词
