摘要:为研究偏心故障对双齿圈人字行星传动系统动态接触力均载特性的影响规律,基于 SolidWorks和ADAMS构建系统相应的虚拟样机模型,对无故障系统和太阳轮存在不同程度偏心故障的系统进行仿真分析,以均载系数为主要评价指标,分析系统不同状态下的均载特性。通过仿真分析,提出一种在系统中添加柔性支撑的方法,改善偏心故障造成的系统不均载问题。结果表明,无故障状态下,系统内外啮合副接触力时域曲线均呈周期性变化。随着偏心程度增加,均载系数呈增大趋势。系统存在偏心断齿故障时,接触力时域曲线出现明显的故障特征,内、外啮合副的均载系数较无故障时的值分别增加12.1％和14％。存在偏心点蚀故障时,各啮合副接触力呈正弦波变化,故障特征比偏心断齿故障更具有规律性,内外啮合副的均载系数均增加了5.6％。添加柔性支撑后,系统接触力的分布更加均匀,很大程度上解决了系统偏心故障问题并改善了系统的均载特性。研究结果可为改善系统动力学特性、故障诊断研究和系统动态设计提供依据,具有一定的工程实践意义。

Abstract: In order to study the influence of eccentricity failure on the dynamic contact force and load sharing characteristics of the double-ring herringbone planetary transmission system,a corresponding virtual prototype model of the system was constructed based on SolidWorks and ADAMS. The system was simulated and ana lyzed,and the load sharing coefficient was used as the main evaluation index to analyze the load sharing characteristics of the system under different conditions. Based on simulation analysis,a method of adding flexible support to the system was proposed to improve the uneven load of the system caused by the eccentric fault. The results showed that the time-domain curve of the contact force of the internal and external meshing pairs of the system changed periodically. With the increase of the eccentricity,the load factor showed an increasing trend. When the system had an eccentric broken tooth fault,the time domain curve of the contact force had obvious fault characteristics. The load sharing coefficients of internal and external meshing pairs were increased by 12. 1% and 14% respectively compared with no fault. When there was an eccentric pitting failure,the contact force of each gearing pair changed in a sine wave,the fault characteristics were more regular than the eccentric broken tooth fault,and the load sharing coefficients of internal and external meshing pairs had increased by about 5. 6% . When the flexible support was added,the distribution of the contact force of the system was more even,the problem of system eccentricity fault was solved to a great extent and the load sharing characteristics of the system were improved. The results provided a basis for improving the system dynamics characteristics,the fault diagnosis research,and for realizing the dynamic design of the system,and had certain engineering practical significance.
