摘要
针对行星齿轮传动系统在实际应用过程中经常由于共振而导致传动系统出现故障的问题,利用三维参数化建模软件PTC Creo Parametric建立了行星齿轮传动系统的实体模型,并装配成虚拟样机,应用ANSYS对行星传动系统进行模态分析,得到其固有频率及各阶振型,分析其振动特性;并考虑系统的啮合刚度,进一步研究对比ANSYS中不同接触算法对系统振动特性的影响,为行星传动系统齿轮精确模态分析提供了一定的参考和依据。
Aiming at the failure problem of planetary transmission system due to the resonance in the process of actual application,the virtual prototype of modified planetary transmission is established by using the parametric modeling techniques in PTC Creo Parametric. The dynamic modal analysis is done in virtue of finite element model of the planetary gears in ANSYS. The natural frequency and corresponding vibration mode are obtained,and the vibration characteristic is analyzed. The meshing stiffness of the system is considered,and the influence of the different contact algorithms on the vibration characteristics of the system is studied. It can provide reference and basis for the accurate modal analysis of the planetary transmission system.
