摘要
对滤波减速器的结构原理及多齿弹性啮合效应进行了介绍,借助显式动力学软件ANSYS/LS-DYNA建立了其三维有限元非线性接触分析模型,对齿轮传动机构在一定转速和不同负载转矩下进行了动态啮合仿真,得到了多齿接触情况下齿面接触应力、齿根弯曲应力分布以及接触合力随时间变化规律,该方法可以进一步为滤波减速器齿轮强度分析和疲劳寿命计算提供理论依据。
The filtering reducer structure principle and multi tooth elastic meshing effect are introduced,with the help of explicit dynamics software ANSYS / LS- DYNA,the three- dimensional nonlinear finite element contact analysis model is established,the dynamic meshing simulation of gear transmission mechanism under a certain speed and different load torque is carried out,the tooth surface contact stress,tooth root bending stress distribution and the rules of contact force changes under the condition of multi tooth contact with time are obtained,a theoretical basis for further filter reducer gear strength analysis and fatigue life calculation is provided by this method.
