The Elastic Dynamics Simulation Analysis of Cylindrical Helical Gear Transmission

基于有限元法思想,建立了系统的有限元模型,以机械系统动力学理论为依据,建立系统振动方程,分析系统的动态激励。在ANSYS Workbench环境下对系统进行模态分析,得到了系统的固有频率和振型;进行系统的动力学瞬态仿真,得到了系统的动态响应。为斜齿圆柱齿轮传动系统的动态性能研究、动态强度计算、轮齿的修缘设计等提供理论基础。

The system of finite element model was built on the base of the finite element method thought. Further, according to mechanical system dynamics theory, the motion equation of the system was built. And the analysis of system dynamic excitation was made. In the Ansys workbench environment the system of modal analysis was made, and the natural frequency and vibration mode was obtained; by means of the establishment of the system dynamic transient simulation, the dynamic response of the system was achieved. So, a theoretical basis is provided, for the dynamic performance of the system under study, the dynamic strength calculation and gear rim design
