Modal analysis of planetary gear train based on ANSYS Workbench

Robots have been widely used in the fields of automobile, mechanical processing, electronic and electrical, food industry and so on. It plays an important role in modern society. The realization of the robot's motion depends on the precise gear transmission, so the research of the planetary gear in the robot is particularly important. This paper takes the planetary gear train as the research object, determine the parameters of each component of the planetary gear train, three dimensional models of the planetary gear train based on SolidWorks2014. The dynamic modal analysis of the planetary gear train is carried out by the finite element software ANSYS Workbench. The vibration modes and frequencies of the planetary gear trains are obtained by modal analysis, the resonance region in the design of the planetary gear trains can be avoided by analyzing the results, avoiding resonance damage to the planetary gear structures and the foundation for further dynamic analysis of the planetary gear train is established.
