Modal Analysis of Gear Transmission System Based on ANSYS

Abstract:

With the study of a certain servo gear transmission system, a three-dimensional parametric design of servo drive system is made based on SolidWorks and its plug-in GearTrax. The model is introduced into ANSYS through a special interface, and the finite element modal solutionsare obtained. Aiming at solving the practical problem that the static linear modal analysis methods fail to meet the working conditions of high speed rotation and frequent variable speeds, this paper proposes an effective way of determining the range of the system natural frequency through figuring out the natural frequencies in two critical states. Thus, it provides an important basis for the credible design of the servo drive system and a reliable theoretical guidance and reference data for its design, use and maintenance.
