地铁齿轮箱吊座强度分析与疲劳寿命预测
Strength Analysis and Fatigue Life Prediction of the Subway Gear Box Bracket
摘要
Abstract
Through simulating and researching the force condition of gear box bracket, the strength analysis and fatigue life estimation for bracket are carried out by using ANSYS workbench, aiming at the related problems of strength, rigidity and fatigue life for subway gear box bracket. Through FEM simulation and strength analysis of bracket in two kinds of limited conditions, the deformation and stress nephograms of bracket can be obtained, which prove that the bracket satisfied the requirements of stiffness and strength. Finally, for alternating cycle load of the subway gear box bracket, the life of bracket can be estimated by making use of stress testing data in the paper, and it can privide a certain basis for preestimate maintenance and failure prediction.关键词
