Mechanical Properties Analysis of Maglev Vehicle Suspension Mechanism

Abstract

In this paper, the suspension mechanism of maglev vehicle is selected as the research object, and the strength and fatigue life are analyzed after three-dimensional modeling, which provides the theoretical basis for the design, development and optimization of maglev vehicle. Firstly, the three-dimensional model of suspension mechanism of maglev vehicle is imported into Hypermesh to establish the finite element model of the whole suspension mechanism. According to the data provided by SMT, various load conditions are applied to the suspension mechanism. Then, the finite element model is imported into Ansys to obtain the displacement, stress and fatigue life contours under various working conditions. According to the analysis results of static strength and fatigue strength, the structure of the suspension mechanism can be optimized to meet the design requirements of strength and fatigue life finally.
