Abstract

Abstract

A particular finite element analysis model of subway vehicle car body structure was set up with finite element method and ANSYS software, tow truck was taken as analytical object according to subway vehicle load and dangerous grade, the FEM calculational loads, constant operating conditions and assessing standards of the model were confirmed, subway bodywork static strength under all-setup and its inherent frequencies and vibration model were reckoned. The result indicates that the static strength of subway car body structure satisfies the relative design requirements in constant operating conditions, at the same time, its first step torsion and vertical bend vibration frequencies are smaller than 10 Hz, which is overall bogie pitching frequency. It is pointed that reducing its secondary vibration frequency can improve its primary vibration frequency and alleviate body mass by improving stiffness while decreasing structure mass.
