转K7型转向架副构架疲劳强度分析
Fatigue strength analysis of deputy frame of K7 bogie
摘要
Abstract
A three-dimensional model of deputy frame of K7 Bogie was established by using the finite element software of ANSYS11.0. Combined with the force characteristics, the stress distribution of the deputy frame was analyzed and calculated. According to the measured load spectrum of rods of deputy frame and S-N curve of B + grade casting steel in different defects factor, and with the help of finite life design theory, the fatigue life of deputy frame, which met the practical application requirements, was finally predicted.关键词
