Open publisher page 0 citations

Abstract

Based on the structure and load characteristics of CW-200K bogie frame,using solidwork method,the physical model for the frame was built and the finite element analysis on the model was performed.Refering to JIS E 4207 standard and Goodman sketch for welding materials,the fatigue strength of the frame is checked with a good result.This analysis provides foundation for establishing design specifications and test standards for trains used under Chinese line conditions.Using CAD/CAE to analyze CW-200K bogie frame can not only reduce the work laod,but also make the results more precise.
