摘要

介绍了GCY300II 型轨道车转向架构架结构特点，采用TB/T 1335 — 1996 对该构架进行静强度仿真及动应力试验，并进行对比分析，验证仿真模型的正确性。就构架焊接工艺性差的问题提出结构改进方案，对比分析结构改进前后的静强度仿真计算结果。计算分析结果表明：结构改进前后的强度均满足铁标规范要求，改进方案更合理实用。

Abstract

GCY300II rail car bogie frame structural features were described. With TB/T 1335 — 1996, simulation framework for static strength and dynamic stress test were carried out, and correctness of the simulation model was verified by comparative analysis. Based above, structure improvement was proposed for poor welding on the frame, and static strength simulation results was compared before and after the improvement. The results showed that structural strength of bogie frame before and after improvement both met rail standards’ requirement, but the improved was more reasonable and practical.
