The loads for bogie frame fatigue damage prediction under service environment has become a critical priority. In this study, the completeness of the measured loads was verified and bogie loads were classified into quasi-static and dynamic regions. Bogie modal vibration and rail corrugation were studied to adjust the loads. The predicted fatigue damage was closer to the actual damage and covered the measured damage. The results of this study showed that the service loads of existing frames and their characteristics can be used to predict the damage suffered by similar type of frames under similar application conditions.

基于实测载荷的地铁转向架框架疲劳损伤预测

使用环境下转向架框架疲劳损伤预测的载荷已成为一个关键的优先事项。本研究验证了实测载荷的完整性，并将转向架载荷分为准静态和动态区域。研究转向架模态振动和轨道波纹以调整负载。预测的疲劳损伤更接近实际损伤并覆盖了测量的损伤。研究结果表明，现有框架的使用载荷及其特性可用于预测相似类型框架在相似应用条件下遭受的损坏。
