Abstract:In present study, the aerodynamic fatigue behaviour of train equipment cabin was investigated. Pressure sensors were arranged at train passing side. Eight‐grade load spectrum was constructed by means of rain‐flow counting, and fatigue damage was calculated with Miner''s rule and Carten‐Dolan rule, both for the matrix metals and welds. For welds, defect detection was considered via visual inspection with nondestructive test (VI‐NDT), pure nondestructive test (P‐NDT), and without nondestructive test (W‐NDT). The result confirms that welds play an unfavourable role rather than matrix metals. Weld damage in W‐NDT exceeds its limit (1.0) to designed mileage. Then, damage influence was studied under tunnel passing, train passing, and running direction. Running direction as the head car contributes 82% to approximately 86% and 70% to approximately 77% of the total damage for matrix metal and welds, respectively. Train passing gives more damage to matrix metals than welds. Tunnel passing contributes 25% to approximately 26% for both matrix metals and welds.
