Resonance-corrected equivalent load reconstruction for fatigue assessment of metro bogie frames
Qingwei Song, Chengjie Wang, 李春来, Yunpeng Wang et autres
Abstract To address the distortion of measured load signals in metro bogie frames caused by wheel-rail excitation-induced modal resonance under service conditions, field tests and signal analyses were conducted. The results show that external excitations induce modal resonance, with dominant frequencies at …
