The methods of vibration fatigue stress simulation and strength evaluation under stationary
state are quite complete, but the research on vibration fatigue under non-stationary state is …

This paper investigated on the high frequency vibration-induced fatigue failure of antenna
beam through both field tests and numerical simulation. In the field tests, the dynamic stress …

The axle box ASD (Acceleration Spectral Density) spectrum serves as the main resource of
high frequency vibration for rail vehicles, which is usually taken as a critical load spectrum …

The fatigue failure of anti-yaw damper seats on the carbody of railway vehicles is found
during operation. The load time histories were obtained through calibration tests and field …

In order to explore the causes for failure of connecting bolts between the axle box front cover
and axle box body on high-speed train, field test was carried out firstly in this work. The …

It has been previously noted that the development of aerospace material technology and
