Abstract

Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, Ahead of Print.
Aiming at the vertical abnormal vibration problem of a new type of rail vehicle bogie frame, through line test and theoretical analysis, it is revealed that the root cause is the poor transmission relationship of primary suspension system. The vehicle ...
