Abstract
Description
technical field
[0001] The invention relates to a comprehensive simulation method for the dynamic performance of a train and line system. Background technique
[0002] The running of a rolling stock on a track is a process of dynamic interaction between a moving mass system and an infinitely long continuous support structure. Due to the unevenness of the line, the geometric defects of the wheel and the rail surface, etc., there is an interaction force between the wheel and the rail. This force is transmitted upward to the rolling stock and downward to the track structure, causing respective vibrations, and these vibrations are coupled with each other to form a coupling system between the rolling stock and the track. It is this complex relationship that makes the dynamic operation system of the train on the line have the characteristics of multiple degrees of freedom and strong nonlinearity, which makes the system very complicated.
