Abstract

In order to analyze the dynamic performance differences of light rail transit (LRT) under different marshalling, this paper establishes the nonlinear system dynamics models of three-module marshalling, six-module marshalling and twelvemodule marshalling low-floor LRTs, and then analyzes the dynamic performance of the vehicle under straight lines and curves. The results show that in the straight line, the vehicle of the three modules is in the range of 20km/h ~ 70km/h, and the difference of the stability index and the safety index is very small, and all meet the standard requirements. Under the curve line, the difference between the three modular marshalling types is very small in the range of 20km/h ~ 60km/h, and the twelve modular marshalling vehicles are slightly larger than the other two types. From the perspective of the critical speed of the vehicle, the critical speed difference between the three-module marshalling vehicle and the other two marshalling vehicles is small, only 5km/h. Under the calculated line condition and speed, there is no significant difference in vehicle dynamic performance.
