Abstract:A model of dynamic interaction between vehicles and tracks was established,and the corresponding program was developed.Then,the ride comfort evaluation method and index oriented to dynamic analysis of track alignment was compared and analyzed.Lastly,the effects of the minimum radius of circular curve and the minimum length of grade section on the ride comfort were investigated,and the reasonable ranges of the parameters were put forward.This research method and results of track alignment can be applied to defining track alignment design parameters and optimizing track alignment design,etc.

 

Key words: high speed railway; track alignment; ride comfort; dynamic simulation
