Matching performance of CHN60N rail with various wheel profiles for Chinese high-speed railway
Abstract
The matching of wheel profile with rail profile is the key issue in design of high-speed railway, it directly affects the vehicle dynamics performance during travelling and the wear behavior of wheel/rail. The matching performance of wheel profiles LMA, S1002CN and XP55 widely used in Chinese high-speed railway with CHN60N rail was analyzed in the study in terms of wheel/rail contact geometry, wheel/rail rolling contact and vehicle-track coupling dynamics. The results indicate that: By comparing the matching performance of the three wheel profiles with CHN60 rail, S1002CN profile matches best with the CHN60N rail. XP55 profile is not applicable to CHN60N rail.
