主　　题：wheel wear intercity train motor car and trailer finite element method(FEM) field test 

摘      要：To analyze wheel wear discrepancy between motor car and trailer of an intercity train,a novel wheel wear rates calculation model was proposed,which was composed of the intercity train dynamics model,wheel-rail three-dimensional rolling contact FEM model and the wear *** simulated results were contrasted with measured results in field *** simulated results showed the motor car wheels had larger rotation rate and longitudinal creepage than the trailer ***,the motor car wheels encountered larger vertical forces and longitudinal forces from bogie because of the heavier car body and the impact of traction *** traction torque acting on motor car wheel could increase the slip rates in the rear part of wheel contact patch and weaken the spinning phenomenon of relative *** contact pressure and slip rates caused the higher wear rates of motor car wheel than those of trailer *** overall trends of wheel wear depth in simulated and tested results were *** they both showed the motor car wheel encountered the more serious wear than the trailer *** models can be used to study the effect of the traction characteristics curves on the wear of wheel.
