In order to reduce the wheel profile wear of highspeed\ntrains and extend the service life of wheels, a dynamic\nmodel for a high-speed vehicle was set up, in which the\nwheelset was regarded as flexible body, and the actual measured\ntrack irregularities and line conditions were considered.\nThe wear depth of the wheel profile was calculated by the\nwell-known Archard wear law. Through this model, the\ninfluence of the wheel profile, primary suspension stiffness,\ntrack gage, and rail cant on the wear of wheel profile were\nstudied through multiple iterative calculations. Numerical\nsimulation results show that the type XP55 wheel profile has\nthe smallest cumulative wear depth, and the type LM wheel\nprofile has the largest wear depth. To reduce the wear of the\nwheel profile, the equivalent conicity of the wheel should not\nbe too large or too small. On the other hand, a small primary\nvertical stiffness, a track gage around 1,435ââ?¬â??1,438 mm, and a\nrail cant around 1:35ââ?¬â??1:40 are beneficial for dynamic performance\nimprovement and wheel wear alleviation.
