Influence on the locomotive curve passing performance with wheel tread shape;

The interaction between wheel and rail results in the severe damage of the wheel tread,which is a problem that has not been resolved yet.

On this basis, a kind of automatic test technique in service of railroad wheel surface is presented.

The procedure of smoothing wheel profile can be realized by GUI interface with loop,the assessment of roughness,the filing treatment and re-assessment of roughness.

Prognostics for surface scrapes on wheels based on integrated rough neural network;
