【Abstract】 This paper introduces the theory of geometrical contact between wheelset and rail. A system research work of the initial value influence on the fidelity of the numerical solution has been done. A new method to decide the initial value is brought forward. The geometrical contacts of the LM worn profile and the P60 rail, as well as UIC profile and S1002 profile are handled as examples.更多还原
