Abstract With the solution of Bessel function for equivalent circular cylinder conductor of rail, the current response of unit step voltage applied on rail was analyzed. Based on this solution, calculation method of skin effect in time domain with voltage step series was offered, and rail short-circuit model is build by S-Function with Matlab/Simulink. At last, this paper uses frequency calculation and short-circuits test to prove the validity of the calculation method.

Key words： Urban rail transit rail skin effect Bessel function step series
