The Development of Program for Time Domain Simulation of Railway Dynamics

철도차량 동역학의 시간영역 시뮬레이션 프로그램 개발

The algorithm for relation of contact status, track shift, and contact force caused from wheel/rail contact geometry is presented. Grafting this algorithm into a algorithm of general program analyzing mechanical system, the program for time domain simulation of railway vehicle dynamics, called CASOTD, was developed. In addition, as applied example of CASOTD, the dynamic simulation of railway vehicle running on a rail joint and a irregularly alinemented rail is done in this paper.
