Contact Point Analysis for Wheel/Rail Contact Force Calculation

차륜/레일간의 접촉력 계산을 위한 접촉점 해석 알고리즘

In this paper, descibed was the derived algorithm for calculating contact point between wheel and rail and the developed method for rail modeling. The proposed methods use travelling distance to represent rail center line position vector and rail orientation with respect to Newtonian reference frame. The methods call be easily used ill multibody dynamic analysis. Two numerical examples are shown to verify the validity of the proposed methods.
