Abstract

Computation of contact points between the wheel and rail is a fundamental problem in dynamic simulation of trains. For this purpose, an accurate model of a switch surface is needed. The objective of this study is to develop a mathematical model for a switch. The model for the switch will be based on skin surface scheme whereby a number of profiles will be place along a track curve. Each profile will be divided into segments of similar shapes. Then, each set will be used in an interpolation scheme to generate the switch surface.
