ANALYSIS OF WHEEL/RAIL TWO-POINT CONTACT BY USING FINITE ELEMENT METHOD

Abstract

Abstract: Based on the analysis of one–point contact of wheel and rail, the computational model for two-point contact resulting from cone-tread wheel flange close to rail is established. The prob-lems between wheel and rail are analyzed by using the finite element parametric quadratic programming. The results of the changing laws of wheel/rail contact states and force, which are obtained from computation of two-point contact problems be-tween wheel and rail carried out under various loads, would be helpful for finding methods for reducing wear of the wheel flange and side rail.

Key words: Finite element method, Parametric quadratic programming, Two-point contact, Wheel/rail contact force
