Abstract
In this investigation, a numerical procedure that accounts for multipoint contact for the analysis of vehicle/turnout interactions is developed. To this end, the multiple look-up contact table approach that can be used for modeling the change in the rail cross sectional shapes on turnout along the track is generalized for multipoint contact scenarios. The numerical results are compared with those of the online constraint/elastic contact approach for the analysis of curve negotiation first, and then it is demonstrated that the numerical procedure developed in this investigation can be used for predicting the multipoint contact between the wheel and rail for the analysis of vehicle/turnout interactions.
