...Jialong Hu; Boyang An; Yu Chen; Ping Wang Purpose In vehicle-track coupled dynamics, the wheel-rail contact model is particularly important because its accuracy and stability determine the effectiveness and reliability of the vehicle-track coupled model. The aim of this article is to propose...

.... The purpose of this paper is to obtain a better agreement with the experimental behavior by presenting a 3D generalized rigid particle contact model based on a multiple contact point formulation, which allows moment transmission and includes in a straightforward manner the effect of friction at the contact...
