摘要：

In the domain of railway dynamics, specific models have been developed based on Hertz and Kalker theory to calculate the normal and tangential stresses in a semi-analytic way, and inserted into multibody codes, in order to ensure fast and reliable simulation of the contact stresses in the presence of dry friction. Recently several advanced contact models have been developed which are able to manage non-Hertzian simulations online. The particular developments proposed by the authors are presented.
