"Important part of the wheelset movement modelling is the estimation of the contact forces. In this paper algorithms used for contact force calculation are compared on a simple case of wheelset placed with varying lateral displacement. Results revealed that methods based on Hertz contact provide some unwanted step changes when the flange touches the rail. On the other hand the CONTACT algorithm gives continuous raise of the contact forces. This makes it more suitable for simulations of wheelset movement."@en . "Jandora, Radek" .
