Abstract

The field of railway engineer has been one important part of multibody dynamical simulation since early years. The significant advantage of multibody approach on satisfying calculating effort enable the numerous engineering application. It has been nowadays recognized as a reliable and mature computer aided engineering tool. In railway dynamics simulations, creep forces determination is an crucial issue. An adhesion model to increase the accuracy of determining creep forces is the pursuit of many numerical studies in this field. It is challenging to obtain an accurate adhesion model because the adhesion phenomenon occurs in the interface of wheel-rail contact, and the wheel-rail contact is an open system, which is affected by rather complex factors. This paper is going to present an extension of the adhesion modelling for multibody system dynamical simulation, which is able to consider the influence of the environmental temperature.
