The classical mathematical models and the corresponding multibody programs are not always adapted to the increasing diversity of railway bogie designs, since the most general envisaged case consists of a carbody (or several) carried by two rigid bogies equipped with wheelsets. Although the latter configuration still represents the major pan of the railway vehicles in use, new concepts in the design of bogies (independent wheels. articulated frame, pneumatic suspensions,…) have a relatively poor scientific background with respect to the know-how gained in the domain of conventional vehicle : this justifies the development of more general mathematical modelling and computer programs, able to generate a reliable model in a relatively shon time. The multibody program ROBOTRAN has been developed in that sense, offering the possibility to obtain the models of a family of railway vehicles-conventional or not-from a symbolic library of carbodies and bogies. The present paper illustates this through a comparison of behaviour between three bogies in a same situation : the envy curving at constant speed.
