Abstract

Abstract: The traditional vehicle dynamics focuses more on numerical simulation, which separates from design model. LMS Virtual.Lab Motion - natively integrated in CATIA - is a multi-body dynamics package developed with CAA V5 for mechanical system, which is widely applied in engineering fields, such as aerospace, automotive, etc. But to expand to the dynamics of locomotive vehicle, the bottleneck problem of wheel/rail dynamic interaction should be solved. This paper employs CAA V5 and Motion UDF/UDS functions to create some special force elements which distinguish locomotive vehicles from general multibody system applications, and to integrate wheel/rail interaction solver module which determines wheel/rail contact locations and forces through hybrid programming of Fortran and C++. A simulation model for high-speed railway based-on CAD design model is built. Compared with Simpack, the analysis results of CRH2 reveal that the method is valid and available, and brings forward a new study way for CAD/CAE integration for high-speed railway.
