摘要/Abstract

摘要： 传统的机车车辆动力学更多关注于数值仿真而与设计模型相脱离,LMS Virtual.Lab Motion是由CAA V5开发集成在CATIA环境中的多体动力学软件,在航空、汽车等工程领域得到广泛应用,但要拓展到机车车辆动力学尚待解决轮轨动态作用等瓶颈问题。为此,在集成于CAD的Motion坏境中,利用CAA V5和Motion的二次开发功能,自定义多个机车车辆特有力元,并结合C++和Fortran混合编程技术集成轮轨关系求解模块,构建了基于设计模型的高速列车动力学仿真分析模型。通过与Simpack中CRH2算例的定性分析对比,验证了方法的可行性,为其CAD/CAE集成提供了思路。

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.
