车辆动力学的研究和发展

Recent Research and Development onVehicle Dynamics

随着轮／轨相互作用研究的深入，铁道车辆动力学问题需要把车辆／线路视为不可分的整体系统。由于研究中需要考虑某些部件的弹性，从而导致高频动力学的发展。理论研究和模拟软件为新型结构设计和车辆安全性检验提供了廉价工具，但试验技术仍然是不可缺少的最终手段。本文根据国际车辆系统动力学协会（ＩＡＶＳＤ）第十三届学术会议上所发表的论文，介绍了上述主题的概况，在此基础上，提出对我国车辆动力学研究课题和发展方向的建议。

With the deepening of research in wheellrail interaction,vehicle dynamics demandsthat vehicle/track be regarded as an inseparable integral system.Since the elasticity of somecomponents must de consider in the research work,high frequency dynamics has made greatadvances,Although theoretical results and simulation programs have provided low-price toolsfor the design of new constructions and vehicle safety assessment,testing techniques remainindispensable final mediums.This paper introduces the gist of the above subjects as are ex-pounded in some articles whichare published in“ Dynamies of Vehicles on Roads andTracks”by the 13th International Association for Vehicle System Dynamics(IAVSD).Onthis basis proposals are put forward here about the direction of development and subjects ofresearch on vehicle dvnamics in China。
