摘要
发展高速铁路是铁路现代化的必然趋势,也是我国客运走出困境的重大决策。因此,必须要以超前的专业基础理论的应用研究为后盾。为了探讨高速铁路垂向动态相互作用及其相关问题,本文以轮轨耦合系统动力学理论为框架,借助于垂向相互作用仿真系统 VICT,围绕高速铁路轮轨激扰控制、动态向应分析、机车车辆簧下质量限制以及轨道结构减振设计等几个方面的问题,展开了分析和论证,以期为高速铁路的设计和应用提供有益的参考。
It is a general trend to develop high—speed rail in order to modernize the railway industry.It is also a significant decision for Chinese railway to free itself from the current difficult situations.Its success relies on the application study of advanced basic theories. To address the issue of vertical dynamic interaction of wheel/rail on HS railway and other relative ones, this article provides analysis and proof in several ar- eas of HS railway within the frame—work of wheel/ rail contact system dynamics theory and in the light of Vertical Interaction Emulation System(VICT), including wheel/rail excitation control,dynamic re- sponse analysis,unsprung mass limit of locomotives and cars,and vibration reduction calculation of track structure.There issues are dealt with carefully in the hope of providing valuable reference to the construc- tion and application of HS railways.
