| 摘 要： | 近年来,高速铁路在我国得到了快速发展,由高速列车引起的线、桥振动问题越发突出.针对客运专线车-线-桥系统的特点,利用有限元方法建立了车辆一无砟轨道-桥梁耦合模型.鉴于模型的复杂性,将该模型分为列车一无砟轨道系统和无砟轨道-桥梁系统两个子系统来研究,两个子系统通过轮轨相互作用力耦合.根据Hamilton原理,可推导出两个...

| Abstract: | The high-speed train system provides us a swift communication.But the dynamic behavior of bridg-es caused by high-speed trains has become an important issue.Aiming to the vehicles-track-bridge dynamical characteristics of passenger-lines,based on the previous literatures,the finite-element model of vehicle-unbal-last track-bridge is proposed.Because of the complicity of the whole model,in this papert,wo subsystems are investigated.The first subsystem is vehicle-unballast track model.The second subsystem is ... |
