高速列车耦合大系统动力学及服役模拟
|
摘要
根据高速列车运行、服役的特点及动力学研究的需求,以高速列车为研究对象,提出了与线路、接触网和气流耦合作用的高速列车耦合大系统动力学理论框架.采用子结构方法,通过运动或力的耦合,构建了高速列车耦合大系统模型.从运行安全性和可靠性出发,提出服役模拟的概念,论述了高速列车服役模拟研究的必要性,并对材料、结构和参数等失效模型的建立,以及服役模拟的过程、方法和研究内容提出了建议.
A theoretical dynamics framework for the general coupling system of high-speed trains was proposed according to the operational features of high-speed trains and the demand to study dynamics of the high-speed train system.In the framework,the track,catenary and air flows are coupled with the high-speed train.A model for the general coupling system was built with substructural method,where the substructures are coupled by forces or movements.A concept of service simulation and its necessity were discussed to improve the operational safety and reliability of high-speed trains.Suggestions on failure modeling of materials,structures and parameters,as well as the procedure,method and research scope of service simulation,were presented.
