摘　　要：高速铁路不仅是列车运行速度的简单提高,还应重视线路舒适性的全面提升。面向高速铁路线路设计阶段,基于现有数字化选线设计研究成果,应用车辆-线路耦合动力学理论,结合列车运行仿真技术,对设计方案进行全程动力学仿真计算,实现了线路设计方案舒适性的仿真分析研究,为舒适度实时动态评价奠定基础,并为基于舒适性评价的线路设计方案优化提供理论依据。基于上述研究的理论与方法,研发了高速铁路舒适度评价系统,辅助设计人员检测出线路设计方案中的舒适性缺陷路段并提出改进措施,提高线路设计质量,保证了高速列车运行的乘坐舒适性。The high speed railway means not only a simple raising of train running speed, but also a comprehensive up- grade of the line comfort. Facing the design stage of the high speed railway, based on the existing research results of railway alignment design, and by applying Vehicle-Track Coupling Dynamics theory, combining with the train running simulation technology, the whole dynamics simulation calculation was conducted for the design scheme, which realized the simulation analysis research of the track design scheme comfort and laid the foundation for read-time dynamic evalua- tion of comfort, and provided a theoretical basis for optimization of railway design scheme based on comfort evaluation. According to the above research theories and methods, A comfort evaluation system for high speed railway was devel- oped, and the assistant designers has detected the sections with comfort defects in railway design scheme, and has put forward the improvement measures. Thus the design quality of railway was improved and the ride comfort of the high speed train was guaranteed.
