分析了城际列车牵引性能的特点和技术难点,讨论了160km/h和200km/h两种速度设置的必要性及各自的特点。重点分析了牵引系统中牵引力、加速度、牵引功率、转矩、转速及齿轮传动比之间的函数关系。在此基础上,初步选择不同牵引系统平台的两种速度牵引系统的设备参数。通过牵引特性和仿真计算,验证了所选牵引系统设备的性能能够满足加速性能指标的要求,并验证了故障情况和救援工况时的性能能满足运用要求。

Characteristics and technical key points of the traction performance for intercity electrical multiple units（EMU） are analyzed based on the project demands and resource.Two kinds of train speed-160 km/h and 200 km/h,their characters and necessities are studied,especially the relationship between traction effort,acceleration,traction power,torque,velocity and gear ratio in the traction system are analyzed.On this basis,the major parameters for traction devices are chosen for the two different traction platforms.Finally,through calculation of the traction characteristics and simulation,the acceleration performance of the chosen traction platform is verified,it could satisfy the index requirements,even in fault and rescue situations.
