摘　　要：分析了铁路进一步提速对机车牵引动力的要求,从改善机车在既有线路运行时的动力学性能及曲线通过性能出发,对200km/h机车(C0-C0轴式)一系簧有关刚度进行分析计算,认为应使中间轴一系簧垂向刚度小于端轴。It is analyzed the requirement of further speed-up of railways on the locomotive traction force. Starting from the improvement of dynamic performance and curve negotiation performance on existing lines, analysis and calculations are made to the stiffness of the primary spring of 200 km/h locomotive. It is suggested that the vertical stiffness of the mid-axle should be lower than the end axle.
