万吨列车缓冲器特性优化研究

Research for Buffer Gear Characteristic Optimization of Heavy- haul Train

以新型胶泥缓冲器为例，建立列车纵向动力学仿真模型，根据其结构与原理详细分析该类型缓冲器的力-位移、力-速度特性。通过单车模型中多次仿真与试验曲线相比较，反演出缓冲器特性曲线，将该曲线应用于万吨列车模型并进行优化，从而得出重载列车最佳缓冲器特性曲线。

Based on the new plaster buffer, This paper established the train longitudinal dynamics simulation model.According to it＇s structure principle, it analyzed the forces - displacement and forces - speed character of this hitler in detail. By means of multiple comparison between simulation curve and experiment curve in single vehicle model, a characteristic curve of buffer was found out, and this curve in train model was applied to optimize characteristic curve, finally the best buffer characteristic curve for heavy- haul train was found out.
