液气减速顶制动效率的研究

Research on Retard Efficiency of the Oil -Nitrogen Retarder

文章对液气减速顶对车辆的制动作用进行了研究。结合仿真结果，提出了制动效率这一概念，用以描述减速顶对车辆的制动综合效果，以期人们从减少回程功的角度得以提高减速顶的制动效率。文中正、反行程仿真计算结果与现场实验十分吻合，说明数学模型是足够精确的。

The thesis is the partial results of research concerning the retard action of the oil - nitrogen mixed retarder to the train. The definition of retard efficiency is put forward,which is used to depict the retard synthetical effect of the retarder to the train.
