摘　　要：针对目前井下轨道车辆机械式制动装置存在制动距离大、操作不方便的问题,采用液压制动系统方案对轨道车辆的制动性能进行研究.首先对井下轨道车辆液压制动系统的驱动结构进行设计,然后利用三维制图软件CATIA对液压制动系统的关键零部件——盘式制动器建立三维结构模型,并利用动力学仿真软件ADAMS对盘式制动器在不同摩擦系数状态下的制动性能进行仿真分析.研究结果表明,当摩擦系数为0.3和0.4时,采用液压制动的井下轨道车辆制动距离等参数都可以满足安全要求.In order to solve the problem of underground railway vehicle in coal mine,such as long braking distance and poor braking operation,hydraulic braking system was applied to the braking device of underground railway vehicle in this paper.Firstly,the driving mechanism of hydraulic braking of underground railway vehicle was designed.Later,CATIA software was used to design key parts of disc brake.Dynamic simulation software ADAMS was used to analyze dynamic performance of the modle under full load condition.The results show that when the friction coefficient is 0.3 and 0.4,the parameters such as braking distance of underground railway vehicles using hydraulic braking can meet the safety requirements.
