摘　　要：以缩短矿用电机车制动系统响应时间、提高轮轨黏着系数利用率为目的,对5 t矿用电机车原有的手轮闸瓦式制动系统进行了改进,采用液压盘式制动器,并且安装了制动防抱死系统。利用AMESim系统仿真软件建立了单轮车辆制动仿真模型,对电机车在不同黏着系数的常规制动系统和防抱死制动系统的制动性能进行分析,结果表明,防抱死制动有利于提高轮轨间黏着系数利用率,进而缩短电机车的制动时间和制动距离;利用ABAQUS有限元仿真软件,建立了盘式制动器有限元模型,进行温度场分析,结果表明,随着轨道摩擦因数的增大,制动盘最高温度增高,温度场分布越不均匀,但是盘式制动器最高温度值未达到150℃,满足规定要求。In order to shorten the response time of mine electric locomotive braking system and improve the utilization ratio of wheel rail adhesion coefficient, the original handwheel brake shoe type braking system of 5 t mining electric locomotive is improved. The hydraulic disc brake is adopted, and the brake anti lock system is installed. A single wheel vehicle brake simulation model by AMESim simulation software, analysis resuhs show that the braking performance of motor vehicle under different adhesion coefficient of conventional braking system and anti lock braking system, ABS can improve the wheel rail adhesion coefficient utilization rate, and shorten motor vehicle braking time and braking distance. By using the finite element software ABAQUS, establish the finite element model of disc brake, temperature field analysis results show that with the increase of rail friction coefficient, the maximum temperature of the brake disc is increased, the temperature distribution is not uniform, but the disc brake did not reach the maximum temperature of 150℃, meet the requirements.
