摘　　要：针对传统地下运输车辆制动效能波动明显,系统稳定性差等问题,将湿式制动器引入传统地下无人车辆制动系统,并对湿式制动系统最主要评价指标带排转矩进行计算与仿真研究,得到系统在不同体积流量、动力黏度和沟槽类型条件下制动系统带排转矩的变化规律。分析结果表明:随着制动系统供油量增多,各类湿式制动器摩擦盘模型带排转矩均呈现增加趋势;供油量变化对径向油槽产生的带排转矩影响相较螺旋油槽与华夫油槽明显;高速、相同外界条件下,径向油槽产生的带排转矩明显高于螺旋油槽与华夫油槽。In view of the problem of the braking effectiveness obvious fluctuation, poor system stability of traditional underground transport vehicle, the wet brake is introduced to the traditional underground unmanned vehicle braking system, the calculation and simulation study of the drag torque which is the main evaluation index of wet brake system is carried out, and the change rule of the braking system drag torque under the condition of different oil supply quantity, oil viscosity and groove type is got. The results show that, with the increase of the oil supply quantity of braking system, the drag torque of all kinds of wet brake friction disk model show an increase trend ; the influence of the oil supply quantity change on the drag torque generated by radial oil grooves is more obvious than the spiral oil groove and waffle oil groove ; under the condition of high speed, the same external condition, the drag torque generated by radial oil groove is obviously higher than that of the spiral oil groove and the waffle oil groove.
