煤矿铰接式双桥驱动物料运输车辆驾驶操纵设计

Driving control design of articulated double axle drive material transport vehicle in coal mine

为提升煤矿铰接式双桥驱动物料运输车辆驾驶操纵系统安全性,阐述了5t运输车驾驶室布置设计、操纵系统设计(柴油机启动和熄火、变速操纵、转向操纵、制动操纵、自卸操纵、操纵力确定)、辅助驾驶系统设计和人-机-环系统设计等关键技术。整车已批量应用到内蒙、陕西和山西地区不同生产能力的长距离缓坡斜井煤矿;车辆以常用速度30km/h行驶时,对驾驶室内部环境进行测试,最高温度为25℃,最大噪声为78dB(A);脉冲振动最大加速度为19.6m/s^(2),低于31.44m/s^(2),对人体无危害;随机振动最大加速度为0.312m/s^(2),小于0.315m/s^(2),驾驶员没有不舒适感觉;驾驶员持续驾驶2h无疲劳感,从未引发安全事故。整车驾驶操纵系统平均使用寿命为6a。

Aiming at the casualty accidents caused by the driving control system of articulated double axle drive material transport vehicle in coal mine, take 5 tons transport vehicle as an example, the key technologies of articulated material transport vehicle such as cab layout design, diesel engine start and stop, variable speed control, steering control, brake control, dump control, control force determination, assistant driving system design and design of man machine-environment-system were expounded. The vehicle has been applied to the inclined shaft coal mines with different production capacity in Inner Mongolia, Shaanxi and Shanxi. When the vehicle is running at the normal speed of 30 km/h, the internal environment of the cab is tested, the maximum temperature and noise in the test cab are 25℃ and 78 dB(A);the maximum acceleration of pulse vibration is 19.6 m/s~2, lower than 31.44 m/s~2, which is harmless to human body;the maximum acceleration of random vibration is 0.312 m/s~2, less than 0.315 m/s~2, the driver will not feel uncomfortable;the driver has no fatigue feeling after driving for 2 hours, never caused a safety accident. Mean life of the driving control system is 6 years.
