矿区道路线形参数对矿山运输车辆行驶稳定性的影响研究

The influence of road line parameter on driving stability of transport vehicles in mining area

矿区道路线形差异较大,运输矿产的车辆多,因此,不合理的矿区道路线经常引发严重的道路交通安全问题。车辆的行驶过程是驾驶人通过对道路线形的观察、判断、预测、综合处理所获信息后对车辆做出适度操作,并根据车辆响应实时修正的闭环过程。在乘用车动力学分析及模型建立的基础上,借助CarSim车辆动力学仿真软件,研究不同的矿区道路线形几何参数对矿山运输车辆行驶稳定性的影响。在此基础上,获得道路线形几何设计参数的合理取值范围。研究成果将为道路几何线形设计参数研究提供理论依据和技术支持,为改善矿区交通安全提供参考。

Road line in mining area is quite different,and there are many vehicles which transport mineral products,so irrational road line of mining area often leads to severe road traffic problems.The driving process is a closed-loop process that drivers make moderate operations to vehicles after achieving information by means of observation,judgment,prediction,synthesized treatment to road line and make real-time correction according to vehicle response.Based on the dynamic analysis of passenger vehicles and model construction,this paper studied the influence of different geometrical parameters of road line on the driving stability of transport vehicles in mining area by CarSim vehicle dynamics simulation software and endeavored to obtain the reasonake value range of geometrical design parameter of road line.The research results will provide theoretical basis and technical support for designing parameter of road geometrical line as well asprovid references for improving traffic safety of mining area.7figs,6refs.
