摘　　要：以NTE190矿用自卸车操纵稳定性为研究对象,在Trucksim中建立整车多运动场仿真模型,将方向盘转角及前轮定位参数作为整车模型的输入值,通过对车辆模型的固定转向盘稳态回转试验和紧急双移线试验的仿真,分析整车的操纵稳定性,并与ADAMS单场建模优化分析方法进行对比,验证Trucksim多场建模分析方法的优越性与可靠性。结果表明该种仿真分析方法具有良好的应用优势,为此类矿用自卸车操纵稳定性的研究提供重要的研究方法,可以应用于实际设计生产和相关系统优化设计。Handling stability of NTE190 mining dump truck is studied. Simulation model is established in Trucksim, such as steering angle and wheel alignment parameters as input values. Through the simulations of vehicle steady circular test infixed steering wheel and emergency double lane change test it analyzes each optimization＇s vehicle handling stability. And with a single field optimization ADAMS verified by comparing the advantages and reliable multi-line Trucksim field modeling analysis method, simulation analysis shows that this kind of method has the advantages of a good application, and provides important research method for this type of vehicle handling stability study which can be applied to practical design and production.
