摘　　要：多轴特种车辆的操纵稳定性是其机动性能的关键性能指标,而且是保证车辆安全的前提。在UG中建立某8轴车辆三维模型,将三维模型导入ADAMS,建立整车动力学模型。基于预瞄-优化理论,在Fortran语言环境下建立驾驶员模型,嵌入到ADAMS中实现人-车-路闭环的控制系统仿真。根据所建立的模型,分别进行转向盘角阶跃输入、双移线和蛇行的车辆操纵稳定性仿真,仿真结果表明,驾驶员模型能够有效地控制车辆位置和速度进行轨迹跟踪,整车的操纵稳定性较好。The handling stability is the key characteristics as to maneuverability of vehicle.The CAD model of eight-axle vehicle is built in UG and imported into ADAMS.The driver model is built with Fortran language based on Preview-optimal theory,and the closed-loop model of driver-vehicle-road is set up.The simulations of vehicle handling stability are made including open-loop test simulation such as steering-wheel angle step input test,closed-loop test simulations such as double-lane change maneuver and hunting maneuver.The simulation results have proved that the Preview-optimal driver model can control the vehicle's position and velocity effectively,and the vehicle has got a better handling stability performance.
