摘要： 基于ADAMS/CAR建立了某车辆虚拟样机模型,分别对二轮转向下,无制动、后内轮制动及四轮全制动三种情况下的运动特性和受力特性进行了比较分析.结果表明,在后内轮制动与四轮全制动情况下,转弯具有较好的稳定性和路径跟踪性.对车辆动态控制与四轮转向集成、无制动四轮转向及二轮转向进行了对比分析.仿真结果显示,车辆动态控制与四轮转向集成控制不仅可以保证高速转向的稳定性,同时高速转向的灵活性也得到了提高,这对减少高速行驶时道路交通事故的发生具有重要意义.

Abstract: Based on ADAMS/CAR a virtual four-wheel steering (4WS) car prototype was developed, then its kinematic characteristics and forced conditions were analyzed in cases of two-wheel steering (2WS) without braking, with rear left wheel braking and four-wheel braking. The results indicated that the steerability is more stable and trackable during rear left wheel braking and four-wheel braking. A comparative analysis was made between the VDC (vehicle dynamics control) integrated with 4WS, 4WS without braking and 2WS, and the simulation results revealed that the steering stability at high speed are ensured by the VDC integrated with 4WS with flexibility improved. The conclusion is important to reduce traffic accidents for cars at high traveling speed.
