四轮转向车辆的操纵稳定性分析OA北大核心CSCDCSTPCD
Analysis of Vehicle Handling and Stability of Four Wheel Steering
针对四轮转向(4WS)车辆的操纵稳定性问题,以线性二自由度车辆模型为基础,从时域和频域两个角度分析了如何通过控制后轮转角相位与角度来提高4WS 车辆的低速机动性和高速稳定性。用0.4g 的侧向加速度来界定四轮转向系统的有效工作区域,推导出后轮转角的合理范围。对比分析了两种典型控制算法的稳态特性和瞬态特性,稳态特性不依控制算法的改变而改变,控制算法二则明显提高了4WS 车辆的瞬态响应品质。研究结果为4WS 系统的开发提供了理论依据。
Based on the 2DOF linear bicycle model,the handling and stability of 4WS vehicle was studied herein.The rear wheel control algorithm was discussed in time domain and frequency domain in order to improve the maneuverability at low speed and stability at high speed.By using the lateral acceleration as 0.4g to define the effective working area for 4WS,the range for rear steering angle was derived.The steady-state and transient-state of two typical control algor…查看全部>>
