摘要
以四轮转向原理样车为对象,运用多体动力学理论对四轮转向车辆的转向特性进行了计算机仿真研究和试验验证。对建立整车多体模型的方法进行了论述。通过对仿真数据与样车试验结果的对比分析,证明了四轮转向多体模型各类参数和控制方法的正确性和适用性。最后利用建立的整车多体模型,仿真分析了前后悬架刚度对操纵稳定性的影响。
In this paper, both computer simulation with multi-body dynamics theory and related experimental verification on the steering characteristics of a four-wheel-steering (4WS) vehicle prototype are conducted. The comparison be tw een the results of simulation and experiment demonstrates the correctness of the parameters and control methods of the multi-body dynamics model for 4WS. Final l y, with two real examples, the effect of front and rear suspension stiffness on steering stability and the steering response characteristics during brake steeri ng are simulated based on multi-body dynamics model for complete vehicle.
