【摘要】 介绍了四轮转向汽车四轮机构的基本运动关系,系统地分析了二自由度四轮转向汽车模型的运动方程,建立四轮转向汽车的物理和数学模型,得到质心侧偏角与前轮转角之间的传递函数。在此基础上对四轮转向汽车运用Matlab软件进行仿真分析,得出了四轮转向汽车与传统两轮转向汽车相比的优势。更多还原

【Abstract】 This paper puts forward the motion relationship of steering wheel of vehicle four wheel steering (4ws) system, and analysis the motion equation of 4ws model with tow freedom degree. Physical and mathematical model were established for vehicle with 4ws in this paper. And the transfer function of deflection angel of mass center to steering angel of four wheels was got. Then simulative analysis was taken on this basis .At last, the advantages of vehicle with 4ws was concluded compared with 2ws.更多还原
