摘　　要：以某双转向桥汽车为研究对象,建立二自由度模型,评价双转向桥汽车的稳态响应。运用Matlab软件对单转向桥汽车和双转向桥汽车在前轮角阶跃输入下的稳态响应进行仿真分析。结果表明,在一定车速下增大前轮转角,双转向桥汽车具有更小的转向半径和更小的质心侧偏角,能更好地保持车身稳定转向的能力。Taking a double-steering axle vehicle as the research object,a two-degree-of-freedom model was established to evaluate the steady-state response of a double-steering axle vehicle.Matlab software was used to simulate and analyze the steady-state response of single-steering axle vehicles and double-steering axle vehicles under the input of front wheel angular steps.The results show that the double steering axle car has a smaller steering radius and a smaller centroid side deflection angle at a certain speed,which can better maintain the stable steering ability of the body.
