问题的提出:在设计车辆转向梯形时,由总布置决定的机构基本参数确定后,可以采用解析法计算出每一组给定的梯形机构参数R(梯形臂长度)、γ(梯形臂夹角)所对应的ρ_m(平均相对转角误差,ρ_m愈小则转向性能愈好),或用作图法进行校核。但 Proposal of the problem: After designing the steering trapezoid of the vehicle, after determining the basic parameters of the mechanism determined by the general arrangement, an analytical method can be used to calculate the parameters of each set of trapezoidal mechanisms R (trapezoidal arm length) and γ (trapezoidal arm included angles). The corresponding ρ_m (average relative rotation angle error, the smaller the ρ_m is, the better the steering performance is), or it can be used as a graph method for checking. but
