基于实现转向条件 ,结合四杆机构的环路方程 ,建立起了车辆转向四杆机构近似运动综合的目标函数。根据极值条件 ,获得相应的方程组。基于消元法 ,推导出只含一个变量的多项式方程 ,以获得机构综合的所有解 ,从而可选择出最优解 Based on the realization of the steering conditions and the loop equation of the four-bar linkage, an objective function for the approximate motion synthesis of the four-bar linkage of the vehicle is established. According to the extreme conditions, get the corresponding equations. Based on the elimination method, a polynomial equation containing only one variable is derived to obtain all the solutions of the mechanism synthesis, so that the optimal solution can be selected
