摘　　要：分别对单、双十字轴式万向节进行了运动分析,确定了转向系统输出轴产生转矩波动的影响因素。针对某车型转向系统的双万向节传动,利用RecurDyn软件建立了双十字轴式万向节的参数化模型,将各个可以变动的变量和坐标参数化并设定为设计变量,结合空间双万向节传动的等速条件,以输出轴的转矩波动达到最小为目标进行优化设计。最终获得了最佳的转向系统硬点布置方案,使转向系统输出轴的转矩平稳无波动。Kinematic analysis respectively to the unitary and the double cross universal joints are carried out.The influence factors of the torque fluctuation on the steering system output shaft are determined.Using the RecurDyn software,double cross universal joints parameterization model are established.Defining variables and coordinates as parameter-based design variables,the optimization design aimed at the minimum torque fluctuation to the driveshaft can be made with the constant-velocity condition for spatial double cross universal joints.An optimum hardpoint layout is obtained,a smooth torque on steering drive output shaft without any undulation is achieved.
