摘　　要：分析了单万向节传动时,万向节位置对输出轴转速曲线相位的影响;在此基础上研究了双万向节传动时,两个万向节波动叠加的原理,并拓展到多万向节传动。针对带有减速齿轮的传动结构,分析了锥齿轮处转速的传递,以及多个万向节的波动叠加,确定了本次优化的基础。最后针对某一具体车型的转向机构进行了优化,找出各万向节相位角的最优值,将输出轴的转速波动降低到最小。The effect of universal joint position on the output shaft speed curve phase is analyzed in single universal joint transmission. Then, the fluctuation superposition principle of double universal joint transmission is studied and expanded to multi universal joint transmission. For transmission structure with reduction gears, the delivery of speed at bevel gears and fluctuation superposition of multiple universal joint are analyzed. Finally, by finding the optimum value of the phase angle of each universal joint, the speed fluctuation of the output shaft of a specific vehicle steering mechanism is reduced to a minimum.
