摘　　要：为了解三叉杆-球笼式万向联轴器组合传动轴系统的动态特性,为以后的设计工作提供理论依据,对三叉杆-球笼式万向联轴器组合传动轴系统的滑移销、叉杆臂和钢球等关键部件进行了研究。运用ADAMS软件对三叉杆-球笼式万向联轴器组合传动轴系统建立了动力学仿真模型,并对其分别进行了无摩擦和有摩擦条件下的动力学仿真,得到了关键部件的受力曲线图和摩擦力曲线图。研究结果表明,在三叉杆-球笼式万向联轴器组合传动轴系统中,钢球受力曲线的波动和突变最大,说明钢球属于易磨损部件;相比无摩擦时的受力曲线,有摩擦时作用在各个部件上的受力曲线波动变强,更能反映出该三叉杆-球笼式万向联轴器组合传动轴系统的真实受力情况。In order to understand the dynamic characteristics of the tripod-ball type universal coupling composite transmission shaft system and offer the theoretical basis for the further design work,the key components,such as the sliding pin,the tripod arm and the steel ball,of the tripod-ball type universal coupling composite transmission shaft system were studied. Based on ADAMS,the dynamics simulation model of the tripod-ball type universal coupling composite transmission shaft system was built,and its dynamics simulation under the condition of friction and non-frictional were carried out. Then,this part obtained the corresponding force curves and friction curves of the key components. The results indicate that in the tripod-ball type universal coupling composite transmission shaft system,the force curve of the steel ball has the largest fluctuations and mutation,it is shows that the steel ball belongs to the most easily worn parts. Compared with the force curve of no friction,the fluctuations of force curve with friction that effected on each component becomes stronger,to better reflect the real force condition of the tripod-ball type universal coupling composite transmission shaft system.
