Abstract: 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.
