Dynamic Simulation of Twin Tripod Sliding Universal Joint

In this paper, taking the twin tripod sliding universal joint as three-dimensional solid model, adding various kinematic pairs and motion drivers between kinds of components, using multi-body dynamics software ADAMS that is popular at present, carrying out the dynamic simulation, contrast with or without friction force of the coupling’s movement under the action of those forces, such as the force on the slider, ball head, the journal, and so on. Finally, we obtained the movement rules of the couplings under or without those forces and some qualitative theories, which provided theoretical basis and reference for the subsequent design and research for couplings.
