The Constant Velocity Joint(CVJ) is an important automotive part in the driveline system. There are various types of CVJs. CVJ consists of several parts and these work to 3-dimensions as they rotate and transmit torque to the tire and wheel. In these processes, CVJ"s parts generate friction force, dynamic force and vibration. These characteristic are very important about CVJ performance. So, many engineers have studied for a long time in variety of ways. In this paper, we developed an ADAMS-based CAE tool for automated model generation and standardized dynamic simulation of almost all kind of type CVJ for automotive driveline applications. We specifically study the tripod types of CVJ for plunging force. Plunging force is generally generated mainly when the vehicle is in idle stop. Plunging force is not correlated between test and simulation using coulomb friction model. So, we introduced the LuGre friction model and applied the tripod type CVJ of simulation model.
