A Simplified Friction Model for Tripod Constant Velocity Joint

As the tripod constant velocity (TCV) joint offer the lower plunge resistance compared to the ball joint, it has good behavior in noise and vibration performance. But the plunge friction inside the TCV joint will generate an unexpected axial force, which usually causes the vibration and noise. In this present work, a phenomenological TCV joint friction model was used in the numerical models of TCV joint based on ADAMS. This friction model incorporates the change of friction coefficient during the plunge-in and plunge-out motion and describes the rolling and slip friction situation in the TCV joint. So the friction at every parts of the TCV joint can be totally defined. The calculation results from traditional model and the simplified model were compared. The efficiency and accuracy of the simplified model was proved. Since then, the simplified TCV joint model can be used to predict generated axial force of TCV joint and vibration analysis. It will also make effect on the complex system analysis which contains the TCV joint
