Parametric analysis for a paper-based wet clutch with groove consideration

A three-dimensional thermohydrodynamic analysis of a wet clutch is performed that covers the entire cycle of engagement from slip to lock to detachment. The contact condition of the rough surface is formulated by the statistical micro-contact model to incorporate the elastic-plastic asperity contact, which is characterized by the plastic index. Based on the parametric analysis, it is shown that the performance of a wet clutch is influenced by various groove effects. The evolution profile and the distribution of temperature provide insight into the thermal behaviors and the potential application.
