A Simplified Close Form Approach, For Slipping Clutch Thermal Model 2001-01-1148

The objective of this work is to generate a robust slipping-clutch model that will be employed as a component for driveline dynamic simulations. The model was mainly focused on the relatively detailed slipping-clutch interface temperature evaluation. The core reason for including interface temperature computation is to better estimate the dynamic coefficient of friction. The contribution of this work is in the development of a simplified close-form approach to solve the thermal field problem at the clutch interface. Compared with implicit numerical methods (such as the finite difference method), the close-form approach reduces the computational cost significantly. In addition, this model can be embedded in commercially available simulation software (such as MATLAB¹ and EASY5²) without the need to consider the numerical integration methods, which generally are a concern when implicit numerical methods are used.
