Thermal model for wet multi disc-clutches

This thesis aims to define a model for studying and ultimately predicting heat propagation in a mechanical component such as a clutch. The heat generated by the slippage motion of the discs primarily propagates through conduction within the clutch itself and by (forced) convection with the oil used for cooling. The model, developed using Amesim software, is designed with flexibility as its main goal, enabling it to be applied to any system design, once dimensional characteristics of the discs, the thermal properties of the cooling fluid, and the input data of power and torque are known. The model is calibrated using test bench results and applied to a transmission under development. The goodness of the method is supported by a mathematical model.
