A dynamic model of an automotive dry dual clutch is proposed and experimentally validated for a wide range of operating conditions, including those related to thermal expansion and wear effects. The bond graph method is used to derive the model and analyze its simplification. The main model maps, which relate to stress-strain curves of key clutch assembly components, are identified by using a custom-made manual press rig. The clutch coefficient of friction is described as a function of temperature, slip speed, and normal force, which is determined from the CNC tribometer characterization data. A lumped-parameter third-order thermal dynamics model is proposed and experimentally identified, in order to accurately predict the pressure plate and flywheel friction interface temperatures. The overall clutch model, including an electromechanical actuator sub-model, is validated against experimental data collected on a custom-made clutch test rig.
