| Popis: | 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 the thermal expansion effects and the wear effects. The bond graph method is used to derive the model and to analyze its simplification. The main model maps, which relate to the 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 the temperature, the slip speed, and the normal force, which is determined from the tribometer characterization data. A lumped-parameter third-order thermal dynamics model is proposed and experimentally identified, in order to predict accurately the pressure plate and the flywheel friction interface temperatures. The overall clutch model, including an electromechanical actuator submodel, is validated against experimental data collected on a custom-made clutch test rig. |
