Modelling of E-clutch axial dynamics based on experimentally characterized clutch component stress-strain characteristics

Lumped-parameter E-clutch axial dynamics model was proposed and parameterized based on experimental identification of input-output characteristics.Here, stress-strain characteristics of individual components of disassembled clutch are characterized by using a manually powered spindle-based test rig. The obtained characteristics are firstly used to parameterize the initial, simplified model. While the experimental validation results show satisfactory prediction of the clutch torque static curve, prediction of normal force static curve is worse, thus indicating a potential for further model improvements. Therefore, new, more detailed versions of model containing individual component stress-strain characteristics are gradually proposed and experimentally validated. The validation results indicate considerable improvements in normal force static curve prediction accuracy.
