| Summary: | According to the engagement characteristics of wet clutch， average Reynolds equation and elastic contact model of two rough surfaces are applied to establish a dynamic transfer torque model for wet clutch engagement. Dynamics model of joint start for wet dual clutch is established based on the dynamic transfer torque model of wet clutch engagement in vehicle start， and the model is simulated and validated in Matlab/Simulink platform. Taking the startup with 20% throttle opening as example， two joint start process of wet dual clutch are analyzed and compared respectively on the basis of the dynamic and static transfer torque model. Results show that the simulation based on dynamic transfer torque model can more actually characterize the changes of rotation rate， jerk and friction work in the start process of wet DCT. |
