When a clutch disk of 4-wheel drive vehicle get severe friction forces from transmission, slip phenomenon where friction plate is worn out will happen. This phenomenon let the clutch have a lower efficiency, and has a harmful effect for vehicle users. However, the problem we need to note is an increase of temperature related to decreasing friction coefficient which let output torque of the clutch decreased. So, it needs to be modeled for estimating increase of the clutch as 3steps. There are dynamic model, thermodynamic model, friction coefficient model. In this paper, only dynamic model is dealt with in detail. This model contains loads, mechanical factors such as any shaft, ramp, rollers, a solenoid, primary and secondary clutch to calculate how much heat generated. It is based on Matlab & Simulink program to simulate the operation of whole parts of the clutch.
