摘要
A finite element model of the pressure plate and friction plate of the dry dual clutch is established to find the temperature rise of a dry double clutch in operation.Different starting conditions for the temperature of the dry dual clutch are obtained by calculating the temperature rise,and a comparative analysis of the results is conducted.Results show that the temperature rise for clutch 2 is generally higher than that for clutch 1,and the temperature rise of clutch 2 is higher than that of clutch 1,with an increasing throttle opening.A curve of the speed difference between engine and friction plates is extracted by calculating the source power of the wear of the sliding mill.It is found that the clutch speed difference of clutch 2 is generally higher than that of clutch 1 because clutch 1 follows a constant-rotation-speed control strategy at the start of grinding,leading to the temperature rise of clutch 2 being greater than that of clutch 1.A constant-engine-speed shift strategy is finally put forward.
