The results showed that the higher thedischarge voltage or charge capacitor was, the higher the temperature of the plasma was,and the longer plasma discharge time was. There was a late discharge when the inputenergy reached the critical value. The greater the capacitance or voltage was, the earlier thelate discharge of the plasma was. The temperature changes of plasma at the beginning of alate discharge were not significant under different discharge conditions. Each SCB had itstemperature range respectively.

The frictional heat energy was concentrated on the thermal effect layer with the thickness of 4 mm, The temperature gradient of contact surface is the highest, and decreased rapidly with the radius direction of the lining's groove. The temperature gradient and TEL's thickness increased with the increasing of the sliding speed. The temperature decreased rapidly with the radius direction and also with the increasing of center angle of the lining's groove. The sliding speed and distance are obtained under two sliding conditions when the lining fails, which supply the theoretical basis with the antislip design of friction hoist.
