Abstract:The friction-loaded load simulator is different from general load simulator, and the simulator load friction to eliminate the surplus torque and widen the bandwidth. The simulator's mathematical model of temperature field on friction slice was established based on thermodynamic theory and tribology theory. By a pair of friction's relative movement as a research object, the friction disk surface temperature field's distribution law under different pressure and different speed was analyzed by using ABAQUS software. The results show that the temperature of the contact interface of friction disk is proportional to the pressure. The friction disc temperature of interface is proportional to the rotating speed between the friction disk and slice. When cooling by ventilation, the temperature declines a lot, and the rising rate of temperature is also significantly reduced.
