MATHEMATICAL MODELING OF HEAT FRICTION CONTACT MASTER BELT WITH THE GUN MOUNT BARREL DURING THE PROCESS OF HIGH-SPEED MOTION

The friction in the gun mount barrel at sliding speeds of artillery projectile 500 - 700 m/s is not sufficiently studied. The main problem is to increase the efficiency of the master belt with a significant increase of the interaction parameters of the barrel with the projectile. To determine the effect of heating on the change of physical and mechanical properties of the surface layer and friction coefficient on the surface of the master belt were made mathematical modeling of heat transfer.
