Title Barrel heating simulation device design
Abstract
The main role of the infantry automatic weapons for killing their remaining targets,it must ensure that adequate firing automatic weapons with a powerful , high rate of fire and a good shooting accuracy . However, a large number of automatic weapons firing process, the inner wall of the barrel subjected to high temperatures , resulting in the ablation effect after the gunpowder gases and high-speed flow of high pressure , abrasion and thermal stress , erosion and abrasion caused by the barrel gradually changing the barrel size. With the increasing number of projectiles, ablation and wear is gradually increased, gradually bore damage, projectile fired out of the ballistic performance also will be destroyed. Effects of erosion and abrasion and thermal stress on the weapon barrel life and shooting accuracy is a widely studied but has not yet been well resolved. So a barrel heating simulation device designed to study this erosion ,abrasion and thermal stress bore barrel when firing automatic weapons produced . Barrel heating simulation device including hardware and software design in two parts , the hardware part of the design of a heating device , using cylindrical resistance furnace to heat the barrel; software part of the virtual instrument development platform designed resistance furnace temperature control system in order to achieve real-time measurement and control the temperature of the furnace.
