| 摘要步兵自动武器的作用主要用于杀伤有生目标，所以必须保证自动武器具有足够射击威力，高射速和良好的射击精度。但是自动武器大量射击过程中,枪管内壁受到高温、高压及高速流动的火药气体作用后产生烧蚀、磨损和热应力,枪管烧蚀和磨损引起枪管尺寸的逐渐改变。随着射弹数量的增加,烧蚀与磨损也在逐渐加剧，内膛逐渐受到破坏,发射出去的弹丸的弹道性能也随之破坏。烧蚀与磨损及热应力对武器身管寿命及射击精度的影响是一个被广泛研究但却仍未得到很好解决的问题。所以本次设计一个枪管加热模拟装置来研究自动武器射击时枪管内膛产生的烧蚀、磨损和热应力。枪管加热模拟装置包括硬件设计和软件设计两部分，硬件部分设计一个加热装置，采用圆筒式电阻加热炉来对枪管进行加热；软件部分采用虚拟仪器开发平台，设计了电阻加热炉温度控制系统从而实现加热炉内温度的实时测量与控制。20757 关键词 枪管 加热装置 热应力 烧蚀 寿命 毕业设计说明书（论文）外文摘要 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.
