| Abstract: | Under the repeated action of high temperature and high pressure gunpowder gas and high speed projectile,the inner bore was worn at different degree.Measuring its radial wear is important to the firing performance and the remaining life of the gun barrel.The measurement methods and techniques of the inner diameter of various gun barrels were analyzed and compared.The development trend of non-contact caliper measurement technology and the prediction of the gun' s residual life which are closely related to the radial wear quantity were discussed. |
