摘要
Abstract
Based on the restitution coefficient of elastic collision, the projectile in-bore motion model was proposed with design parameters mainly considered. Analyze the influence of projectile’s main structural parameters on the motion. The approximate method that the restitution coefficient was seen as constant wasn’t used. Through the finite element simulation on the simplified model of gun-projectile system, the functional relation between the restitution coefficient and the radial velocity of the front bourrelet was acquired. The characteristic parameters of the 155mm shrapnel were used as the calculation parameters. Calculation and analysis about the various factors influence on the motion. The results show that there is general regularity between the projectile’s structural parameters and its in-bore motion characteristics. It is useful for selecting a reasonable structure for the projectile to ensuring the regular in-bore motion.关键词
