卵形头部弹丸侵彻混凝土的研究
Study on Penetration of Concrete Targets by Ogive-Nose Steel Projectile
摘要
Abstract
We conducted acceleration-time measurement of penetration experiments in targets with 100 mm diameter,4.0 caliber-radius-head,25 kg projectiles.The 3 m×3 m×3m and 2 m×2 m×2m concrete targets had an nominal Projectiles were designed to contain a single-channel acceleration data recorder,so we recorded accelerations in the bore of the gun and accelerations during the penetration event.A 100 mm diameter powder gun launched the 25 kg projectiles to striking velocities between 310 and 632 m/s.We compared the measured penetration depths and acceleration-time data with the calculated results using Forrestal formula.The calculated results are in good agreement with rigid-body acceleration measurements for the rise times and peak plateau responses.The acceleration-time data of projectiles can be helpful for devising armour-piercing projectile and defense engineering.关键词
