【摘要】 为利用终态侵深公式得到弹冲击混凝土目标过程中的瞬态量,根据实验现象及测试结果,借鉴Young氏方法的思路,提出一种“线性加速度模型”计算方法.利用该方法对侵彻弹冲击多层混凝土薄靶板及半无限厚混凝土目标分别进行了计算,并与前人的计算方法进行了对比.结果表明,该方法计算所得结果与实验结果一致,可为防护工程或武器设计提供理论和方法的参考.更多还原

【Abstract】 In terms of phenomena of the experiments and measurements from the tests,based on the penetration equations,referred to Young’s thought,a calculation method of "linear deceleration model" for a projectile impacting concrete targets is presented.The deceleration curves of a projectile impacting concrete targets are thus calculated.To verify the results of former method and the present method deceleration tests were conducted for the perforation of a projectile against multi-plates concrete targets and penetration of a projectile against half-infinite concrete targets by use of an on-board recording system.Predictions of present method showed good agreement with measurements from the tests.更多还原
