摘要
APC壳(Air Plane Crash Shell)是核电厂抵御飞机撞击的主要屏障,本文运用非线性有限元程序LS-DYNA对某核电厂燃料厂房APC壳进行了分离式建模,并对大型商用飞机的撞击进行了数值计算,对APC壳的动力响应及弹塑性特性进行了研究分析,提出了大型商用飞机撞击局部效应的观点,为APC壳的设计计算提供参考。
APC shell is a important barrier of protection agaist Airplane Crash. This paper describes global nonlinear analysis on the 3D-solid APC model embedded with reinforced based on LS-DYNA program. The numerical implementation of large commercial airplane crash is conducted. Dynamic responses and elastoplastic character of APC shell structure are studied. Local effect crash is put forward. The calculation result can shell. view with large commercial provide reference for design airplane of APC shell.
