摘要
采用飞射物-目标相互作用分析方法模拟分析大型商用飞机撞击核安全壳破坏效应,通过现场三维激光扫描技术与《飞机结构维修手册》的信息采用,正、逆向建模相结合的手法,创建了飞机精确模型,得到详细的飞机质量和刚度数据。并对空客A340-300型号商用飞机机型撞击安全壳时可能出现的多个变量分别进行了非线性动力学的数值模拟。分析飞机不同撞击速度、不同撞击高度、不同撞击角度及混凝土不同弹性模量等11个参数下,安全壳在不同工况时的破坏情况。
The response and damage of nuclear containment under large commercial aircraft impact were simulated by the projectile target interaction method. Through the results from three-dimensional laser scanning field measurement and Aircraft Structure Maintenance Manual,the precision aircraft model was modeled with positive and reverse mixed modeling method,and the aircraft quality and stiffness were obtained. In order to investigate the failure pattern of nuclear containment under different conditions,the numerical simulation of nonlinear dynamics was carried out considering 11 variables,including different initial velocities,impact heights,impact angles and concrete elastic modulus when airbus A340- 300 aircraft hit the nuclear containment.
