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 effect of collision of large commercial aircraft on nuclear containment was simulated and analyzed by using the method of fly-object-target interaction analysis. Through the combination of on-site 3D laser scanning technology and the information of Aircraft Structure Maintenance Manual, positive and negative modeling, Accurate model of the aircraft, get the detailed aircraft quality and stiffness data. The nonlinear dynamics numerical simulations of several variables which may occur when the Airbus A340-300 commercial aircraft collided with the containment were carried out respectively. The destruction of containment under different working conditions under different 11 different parameters such as different impact velocity, different impact altitude, different impact angle and different elastic modulus of aircraft was analyzed.
