摘要:

为提高核电厂抵抗飞机蓄意撞击的能力,应用经典显式非线性有限元动力程序LS-DYNA,并采用HAD101/04标准中提供的撞击荷载函数模拟分析飞机撞击反应堆安全壳外壳。混凝土和钢筋分别采用Johnson_Holmquist_Concrete、Plastic_Kinematic本构模型,模拟这2种材料在飞机撞击时产生的大应变、高应变率的非线性性能。计算结果表明,某反应堆安全壳完全有抵抗HAD101/04中波音707-320型飞机撞击的能力。

Abstract:

 

In order to assess and enhance the capability of nuclear power plants to stand the deliberate crash of aircraft, the classical explicit nonlinear finite element dynamic program (LS-DYNA) was adopted, in which the impact load function in HAD101/04 was used on the containment of a nuclear reactor. The constitutive model of Johnson_Holmquist_Concrete and Plastic_Kinematic were used respectively to simulate the nonlinear performances of concrete and steel when aircraft crashing: large strain and high strain rate. The results show that the reactor containment can resist the impact of Boeing 707-320 simulated by HAD101/04.
