用于核电厂抗撞击设计的某型号大型宽体商用飞机有限元模型及其荷载特性研究

A Finite Element Model of a Large Commercial Wide-body Aircraft For Nuclear Power Plant Anti-impact Designing and Load Characteristics

在CAP1400核电厂抗飞机撞击分析研究中，根据上海核工程研究设计院开展的前期工作、特别是荷栽调研的结果，决定采用撞击速度为156m／s的某型号大型宽体商用飞机作为输入荷载。并采用LS—DYNA显式有限元分析软件进行模拟。本文研究了飞机模型的建立方法并分析了模型的荷载特性。

Based on the pre-works, especially the aircraft impact load research for CAP1400, a large by LS- aircraft with the velocity of 156m/s is chosen as the impact load and will be modeled by LS-DYNA. This paper studied the way to build the FE model and analyzed the impact load char-acteristics of the model.
