摘　　要：以大飞机撞击为应用研究背景,开展飞射物撞击预应力钢筋混凝土靶板试验研究。采用1∶6的几何缩比率,设计与飞射物等效的缩比样品和预应力钢筋混凝土靶板,采用有限元分析软件构建碰撞模型,计算不同速度下2种结构缩比样品对靶板的撞击毁伤效果。采用气炮进行实物加载试验,通过与仿真计算结果进行分析对比,获得2种结构缩比样品对200 mm厚预应力钢筋混凝土的临界侵彻速度。所得结果可为直观预判/评估核电厂预应力钢筋混凝土安全壳冲击响应和破坏模式提供基础数据,也可为原型碰撞试验方案提供设计参考和依据。Based on the application research background of large aircraft impact,the experimental research is conducted on the impact of flying object on a prestressed reinforced concrete target plate.The scaled samples equivalent to flying object and prestressed reinforced concrete target plates are designed using a geometric scaling ratio of 1:6.Finite element analysis software is used to construct the collision models and calculate the impact damage effects of two scaled samples with different structures on the target plate at different speeds.A physical loading test is conducted using an air cannon,and the critical penetration velocity of two scaled samples on 200mm thick prestressed reinforced concrete is obtained by comparing the test results with simulated results.This provides basic data for intuitive prediction/evaluation of the impact response and failure mode of prestressed reinforced concrete containment in nuclear power plants,and also provides design references and basis for prototype collision test schemes.
