Experimental Research on the Impact of Flying Object on Prestressed Reinforced Concrete Target Plates
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.
