摘　　要：考虑了爆轰波和结构塑性变形的相似律问题,研究在大尺度缩比船体模型在穿舱爆炸条件实验中,使用畸变相似律处理模型得到对原模型局部毁伤效果等效评估的方法。通过对4种船体结构缩比实验方案进行穿舱爆炸数值模拟分析,并对实际模型毁伤效果评估误差进行总结,得到当缩尺比为λ=0.25、畸变比为φ=2.5时,实验模型能在工程允许的误差范围内可实现对原模型局部毁伤效果的准确评估,得到满足生产可控性和经济性的最终实验方案。结论可为大尺度缩比船体模型穿舱爆炸实验的应用提供参考。The similarity law of the detonation wave and the plastic deformation of the structure are considered and equivalent assess method for the local damage of the real ship through distortion model in penetration explosion experiments of the large scale model is studied.Through penetration explosion simulation analysis on four kinds of scale experimental scheme and the summary of error of real damage results,it can be concluded that when scaled ratio λ is 0.25 and distortion coefficient φ is 2.5,the local damage of original model can be assessed accurately by the model experiments within appropriate engineering application which meets the manufacturing production and the economic demand.The conclusion can provide application references to the penetration explosion experiments of the large scale model.
