为了研究水下远场非接触爆炸中,局部细小结构(开孔和肘板)的简化对舱段冲击响应的影响。选用某油船舱段作为模型,根据不同简化形式建立4个不同的有限元模型,进行对比分析。结果表明:在冲击响应的计算过程中,省略局部细小结构可以保证足够的精度。
為瞭研究水下遠場非接觸爆炸中,跼部細小結構(開孔和肘闆)的簡化對艙段遲擊響應的影響。選用某油船艙段作為模型,根據不同簡化形式建立4箇不同的有限元模型,進行對比分析。結果錶明:在遲擊響應的計算過程中,省略跼部細小結構可以保證足夠的精度。

This paper mainly researches the influence of the local simplification of the small structures (cutout and bracket) on shock response of cabin. An oil tanker cabin is selected to build four different finite element models for the comparison and analysis according to the different simplification mode. The results show that it could remain enough precision when the small structures were omitted during the computation of shock response.
