翻边对开孔方板拉伸强度的影响

Influence of Flanged-Cutout on the Tensile Strength of a Square Plate

本文利用ANSYS软件建立了翻边开孔方板的参数化模型,分析了单向拉伸载荷作用下不同开孔参数(开孔大小、翻边长度、翻边角度等)对开孔处应力强度的影响。研究发现,翻边的存在能有效提高孔边的强度,该结果为实际结构的翻边开孔设计提供了参考。

This paper used ANSYS software to establish a parametric model of the flanged opening square plate,and analyzed the influence of different opening parameters(opening size,flanging length,flanging angle,etc.)on the stress intensity at the opening under the unidirectional tensile load.The research found that the existence of the flange can effectively improve the strength of the hole edge,and the result provides a reference for the design of the flange opening of the actual structure.
