扇环形半圆截面圆筒应力分布规律研究

采用ANSYS/workbench有限元软件,对扇环形挡板、半圆端板、半圆筒厚度均为20mm的扇环形半圆截面容器进行应力分析。分析结果表明扇环形挡板上的等效应力最大值出现在挡板的中心部位,半圆挡板、半圆筒的等效应力最大值出现在内表面的连接处。分析得到了扇环形挡板、半圆端板、半圆筒上等效应力的分布情况,同时,得到了扇环形挡板和半圆筒的内、外表面上高应力区与应力平稳区等效应力与区域的大小。研究结果为扇环形半圆截面容器的设计提供了参考依据。

Study of stress distribution principle of annular sector semicircular cross section vessel

By using finite element software ANSYS,the stress of the annular sector semicircular cross section vessel,which is made up of an annular sector plate,two semicircular plates and a semi cylindrical with the thicknesses of 20 mm,is analyzed.The analysis results show that the maximum equivalent stress of the annular sector plate appears in the middle of the plate,and the maximum equivalent stresses of the semicircular plate and the semi cylindrical appear in the inner surface connection place.The equivalent stress distribution trends of the annular sector plate,semicircular plates and the semi cylindrical are obtained.Meanwhile,the equivalent stresses and the sizes of the high stress areas and stress-stable areas in the annular sector plate and semi-cylindrical inner and outer surface areas are obtained.The research result provides a reference for the design of annular sector semicircular cross section vessel.
