本文对接管轴向推力作用下圆筒形容器开孔—补强区的应力应变场进行了详细的试验研究及三维有限元分析。研究结果表明,在补强圈补强的范围内。容器上的应力包括孔边应力集中明显降低。但由于几何形状、尺寸的变化及焊缝的加强作用,在补强圈外边缘,特别在容器横向截面(θ=90°)内,容器中将出现一高的不连续应力,从而使该区域成为整个接管的危险区域。
In this paper, a detailed experimental study and three-dimensional finite element analysis of the stress-strain field of a cylindrical container opening-reinforcement zone under axial thrust are taken. The results show that the scope of reinforcement in the reinforcement circle. Stress on the container, including the edge of the hole, significantly reduced the concentration of stress. However, a high discontinuity in the container will occur at the outer edge of the reinforcement ring, particularly at the transverse cross-section of the vessel (θ = 90 °), due to changes in geometry and size and weld strengthening, Become the entire danger zone to take over.
