压力容器特别是大型球罐,在组装焊接过程中极易产生错边及角变形缺陷,该缺陷的存在将在容器中产生严重的应力集中。通过对现有文献有关错边及角变形的附加弯曲应力公式进行整理,并对其各式的实验数据进行考核分析,得出利用这些公式计算,很难从中找出一种理想的表达式,必须从其他途径来寻找方法。 Pressure vessels, especially large spherical tanks, are prone to produce mis-edged and angular deformation defects during assembly and welding. The presence of these defects creates severe stress concentrations in the vessel. Through the collation of the additional bending stress formula of the existing literature on the wrong edge and the angular deformation, and examining and analyzing various experimental data, it is difficult to find out an ideal expression by using these formulas. There are other ways we must look for ways.
