摘　　要：在同等容积的储存容器中球罐具有受力最好、用材最省的优点,近几年,越来越受到用户的重视,所以球罐的经济性设计成为设计工作者的主要任务。特别是大型球罐,减少球罐的焊缝长度,既减少焊接安装工作量,缩短了安装工期,又减少了投资,其经济性更明显。球罐设计过程中,强度校核在GB 12337—2014《钢制球形储罐》中有明确的规定,可以采用过程设备强度计算软件SW6来完成。分片计算目前没有现成的计算软件,该文结合GB/T17261—2011《钢制球形储罐型式与基本参数》标准,推导出D i=7100 mm球壳板分片计算方法,并通过了实例验证。Spherical tanks in the same volume of storage containers have the best strength and the least materials.In recent years,spherical tanks have received more and more attention from users,so the economic design of spherical tanks has become the main design task.Especially for large spherical tanks,reducing the length of the welding seam of the spherical tank not only reduces the welding and installation workload,shortens the installation period,but also reduces the investment,and its economy is more obvious.In the process of spherical tank design,the strength check is clearly stipulated in GB 12337—2014“Steel spherical tanks”,which can be completed by the process equipment strength calculation software SW6.There is currently no ready-made calculation software for fragmentation calculation.This article combines the GB/T17261—2011“Steel spherical tankstype and dimension data base”to derive the fragmentation calculation method of D i=7100 mm spherical shell plate,and passes the example verification.
