The developed vertical coil tong consists of many pole members,of which the right flexural pole is the weakest in strength.
右曲杆是立式吊具强度最薄弱的杆件,利用机构的受力分析方法确定了吊具右曲杆的受力大小及方向,在此基础上用有限元法对其进行了应力场分析,发现右曲杆受拉区内凹部分应力集中严重,是其薄弱环节;且现场应力测试结果表明有限元计算值与实际相符。
The mechanical principle and the manufacture of the steel barrel type barer,and its operation in the substation ground network construction have been introduced.
