铁钻工上卸扣的最大主动扭矩分析
An Analysis of the Maximum Torque Provided by Iron Roughnecks
摘要
Abstract
Aiming at the biting and peeling phenomenon of pipe string in the process of makeup or breakout with iron rough-necks,a research method is established to describe relationships between the maximum active torque and the clamping force from aspects such as biting,cutting and friction between tong dies and pipe string.Firstly,elastoplastic calculation and da-mage failure analysis were carried out for the process of tong dies biting into the pipe string,and biting depths were obtained.Secondly,friction experiments between tooth-shaped friction blocks and friction rings,which was made with materials of tong dies and pipe strings respectively,were conducted to determine friction coefficients.Cutting forces were simulated by a three-dimensional finite element model of a single tooth cutting pipe steel,and maximum active torques were determined.Finally,influences of tooth shape parameters on the maximum active torque provided by the iron roughneck during makeup and breakout were analyzed.A theoretical basis is provided for optimizing both tong die structure and operating parameters and improving performances of iron roughnecks.关键词
