【摘要】：針對(duì)連續(xù)管作業(yè)機(jī)在現(xiàn)場(chǎng)作業(yè)過(guò)程中頻繁發(fā)生連續(xù)管溜管、咬傷等問(wèn)題,提出摩擦系數(shù)區(qū)間對(duì)連續(xù)管安全夾持的影響研究。利用實(shí)驗(yàn)研究和數(shù)值計(jì)算相結(jié)合的方法,在不同軸向力和夾緊力工況下,研究摩擦系數(shù)對(duì)連續(xù)管等效應(yīng)力、等效塑性變形及連續(xù)管位移量的影響。以連續(xù)管屈服強(qiáng)度和2‰塑性變形為評(píng)判依據(jù),得出連續(xù)管安全夾持摩擦系數(shù)允許區(qū)間為0.4~0.6。該研究為連續(xù)管安全作業(yè)具有一定的指導(dǎo)意義,并為夾持系統(tǒng)設(shè)計(jì)提供科學(xué)依據(jù)。
[Abstract]:In order to solve the problems of continuous pipe slide and bite, the influence of friction coefficient interval on the safe clamping of continuous pipe is studied.In this paper, the effects of friction coefficient on the equivalent effect force, equivalent plastic deformation and displacement of continuous tube are studied under different axial force and clamping force by means of experimental study and numerical calculation.Based on the yield strength and 2 鈥，
