ajst-11369	Li, Jinfeng; Zhang, Jianbing; Meng, Qingtao	The Effect of Clamping Force and Friction Coefficient on The Clamping Clamp	2023	6	.pdf	application/pdf	4050	155	60	It is found that the stress of drill pipe joint is mainly concentrated in the contact position of drill pipe and the stress value of drill pipe joint shows a trend of increasing. However, too large friction coefficient will easily lead to the surface damage of drill pipe joint, and in serious cases, it will cause the skin of drill pipe joint to peel off and accelerate the corrosion of drill pipe, therefore, it is especially important to study the influence of friction coefficient on the process of punching buckle clamp.	cache/ajst-11369.pdf	txt/ajst-11369.txt
