Simulation of colloidal slip with double friction force in automatic directional drilling
摘要
Abstract
The automation degree of sealing technology in coal mine is insufficient,and the automatic directional drilling rig can im-prove the automation degree of sealing.A colloidal slip with double friction force for automatic directional drilling machine is de-signed to solve the problem that the clamping device of automatic directional drilling machine is bad.Two kinds of colloidal struc-tures are proposed to realize the difference of friction between active drill pipe jointing and unjointing,and to ensure the smooth jointing of drill pipe.Using the nonlinear finite element method,Mooney-Rivlin strain energy function was used to describe the mechanical properties of colloid,and the simulation of colloid clamping hole sealer was carried out.The working friction of colloid of different materials was obtained,and the rationality of the two structural colloids was verified.The influence of the compression amount of adhesive strip on the surface of the colloid on the stress of the hole sealer was studied.The effect of the number of adhes-ive strips on the colloidal surface on the axial friction force was investigated.The results show that natural rubber and polyurethane rubber are reasonable as colloidal materials,the compression of rubber strips is 0.9 mm,and the number of rubber strips is 3.关键词
