I-spiral seam efakwe emanzini i-arc welded steel pipe igrunjwa ngokujikeleza kwaye iqala ukungena kukwakheka okuthambileyo.Ngaphantsi kwesenzo se-tri-cone, i-drill kuqala ivelisa i-elastic shear deformation ye-stratum kwaye isuswe phantsi koxinzelelo lwe-tri-cone.Kwimeko edibeneyo, umhlaba othambileyo ubumba i-homogeneous, kungakhathaliseki ukuba i-stratum kunye nokuqhekeka komhlaba.I-Horizontal directional drilling iqhutyelwa ngokuqulunqwa ngokukhawuleza, kwaye ukubunjwa ku-random kunye noqhagamshelwano oluguquguqukayo kunye ne-roller cone bit.Ukukhuhlana kwenzeka xa ikhowuni idibana nomhlaba.Amandla empembelelo abangela ukuba umthungo ojikelezayo ontywiliselwe i-arc wentsimbi umbhobho wentsimbi ungcangcazele.Xa isuntswana le-tri-cone lisuka kulwakhiwo oluthambileyo ukuya kulwakhiwo oluqinileyo, ngokuqinisekileyo luya kuvelisa ukungcangcazela okukhulu kwecala kunye nokunyuka nokuhla kwentshukumo.

Xa isantya sokomba siyi-0.008m/s kunye nesantya sokujikeleza kancinci si-2 radians/s, ijika le-pseudo-strain energy ngexesha lenkqubo yokuqhubela phambili ye-roller cone bit ikakhulu ibandakanya i-viscosity kunye ne-elasticity.Nangona kunjalo, kuba igama le-viscous lihlala lilawula, ukuguqulwa kwamandla amaninzi kumandla oxinzelelo lwepseudo alunakuguqulwa.I-deformation energy ye-spiral seam submerged arc welded steel pipe ngawona mandla asetyenzisiweyo ukulawula ukuguqulwa kwehourglass.Ukuba i-pseudo strain energy iphezulu kakhulu, oko kuthetha ukuba amandla okulawula ukuguqulwa kwe-hourglass inkulu kakhulu, kwaye i-mesh kufuneka icocwe okanye iguqulwe.Ukunciphisa uxinzelelo olugqithisileyo lwe-pseudo amandla.Utshintsho olukhawulezileyo lwe-pseudo strain energy kulo mzekelo luyenzeka ikakhulu xa i-drill bit ingena kumaleko omhlaba othambileyo kwaye i-cone bit idlula kwi-interface yokwakheka kotshintsho ngequbuliso.Okukhona ukuqina kokwakheka, kokukhona ukuqina koxinzelelo lwe-pseudo kwi-drill bit ekubunjweni.Linganisa inkqubo yokomba yombhobho we-spiral welded ekubunjweni ngokukhawuleza kwaye uqikelele utshintsho lwe-drill bit's drilling trajectory.
