Mu makuru yanyuma, uburyo bwo gushushanya uburyo bunini bwa strip ultrasonic plastike yo gusudira ifatanyirijwe hamwe byasabwe kandi bigenzurwa nubushakashatsi.Ubwa mbere, amahembe yo gusudira amacakubiri agabanijwemo ibice byinshi kuburyo igishushanyo cyamahembe yo gusudira cyerekanwe hamwe nuburyo bugoye gihindurwa muburyo bworoshye bwo gusudira.Noneho ikintu gihuriweho kigereranwa na kimwe cya kabiri cya oscillator hamwe nigice kimwe urebye guhuza kunyeganyega.Ingano yinshuro yingingo iboneka hakoreshejwe igitekerezo cyo guhuza imashini ihwanye.
Hanyuma, ingaruka zumubare wikibanza, ubugari bwikibanza nuburebure bwikibanza ku guhindagurika kuranga guhuza gusudira byakozwe hakoreshejwe ikigereranyo.Ukurikije ubu buryo, amatsinda menshi yubunini bunini bwa strip groove yarateguwe kandi arakorwa.Ibisubizo byubushakashatsi byerekana ko indangagaciro zapimwe na theoretique ya rezanse yinshuro yingingo zasuditswe zihuye neza.
Nkuko bigaragara ku gishushanyo gikurikira.Uburebure, ubugari n'ubugari bw'ihembe ryo gusudira ni L, B na T.Fata z axis nkicyerekezo cyo gushimisha transducer.Ku nshingano zakazi, urukiramende rwo gusudira rufatiro ruzatanga icyiciro cya mbere cyigihe kirekire cyo kunyeganyega mu cyerekezo cya Z.Kubice byo gusudira bifatanye, L≥2T, B na L birashobora kugereranywa, bityo guhindagurika guhindagurika kwingingo zo gusudira mu cyerekezo X birashobora kwirengagizwa.
Kuberako ihindagurika rya transvers mu cyerekezo rifite uruhare runini ku kunyeganyega birebire, mubisanzwe bigereranywa no gusunika.Ihembe ryo gusudira rigabanyijemo ibice (n + 1) mugukingura kimwe n uduce mu cyerekezo Y.Ubugari n'uburebure bwa buri kibanza ni W na L2, kandi ibibanza bitandukanijwe no kwinjiza no gusohora amahembe yo gusudira l1 na L3.Kugirango umenye neza ko buri gice kingana rwose, imiyoboro yubugari W / 2 igomba gufungurwa kumpande zombi zamahembe yo gusudira.Rero, buri cyuma cyo gusudira ni amahembe ya trapezoidal hamwe nigice cyurukiramende.Dufashe ko ubugari kumpera zombi no hagati ya buri gice ari D1 na D2, birashobora kugaragara uhereye hejuru: L = L1 + L2 + L3
Bitewe nuburyo bumwe hagati yibintu, ibisohoka amplitude yo gusudira nabyo bizanyeganyeza icyitegererezo, kandi iyo bihujwe, ihembe rya ultrasonic naryo rizagira ubu buryo, kuburyo igishushanyo mbonera cya ultrasonic kizoroha mugushushanya icyaricyo cyose element.Byongeye kandi, birasa.Kugirango uhagarike neza kunyeganyega kwa transvers no kwemeza ko ihembe ryo gusudira rifite ubukana butajegajega, ubugari bwamahembe yo gusudira bugabanijwe na groove muri rusange!/ 8 ~!/ 4./ 25 ~!/ 20 [7], umubare wimibare yo gusudira urashobora kugenwa ukurikije ibipimo byavuzwe haruguru.Kuberako ubugari bwamahembe yo gusudira muri rusange ntabwo arenga!PI / 4, birashobora rero gusesengurwa hafi yigitekerezo kimwe.Igice icyo ari cyo cyose cyo gusudira mu gice cya 1 gishobora gufatwa nkigizwe nimirongo itatu iringaniye.
Aluminium alloy 7075 (Modulus yumusore E = 7.17 * 1010N / M2 ubucucike ρ = 2820kg / m3, igipimo cya Poisson V = 0.34) cyatoranijwe kugirango gisudire ihembe.Ingano (1) ~ (3) na (6) yakoreshejwe mukubara umubare n, uburebure L2 n'ubugari W bwibice bitandukanye.Iyo uburebure bwa resonant L ya strip yo gusudira ihembe ihinduka hamwe nubugari B, uburebure bwa resonant L ya strip yo gusudira ihembe rihinduka hamwe nubugari B. Kubara resonant frequency yabazwe f = 20kHz, L1 = L3 kubworoshye.Iyo uburebure bwikibanza nubugari bihoraho, uburebure bwa resonant burahinduka hamwe nubugari bwamahembe ya weld mugihe umubare wikibanza utandukanye.L2 = 60mm, W = 10mm.Nkuko bigaragara kuri FIG.2, kuri ihembe ryerekanwe gusudira ryerekanwe muri FIG.1, uburebure bwa mbere bwa resonance uburebure ni buto kurenza ubw'ihembe ryo gusudira ridafite ibara ribarwa ukurikije inyigisho imwe (126mm), kandi uburebure bwa resonant y'ihembe ryo gusudira bwiyongera hamwe no kwiyongera k'ubugari bw'ihembe ryo gusudira, ariko kwiyongera bigabanuka buhoro buhoro.Mubyongeyeho, iyo rezanse yumurongo nubugari bwa weld bihoraho, uburebure bwa resonant ya weld buragabanuka hamwe no kwiyongera kwumubare.
Hiyongereyeho, ingingo eshatu zasuditswe zifite ubunini butandukanye zakozwe na aluminium alloy 7075 (ibikoresho bimwe nkuko byavuzwe haruguru).Umubyimba T w'izi ngingo eshatu zasuditswe hamwe na metero zapimwe zahujwe na vibration frequency FM yatanzwe.Iyo uburebure bwamahembe yo gusudira butarenze kimwe cya kane cyuburebure bwumuraba (hano ni 63mm), gutandukana kwinshuro zapimwe ninshuro zishushanyije ntiziri munsi ya 2%, zishobora kuzuza ibisabwa mubisabwa mubuhanga.
Inzira ndende ya ultrasonic ya pulasitike yo gusudira yagabanijwemo ibice byinshi bingana kandi ikigereranyo cyinshuro yikintu cyahurijwe hamwe hakoreshejwe uburyo bwo kwimura matrix.Niba ubugari nubunini nubunini bwikibanza bizwi, ikigereranyo gishobora gukoreshwa mugushushanya umurongo byoroshye, bityo bigatanga ishingiro ryuburyo bwo gushushanya umurongo.Uru rupapuro runasesengura ingaruka zumubare wikibanza, ubugari bwikibanza nuburebure bwikibanza ku bunini bwo gusudira hifashishijwe ingero.Birashobora kugaragara ko ubu buryo nabwo bugira uruhare runini muburyo bwiza bwo gusudira hamwe
Gucamo ibice nyuma yo gusesengura amahembe yinyeganyeza, ihembe ryo gusudira rishobora kugabanywa mumubiri wanyuma hamwe ningirabuzimafatizo yo hagati, ukoresheje uburyo bwuburyo bugaragara bwa elastique n'ingaruka z'umurongo woherejwe, uburebure bwibice bine bitandukanye butangwa hamwe na icyerekezo cyo murwego rwohejuru rwo kugereranya inshuro, kugereranya inshuro zirashobora gukoreshwa mugushushanya ihembe rirerire ryo gusudira ihembe, ariko inzira yo gushushanya iragoye, Guhitamo ibipimo bimwe biterwa nuburambe kandi ntabwo byoroshye mubikorwa byubwubatsi.Muri iyi mpapuro, umugozi wo gusudira uduce ugabanijwemo ibintu byinshi bingana no gushyira mu gaciro, kandi inshuro zingana zingana zo gusudira zifatika ziboneka hakoreshejwe uburyo bwa matrix uburyo bwo gutanga, butanga ishingiro ryuburyo bwo gushushanya umurongo wo gusudira.Igishushanyo gifite imibare yoroheje yo kubara hamwe nubusobanuro bugaragara bwumubiri, butanga uburyo bworoshye kandi bworoshye kubushakashatsi bwa strip
gusudira.
