Ukuhlolwa Kwezakhiwo Ezisekelayo Zezinto Zocansi

Umbhali: Synwin– Umatilasi Wangokwezifiso

Isimo sokuxhumana phakathi komatilasi nomzimba womuntu sizothinta ukunethezeka okucatshangwayo komzimba womuntu futhi sithinte nakakhulu ikhwalithi yokulala. Kungenzeka ukuthi kube yimbangela eqondile yezilonda zengcindezi ezigulini ezihlala isikhathi eside zilele embhedeni. Ngo-1998, u-Peter no-Avalino [1] bafunda omatilasi besebenzisa ukuhlolwa komfutho womzimba womuntu kanye nokuhlola okuzimele kokunethezeka, futhi imiphumela yabonisa ukuthi omatilasi abahloliwe babenokunethezeka okungcono kunezindawo zamapulangwe ezingenakucindezelwa. Ngo-1988, u-Shelton[2] uhlongoze inkomba yengcindezi (i-Pindex) ngenani elikhulu lokuhlaziywa kwedatha lapho kuhlanganiswa isilinganiso esimaphakathi sokucindezela, ukuphakama kokucindezela, ukuphakama kokucindezela okukhulu nezinye izici, futhi kuqhathaniswe nomphumela wokuhlola ukuwohloka komatilasi, okubonisa ukusebenza okuhle kakhulu. ukungaguquguquki okuhle.

Ngo-2000, i-Defloor[3] yenza ucwaningo ngethonya lezindawo zokulala ezihlukene kungcindezi kamatilasi. Ucwaningo lubonise ukuthi ukuma okungu-30° kokuhlala kancane kanye nendawo ethambekele kunengcindezi encane endaweni ethinta umatilasi, kuyilapho uhlangothi olulele ngo-90° lunengcindezi ephansi kakhulu kumatilasi. Okukhulu kunakho konke, okuphinde kwatholakala ukuthi kusebenzisa umatilasi wegwebu ojwayelekile, kunciphise ukucindezela kokusebenzelana ngamaphesenti angama-20 kuye kwangama-30. Ngo-2000, u-Bader [4] wenza ucwaningo ngobudlelwano phakathi kwekhwalithi yokulala nobulukhuni bombhede, futhi wathola ukuthi abantu abaningi babekwazi kangcono ukuzivumelanisa nomatilasi othambile kunomatilasi oqinile. Ngo-2010, uJacobson et al. [5] wenze ucwaningo ezigulini ezinobuhlungu obuncane obuphansi emuva noma ukuqina. Ucwaningo luthole ukuthi ukuxhumana nomzimba womuntu ngesikhathi sokulala kunomthelela kukhwalithi yokulala. Ukushintsha umatilasi oqinile kungathuthukisa ukungakhululeki kokulala futhi kukhulule ukhalo lwesiguli. Ubuhlungu beqolo nokuqina.

Eminyakeni yamuva nje, izazi zaseShayina ziphinde zandisa ucwaningo lwazo ngomatilasi, futhi umzimba oyinhloko usabonakala ebudlelwaneni obuphakathi kokunethezeka komatilasi, izinga lokulala, ukujiya kukamatilasi, kanye nezakhiwo zezinto ezibonakalayo. Ngo-2009, uLi Li et al. [6-7] yakala inkomba yokusabalalisa ingcindezi yomzimba womzimba womuntu ngokushintsha ukushuba kwesipontshi ebusweni bukamatilasi, futhi yenza ukuhlaziya okujulile kokuzithoba kanye nenhloso, yathola ukuthi ukushuba kwesipontshi kunomthelela obalulekile ekunethezekeni komatilasi. Ngo-2010, kwakhethwa izinhlobo ezihlukene zoomatilasi bezipontshi, futhi umthelela wezinhlobo zesipontshi ekunethezekeni okuphelele nendawo komzimba womuntu kwahlaziywa futhi kwaqhathaniswa.

Ngo-2014, lapho u-Hou Jianjun [8] efunda umthelela wezinto zikamatilasi ezicini zomzimba womuntu osendaweni engemuva, wathola ukuthi indawo yokuxhumana phakathi komatilasi nomzimba womuntu inkulu, futhi ukuthintana isikhathi eside kungaholela kalula ekukhathaleni komuntu. Kungabonakala kulokhu okungenhla ukuthi ucwaningo kumatilasi ikakhulukazi lulele ekuhlolweni kokusabalalisa ingcindezi, futhi lukhawulelwe ezintweni ezithile. Izindlela zokuhlola inhloso zomphumela wokusekela wezisetshenziswa zikamatilasi azivamile uma kuqhathaniswa.

Kuleli phepha, kukhethwa izinto ezijwayelekile zikamatilasi eziyisi-6, kanti kuzo kwenziwa ukuhlolwa kokucindezelwa ngakugqinsi kanye nokuhlolwa kokusabalalisa ingcindezi yomzimba womuntu. Umthelela osekelayo wezinto zikamatilasi. 1 Indlela yokuhlola Kwakhethwa umfundi wasekolishi wesifazane ophile kahle ukuze ahlolwe. Lesi sihloko sasingenawo umlando wesifo se-musculoskeletal, sasineminyaka engu-24 ubudala, sasingu-165 cm ubude, futhi sinesisindo esingu-55 kg. Izinto ezikhethiwe kulokhu kuhlolwa isipontshi esijwayelekile, igwebu lenkumbulo, isipontshi esiqondile, ukuminyana okubili okuhlukene kwegwebu lesifutho kanye nezinto ezi-3D. Ukusebenza kokucindezelwa kwezinto zikamatilasi kwahlolwa kusetshenziswa umshini wokuhlola impahla we-American Instron-3365, osetshenziselwa kakhulu ukuqinisa izinto ezibonakalayo. Ukuhlolwa kwe-elongation.

Ukuze kuhlolwe izakhiwo zokucindezelwa zezinto zikamatilasi, ipheya lamapuleti ensimbi ayisikwele angu-10cm×10cm aye anamathiselwe kuma-chucks angaphezulu naphansi ngokulandelana ukuze kubonwe ukuhlolwa kokucindezela. Okubalulekile kukamatilasi kusikwa kube isilinda onobubanzi obungu-6.6mm, kubekwe epuletini lokuhlola elingezansi, ipuleti lensimbi eliphezulu licindezela kancane kancane okokusebenza kukamatilasi liye phansi, futhi limise ukucindezelwa lapho ukujiya kungu-5mm, futhi lirekhoda ingcindezi kusukela ekuqaleni kokuminyanisa kuze kube sekupheleni kokuhlolwa. . Ukuhlolwa kokusabalalisa ingcindezi yomzimba kusebenzisa uhlelo lokuhlola ukunethezeka kokugqoka lwe-Japan AMI Company.

Idivayisi isebenzisa inzwa yokucindezela yohlobo lwebhaluni, eqoqa idatha njalo ngamasekhondi angu-0.1 phakathi nokuhlolwa. Ngokuhlolwa kokusabalalisa ukucindezela komzimba, izingxenye ze-6 ze-vertebra yomlomo wesibeletho yesikhombisa, ihlombe, emuva, umlenze, ithanga kanye nethole zikhethiwe ukuze zihlolwe, futhi izinzwa ze-airbag ezinobubanzi obungu-20 mm zifakwe endaweni ngayinye yokuhlola. Umhloli ulala phansi kumatilasi, futhi lapho idatha yengcindezi izinza, idatha irekhodwa amaminithi angu-2.
