Ithuluzi lokulinganisa amaphuzu e-3DH lisetshenziselwa ukusungula amaphuzu ayireferensi esakhiweni sangaphakathi semoto nobukhulu besikhala sabagibeli, nokuqinisekisa izindawo nobukhulu bomzimba balawa maphuzu abalulekile ayireferensi ngesikhathi sokuhlola.
    I-H-point ibhekisela enkabeni yokujikeleza phakathi kwethanga lomuntu nesifuba; kudivayisi ye-H-point ye-3D, ibhekisela endaweni yokuxhumana phakathi kwecushion yesihlalo nomhlane wesihlalo. Indawo ye-H-point esihlalweni semoto inomthelela omkhulu ekunqunyweni kwamaphoyinti ayisisekelo abalulekile nobukhulu bendawo ngaphakathi kwemoto, futhi ithinta ngqo ukunqunywa kwe-R-point kanye nokuphepha nokunethezeka kwabagibeli bemoto. Ekuhlolweni kokuphahlazeka kwezimoto, izihlalo zomhlane nezihlalo zama-dummy okuhlola ezisetshenziswa ekuhlaziyweni kokuphahlazeka nazo zixhunywa e-H-point; ukunquma indawo ye-H-point yesihlalo kuyisidingo sokuqala sokufakwa kahle kwe-dummy. Ngakho-ke kubaluleke kakhulu ukukwazi ukumaka indawo ye-H-point ezihlalweni zemoto ngokunembe nangokulula, nokusebenzisa idivayisi ye-H-point ye-SAE J826 enobukhulu obuthathu ngendlela efanele.
  Ekwakhiweni kwezimoto nasekuqinisekisweni kobunjiniyela, i-H-point (indawo ye-hip) iyipharamitha eyinhloko yokuklama izihlalo nokuhlelwa kwe-ergonomic, ethinta ngqo ukubona komshayeli, ukunethezeka kokusebenza, nokuphepha. Njengethuluzi elijwayelekile lokulingisa ukuhlala komuntu, ithuluzi lokulinganisa i-H-point lezimoto—elakhiwe ngokuhambisana nezinga le-SAE J826 lomhlaba wonke—linikeza abakhiqizi bezimoto idatha enembile yokubeka i-H-point, okwenza kube ithuluzi elibalulekile ekuthuthukiseni izihlalo nasekuhleleni ukwakheka kwe-cockpit.
I. Izimiso Zobuchwepheshe Nezingxenye Eziyinhloko
Kuklanywe ngokuya ngezinga le-SAE J826, le modeli yedummi ilingisa uhlaka lwamathambo omshayeli wesilisa omdala esimweni sokuhlala, igxile kakhulu ekukhiqizeni ngokunembile indawo ye-hip joint (i-H-point). Umzimba wayo oyinhloko wakhiwe ngensimbi engagqwali ne-aluminium, kanti uhlaka lwamathambo lwenziwe nge-aluminium alloy enamandla kakhulu ukuze kuqinisekiswe ukuthi ayihlanekezeli ngesikhathi sokusetshenziswa isikhathi eside. Ama-bearing anembile asetshenziswa ezindaweni zokuxhuma, okuvumela ukulungiswa okuguquguqukayo kwama-engeli okuhlala (njenge-engeli yomhlane nengeli yokubeka imilenze) ukuze kulingiswe izimo zomzimba wezimo ezahlukene zokushayela. Ingaphezulu lemodeli limbozwe ngegobolondo leplastiki eliqinile elinemigqa ecacile yokukhomba izinkomba, ukuze kube lula ukuqondanisa nesistimu yezixhumanisi zemoto ngesikhathi sokulinganisa.
II. Inqubo Yokuyisebenzisa Nokulinganisa
Ukuze usebenzise imodeli, iqinise esihlalweni semoto bese uyilungisa ukuze ibe sesimweni esijwayelekile sokushayela (isb., izandla zombili zisesiteringini, izinyawo zombili zisephedalini). Bese, sebenzisa i-laser tracker noma umshini wokulinganisa izixhumanisi (CMM) ukuze uthole izixhumanisi ze-H-point. Izinyathelo eziqondile zimi kanje: 1. Qinisa isisekelo se-mannequin, uqinisekise ukuthi sihambisana nendawo yokuthintana nesihlalo; 2. Lungisa amalunga ukuze abe ema-engeli ahlosiwe bese uwakhiya endaweni; 3. Xhuma imishini yokulinganisa bese urekhoda idatha ye-3D yephoyinti H kusistimu yezixhumanisi zemoto; 4. Qhathanisa imiphumela namavelu okuhlosiwa okuklanyiwe ukuze uqinisekise ukuthi indawo yesihlalo iyahambisana nezidingo ze-ergonomic. Ukuphazamiseka kwangaphandle kwe-vibration kufanele kugwenywe ngesikhathi sokulinganisa ukuze kuqinisekiswe ukunemba kwedatha.
III. Izinzuzo Zobuchwepheshe Nokubaluleka Kwemboni
Uma kuqhathaniswa nezindlela zokulinganisa zendabuko (ezifana nokumaka ngesandla namamodeli angakabi namthetho), i-dummy esezingeni le-SAE inikeza izinzuzo ezintathu ezinkulu: Okokuqala, umklamo wayo osezingeni elimisiwe ususa ukwehluka phakathi kwabantu, okwenza kube nokwenzeka ukuqhathanisa idatha; okwesibili, amalunga ayo anemba aphezulu alingisa ububanzi bangempela bokunyakaza komuntu, evimbela amaphutha abangelwa ukuchezuka kokuma komzimba; okwesithathu, ukwakhiwa kwayo ngensimbi kuqinisekisa ukuqina okuphezulu, okwenza ifanelekele ukusetshenziswa kaningi ezindaweni zokuhlola zaselabhorethri. Njengamanje, le modeli isetshenziswa kabanzi ekuthuthukisweni kwezihlalo zezimoto, ekubekweni kwama-airbag, nasekukalweni kwe-field-of-view, isiza abakhiqizi bezimoto ukunciphisa imijikelezo yocwaningo nokuthuthukisa nokunciphisa ubungozi bokukhumbula okubangelwa amaphutha e-ergonomic.
IV. Izimo Zokusetshenziswa Ezinwetshiwe
Ngaphandle kwemboni yezimoto, la mamodeli okulingisa angasetshenziswa nasemikhakheni efana nokuklanywa kwezihlalo zezitimela kanye nokuthuthukiswa kokuhlelwa kwekhabethe lendiza. Isibonelo, ekuthuthukisweni kwezihlalo zezitimela ezinesivinini esikhulu, ukulungisa amapharamitha obukhulu be-dummy (njengobude nesisindo) kuvumela ukuqinisekiswa kokunethezeka kwabagibeli bezinhlobo ezahlukene zomzimba; ekuhlolweni kwesilayidi esiphuthumayo sendiza, ama-dummy angalingisa izimo zokwehla kwabagibeli ukuze kuhlolwe ukuthi impahla iyafinyeleleka yini. Ukuklanywa kwazo okuhlukanisekayo—njengezingxenye zemilenze ezingashintshwa—kukhulisa kakhulu ububanzi bokusetshenziswa kwazo, kuhlangabezane nesidingo samamodeli abantu ajwayelekile emikhakheni eminingi.
