Ucango lwangasemva lwesakhiwo sehenjisi yoyilo scheme_hinge ulwazi 4

1.

Iprojekthi yombane wokukhanya womzimba obanzi yinzame entsha kunye nedatha, ngokugxila kwimigaqo yoyilo lwangaphambili. Kuyo yonke iprojekthi, imodeli yedijithali idibanisa ngaphandle komthungo ubume kunye nolwakhiwo, ukusebenzisa izibonelelo zedatha yedijithali echanekileyo, ukuguqulwa okukhawulezayo, kunye nojongano olugudileyo kunye noyilo lolwakhiwo. Ngokubandakanya uhlalutyo lokwenzeka kwesakhiwo kwinqanaba ngalinye, injongo yokuphumeza imodeli enokwenzeka ngokwesakhiwo kunye neyonelisayo ebonakalayo inokuphunyezwa kwaye yabelwane ngokulula ngendlela yedatha. Ke ngoko, ukuhlolwa kwembonakalo Uluhlu lwe-analog yedijithali yeCAS ibalulekile kwinqanaba ngalinye. Kweli nqaku, siza kuhlolisisa uhlalutyo olucacileyo loyilo lwehinge yomnyango ongasemva.

2. Ulungiselelo lwe-axis yocango lwangasemva

Inxalenye ephambili yokuhlalutya intshukumo yokuvula yi-hinge axis layout kunye nokumiselwa kwesakhiwo se-hinge. Ukuze uhlangabezane neemfuno zesithuthi, umnyango ongasemva kufuneka ukwazi ukuvula i-270 degrees. Ukongeza, ihenjisi kufuneka igungxulwe nomphezulu we-CAS kunye ne-angle yokuthambekela efanelekileyo.

Amanyathelo okuhlalutya kwi-hinge axis layout ngolu hlobo lulandelayo:

a. Qinisekisa indawo ye-Z-direction ye-hinge ephantsi, ngokuqwalasela indawo efunekayo yokulungiswa kweplate yokuqinisa, kunye neenkqubo ze-welding kunye nendibano.

b. Lungiselela icandelo eliphambili le-hinge ngokusekelwe kwindlela emiselweyo ye-Z ye-hinge ephantsi, ngokuqwalasela inkqubo yofakelo. Qinisekisa izikhundla ze-axis ezine ze-four-link ngokusebenzisa icandelo eliphambili kunye ne-parameterize ubude beekhonkco ezine.

c. Misela ii-axes ezine ngokubhekisele kwi-engile yokuthambekela kwe-hinge axis ye-benchmark yemoto. Parameterize amaxabiso e-axis inclination kunye nokuthambekela phambili usebenzisa indlela ye-conic intersection.

d. Qinisekisa indawo yehenjisi ephezulu ngokusekwe kumgama ophakathi kweehenjisi eziphezulu nezisezantsi zemoto yokulinganisa. Iparameterize umgama phakathi kweehenjisi kwaye umisele iindiza eziqhelekileyo zee-axes zehinge kwezi zikhundla.

e. Cwangcisa amacandelo aphambili eehenjisi eziphezulu kunye nezisezantsi kwiinkcukacha kwiindiza eziqhelekileyo ezimiselweyo, kuthathelwa ingqalelo ukulungelelaniswa kwe-flush yehinge ephezulu kunye ne-CAS surface. Qwalasela ukuveliswa, ucoceko olufanelekileyo, kunye nesithuba sesakhiwo sendlela yonxibelelano yeebha ezine ngexesha lenkqubo yoyilo.

f. Ukuqhuba uhlalutyo lwentshukumo ye-DMU usebenzisa i-axes ezimiseleyo ukuhlalutya ukunyakaza kocango lwangemva kwaye ujonge umgama wokhuseleko emva kokuvula. Ijika lomgama lokhuseleko lwenziwa ngoncedo lwemodyuli yeDMU.

g. Ukuqhuba uhlengahlengiso lweparametric, ukuhlalutya ukwenzeka kokuvula umnyango ongasemva ngexesha lenkqubo yokuvula kunye nomda wokhuseleko lokubeka umda. Ukuba kuyimfuneko, lungisa umgangatho we-CAS.

Uyilo lwe-hinge axis lufuna imijikelo emininzi yohlengahlengiso kunye nokutshekishwa kokuqinisekisa iziphumo ezilungileyo. Nje ukuba i-axis ihlengahlengiswe, uyilo olulandelayo malulungiswe ngokufanelekileyo. Ke ngoko, i-hinge axis layout kufuneka ihlalutywe ngobuchule kwaye ilinganiswe. Nje ukuba i-hinge axis imiselwe, uyilo oluneenkcukacha lwehinge lunokuqalisa.

3. Iskimu soyilo lwehinge yocango lwangasemva

Ihenjisi yocango olungasemva isebenzisa indlela yonxibelelaniso enemivalo emine. Ukuqwalasela uhlengahlengiso kwimilo xa kuthelekiswa nemoto yokulinganisa, ulwakhiwo lwehinge lukwafuna uhlengahlengiso olubalulekileyo. Ukunikezelwa kwezinto ezininzi, iinketho ezintathu zoyilo lwesakhiwo sehenjisi ziyacetywa.

3.1 isicwangciso 1

Ingcamango yokuyila: Qinisekisa ukuba iihenjisi eziphezulu kunye nezisezantsi zihambelana nomphezulu we-CAS kwaye zitshatise umgca wokwahlula. I-hinge axis: i-1.55 degrees ngaphakathi kunye ne-1.1 degrees phambili.

Ukungalungi kokubonakala: Xa umnyango uvaliwe, kukho umahluko obonakalayo phakathi kwe-hinge kunye nezikhundla ezihambelana nomnyango, ezinokuchaphazela umphumo wokuvala umnyango ngokuzenzekelayo.

Ubuhle bembonakalo: Umphandle wangaphandle weehenjisi eziphezulu kunye nezantsi zigungxulwa kunye ne-CAS surface.

Imingcipheko yesakhiwo:

a. Uhlengahlengiso kwihinge axis inclination angle inokuba nefuthe kwisiphumo sokuvala ucango oluzenzekelayo.

b. Ukwandisa iintonga ezidibanisayo zangaphakathi nangaphandle zehenjisi kunokubangela ukuhexa kocango ngenxa yokungonelanga kwamandla ehenjisi.

c. Iibhloko ezahluliweyo kudonga olusecaleni lwehinji ephezulu zinokukhokelela kubunzima bokuwelda kunye nokuvuza kwamanzi okunokwenzeka.

d. Inkqubo yokufakela ihenjisi embi.
