Ucango lwangasemva lwesakhiwo sehenjisi yoyilo scheme_hinge ulwazi 1

1.

Ukuphuhliswa kweprojekthi yombane obanzi wokukhanya yidatha eqhutywa kwaye iyilwe phambili. Kuyo yonke iprojekthi, imodeli yedijithali idibanisa ngaphandle komthungo ubume kunye nolwakhiwo, ithatha inzuzo yedatha yedijithali echanekileyo, ukuguqulwa okukhawulezayo, kunye nojongano olungenamthungo kunye noyilo lolwakhiwo. Ibandakanya uhlalutyo olunokwenzeka kwinqanaba ngalinye, iqinisekisa imodeli enokwenzeka ngokwesakhiwo neyanelisayo. Eli nqaku ligxile kukubaluleka kokuhlola imbonakalo ye-CAS yedijithali ye-analog CheckList kwinqanaba ngalinye kwaye libonelela ngokujonga nzulu kwinkqubo yokuvula ihenjisi ngasemva.

2. Ulungiselelo lwe-axis yocango lwangasemva:

Into ephambili yokuhlalutya kwentshukumo yokuvula kukucwangcisa i-hinge axis kunye nokuzimisela kwesakhiwo se-hinge. Umnyango ongasemva wesithuthi kufuneka uvule i-degrees ezingama-270 ngelixa ugcina ukulungelelaniswa kwe-flush kunye ne-CAS surface kunye nokuqinisekisa i-angle ye-hinge axis inclination angle efanelekileyo.

Amanyathelo okuhlalutya kwi-hinge axis layout ngolu hlobo lulandelayo:

a. Misela indawo ye-Z-direction ye-hinge ephantsi, ngokuqwalasela zombini indawo efunekayo yokulungiswa kweplate yokuqinisa kunye ne-welding kunye nobukhulu benkqubo yendibano.

b. Lungiselela icandelo eliphambili le-hinge esekelwe kwi-Z-direction position ye-hinge ephantsi, ngokuqwalasela inkqubo yokufakela kunye nokumisela izikhundla ezine ze-axis ezine kunye ne-parameterization.

c. Qwalasela ii-engile zokuthambekela kwee-asi ezine ezisekelwe kwi-engile yehinge yehinge yemoto, usebenzisa indlela ye-conic intersection yeparameterization.

d. Qinisekisa indawo yehenjisi ephezulu ngokubhekiselela kumgama ophakathi kweehenjisi eziphezulu nezisezantsi zemoto yokulinganisa, kunye ne-parameterization yomgama phakathi kweehenjisi kunye nokudalwa kweenqwelo-moya eziqhelekileyo kwezo ndawo.

e. Ukucwangciswa kweenkcukacha zamacandelo aphambili eehenjisi eziphezulu kunye nezisezantsi kwiinqwelo-moya eziqhelekileyo ezimiselweyo, kuqwalaselwa ukufakela, ukwenziwa kwezinto, ukucoceka okufanelekileyo, kunye nendawo yesakhiwo.

f. Yenza uhlalutyo lwentshukumo ye-DMU usebenzisa i-axes ezine ezimiselweyo ukuhlalutya ukunyakaza komnyango ongasemva kwaye ukhangele umgama wokhuseleko ngexesha lokuvula.

g. I-Parametrically lungisa iiseti ezintathu ze-hinge axis parameters ukuhlalutya ukuba nokwenzeka kokuvula umnyango ongasemva. Ukuba kuyimfuneko, lungisa umgangatho we-CAS.

I-hinge axis layout ifuna imijikelo emininzi yohlengahlengiso kunye nokutshekisha ukuqinisekisa ukuba ihlangabezana ngokupheleleyo neemfuno. Naluphi na uhlengahlengiso luya kufuna uhlengahlengiso olulandelayo lwesakhiwo, lugxininisa ukubaluleka kohlalutyo olucokisekileyo kunye nolungelelwaniso.

3. Iskimu soyilo lwehinge yocango lwangasemva:

Ihenjisi yocango lwangemva isebenzisa indlela yonxibelelaniso enemivalo emine, kwaye iindlela ezintathu zoyilo ziyacetywa. Inketho nganye ineengenelo kunye nokungona kwayo.

3.1 isicwangciso 1:

Esi sikimu sijolise ekufaniseni iihenjisi eziphezulu kunye nezantsi kunye ne-CAS surface kunye nokufezekisa ukuhambelana nomgca wokuhlukanisa. Nangona kunjalo, inenkangeleko yokungalungi, njengomahluko omkhulu phakathi kwendawo ehambelana nehenjisi kunye nocango xa luvaliwe.

3.2 isicwangciso 2:

Kwesi sikimu, zombini iihenjisi ezingasentla nezisezantsi ziphumela ngaphandle ukuqinisekisa ukuba akukho msantsa ofanelekileyo phakathi kweehenjisi kunye nomnyango ongasemva kwicala le-X. Olu khetho lunikeza izibonelelo zesakhiwo, ezifana nokugcinwa kweendleko ngenxa yeehenjisi eziqhelekileyo kunye nenkqubo efanelekileyo yokuhlanganisa.

3.3 isicwangciso 3:

Umphandle wangaphandle weehenjisi eziphezulu kunye nezantsi zihambelana kakuhle ne-CAS surface kule skimu. Nangona kunjalo, kukho umsantsa omkhulu phakathi kwekhonkco locango oluxhonyiweyo kunye nekhonkco langaphandle, kwaye ukufakela kunokuba ngumngeni.

Emva kokuhlalutya ngokucokisekileyo kunye nengxoxo, "isisombululo sesithathu" siqinisekiswa njengesona sisombululo sisona sisona sifanelekileyo ngenxa yotshintsho lwalo oluncinci kumphezulu wangaphandle, ukugcina ukuhambelana kwimodeli.
