Yakawedzera

Kuchinjika HINGES kwakawana kutarisisa kwakakosha mumidziyo chaiyo nekuda kwekugona kwavo kuendesa mafambiro kana simba kuburikidza neElastic deformation panzvimbo yezvinhu zvakaomarara. Kuenzaniswa neyechinyakare kwekufamba kwekufamba, maruva anochinjika anopa zvakanakira zvakadai sekugadziriswa kwakanyanya, hapana kupokana, hapana mishonga, uye maitiro akareruka. Ivo vakave vakashandiswa zvakanyanya mumidziyo yakasarudzika, kusanganisira projekiti lithography chinangwa, silicon waferbenches, magetsi ekutarisa microscopes, nzvimbo yekusagadzikana kure, uye chaiyo-chaiyo-yekugadzirisa. Iyo yakakosha paramita yemabatirwo emakambani, senge inochinjika hinges, zvakananga zvinokanganisa hunhu hune simba uye kumisikidza chokwadi cheMugumo. Naizvozvo, tsvakiridzo yakawandisa yakaitwa kuti unzwisise kuchinjika kwemhenderekedzo yekuchinjika. Iri pepa rinovavarira kudzidza matrix inochinjika yemakwenzi yakatwasuka yakatenderedzwa nzira yekuchinjika, ongorora parmeter yayo, uye ipa hwaro hwekugadzira uye kuronga.

Kuchinjika Matrix kweNzvimbo Yakananga Deam inotenderera yakashanduka maHinge:

Iyo yakatwasuka yakatwasuka yakatenderedzwa kuti ishanduke hinge yeiyo yakananga yebheji sheet svina yakakomberedzwa pamakona ehusiku kuti adzivise kushushikana kushushikana. Iyo main geometric paramita inosanganisira hingee hine hei hine, hinge urefu (l), hingepness (t), uye hinge fillet radius (r). Kuti uongorore kusvibiswa-ndege yekushambadzira, iyo yekuongorora yekuverenga nzira yakavakirwa pane iyo cantilever bey rondedzero inotorwa. Iyi nzira inogadza iyo yakavharwa-loop eruongorora muenzaniso kune iyo-ndege inoshanduka matsaru weiyo inoshanduka. Pamusoro pezvo, fomu Rakareruka Colculation yeiyo nzira yekuchinjika inopihwa kana iyo chiyero chekona yekona yekona radius kusvika kumusoro (r / t) inopiwa.

Kuverengera Element Element:

Kuti usimbise iyo inotorwa imbet yekuongorora formula, mhando yemhando yepamusoro yeiyo yakatwasuka danda rakakomberedzwa nendege yakasimbiswa uchishandisa UGNX Nastran Software. Iyo yekufungidzira mhedzisiro yeiyo yakasimudzwa muenzaniso modhi inoenzaniswa neyekuongororwa kukosha kwekuchinjika kwematram azasi. Kanganiso yechipiri pakati pevaviri vanoongororwa zvakasiyana siyana mumapepa ehudyu mune hinge's maratari, akadai sechiitiko chehurefu hwehukadzi

Mhedzisiro:

Ongororo yacho inoratidza kuti yeL / T ratos yakakura kupfuura kana yakaenzana ne4, kukanganisa kwekadzi pakati peiyo yekuongorora matsaru ari mukati 5.5%. Nekudaro, nekuda kweL / T ratios isingasviki 4, kukanganisa kweimwe hama kwakakura nekuda kwekutadza kurerutsa iyo cantilever beam mugwatuni anoponesesa. Izvi zvinoratidza kuti iyo yakavharwa-loop imbiso modhi yakanyanya kukodzera kune ma kesi eL / t.

Pamusoro peiyo ratio r / t, kuongorora kunoratidzira kuti kana 0.1 ≤ r / t Pamusoro pezvo, kana 0.2 ≤ r / t ≤ 0.3, kukanganisa kwehama kunogona kudzorwa mukati 6.5%. Izvi zvakawanikwa zvinoratidza chokwadi uye chishandiso cheiyo yakavharwa-loop imbiso modhi yekuchinja-chinja matrix.

Iyo yakavharwa-loop imbiso modhi yakagadziridzwa mune ino chidzidzo inopa hwaro hwaro hwekugadzira uye kurerutswa kweiyo yakatwasuka gomba rakakomberedzwa. Ongorora ongororo dzakaratidza kuti muenzaniso unogona kufanotaura nenzira chaiyo matsramita kana uchifunga zvakasiyana mukureba kwenguva yakareba, ukobvu, uye kona radius. Izvi zvakawanikwa zvichabatsira mukufambisira mberi kwemabatirwo emakambani uye mafomu avo mumidziyo chaiyo.
