Cwaninga ngesisekelo se-theoretical of design ukwenziwa kwama-hinges aguqukayo kanye nezindlela zomzimba eziguqukayo

Andisiwe

Ama-hinges aguquguqukayo athole ukunakwa okubalulekile kumadivayisi anembile ngenxa yamandla abo okudlulisa ukunyakaza noma amandla ngokulimala okubanzi esikhundleni sezakhi eziqinile. Uma kuqhathaniswa nama-hinge e-Motion Motion, ama-hinges aguqukayo anikela ngezinzuzo ezinjengokulungiswa kokuhamba okuphezulu, akukho ukungqubuzana, akukho inqubo elula yokukhiqiza. Basetshenziswe kabanzi kumadivayisi ahlukahlukene okunemba, kufaka phakathi ama-Projection Lithophy lens, ama-Silicon Wafer Workbenches, ama-microscopes askena ama-Microscopes, izinzwa ezikude zesikhala, nokunemba nokunemba okunembayo kanye nokunemba okunembayo kanye nokunemba okunembayo kanye nokunemba okunembayo kanye nokunemba okunembayo kanye nokunemba okunembayo kanye nokunemba okunembayo kanye nokunemba okunembayo nokunemba. Amapharamitha asemqoka ezihlangene ezitholwayo, njenge-hinges eguqukayo, zithinta ngqo izici ezinamandla nokubeka ukunemba kokuphela. Ngakho-ke, ucwaningo olunzulu lwenziwe ukuze uqonde ukuguquguquka kwezimo eziguqukayo. Leli phepha lihlose ukutadisha i-matrix eguquguqukayo yogongolo oluqondile olujikelezayo izihibe izihibe, hlaziya amapharamitha alo, futhi linikeze ngesisekelo sethiyori sokuqamba kanye nokwenza kahle kwalo.

I-Matrix yokuvuselelwa kwezindlela eziqondile ze-beam ezijikelezayo ezihlanganisiwe:

Ugongolo oluqondile lokuhlobisa oluyindilinga luqukethe isakhiwo sephepha le-beam eliqondile ngamakhona ayindilinga ezindaweni zokugcina ze-hinge ukugwema ukugxilisa ingcindezi. Amapharamitha asemqoka wejometri afaka i-Hinge Height (H), ubude be-hinge (L), ubukhulu be-hinge, kanye ne-hinge fillet radius (r). Ukuhlaziya i-defformation ye-in-indiza ye-hinge, indlela yokubala yokuhlaziya ngokususelwa ku-cantilever beam theory ithathwe. Le ndlela isungula imodeli yokuhlaziya evaliwe ye-Loop ye-matrix ye-in-pelane ye-matrix ye-hinge eguquguqukayo. Ngokwengeziwe, ifomula yokubala eyenziwe lula ye-matrix yokuguquguquka i-matrix eguqulwa lapho kunikezwe isilinganiso se-Hinge Corner Radius (R / T).

Ukuqinisekiswa kwe-Element:

Ukuze uqinisekise ifomula yokuhlaziya ethathwe, imodeli ye-ONET EYITE ye-BEAM eyindilinga eyindilinga ye-House Imiphumela yokulingisa yemodeli ye-Fination yesehlakalo iqhathaniswa namanani wokuhlaziya ezinhlelo ze-matrix eziguqukayo. Iphutha elihlobene phakathi kwalaba bobabili lihlaziywa ngokuhlukahluka okuhlukile kumapharamitha we-hinge, njengesilinganiso sobude be-hinge ukuze ubukhulu (l / t) kanye nesilinganiso se-hinge ekhoneni radius ukushuba (R / T).

Umphumela:

Ukuhlaziywa kukhombisa ukuthi izilinganiso ze-L / T zikhulu noma zilingana no-4, iphutha elihlobene phakathi kwamanani wokuhlaziya kanye namanani we-matrix aguquguqukayo angakapheli ama-5.5%. Kodwa-ke, ngezilinganiso ze-L / T ezingaphansi kwe-4, iphutha elihlobene nalo likhulu ngenxa yokungakwazi ukwenza lula ugongolo lwe-cantilever emgodini omncane. Lokhu kukhombisa ukuthi imodeli yokuhlaziya evaliwe ye-Loop ilungele amacala amakhulu we-L / T.

Mayelana nesilinganiso R / T, ukuhlaziywa kwembula ukuthi lapho u-0.1 ≤ / r / t ≤ 0.5, iphutha elihlobene phakathi kwamanani wokuhlaziya nelilingiswa lingalawulwa kungakapheli amanani angu-9%. Ngokwengeziwe, lapho u-0.2 ≤ R / t ≤ 0.3, iphutha elihlobene lingalawulwa kungakapheli ama-6.5%. Lokhu okutholakele kukhombisa ukunemba nokusebenza kwemodeli yokuhlaziya evaliwe ye-matrix yokuguquguquka.

Imodeli yokuhlaziya evaliwe yokwehla ithuthukiswe kulolu cwaningo ihlinzeka ngesisekelo sethiyori sokwakhiwa nokwenza kahle kogongolo oluqondile lokugoqa izimpungushe. Ukuhlaziywa kwakhombisa ukuthi imodeli ingabikezela ngokunembile amapharamitha we-matrix yokuguquguquka lapho ucabanga ngokuhlukahluka ngobude be-hinge, ubukhulu, kanye nomsakazo wegumbi. Lokhu okutholakele kuzoba nomthelela ekuthuthukisweni kwezindlela ezihambisana nokuthobela kanye nezicelo zazo kumadivayisi anembile.
