Imodeli ye-kinematic kunye nophando lwentsebenzo ye-zero stuffness quid facked hinge -ung

Indlela yokutshintsha ingcinga eqhumayo kwintsimi yoomatshini, njengoko isebenzisa ukuthotyelwa kwezinto ze-elastic ukwadlulisa intshukumo, amandla, okanye amandla. Le ndlela ifumene ukuthandwa kumashishini ahlukeneyo, kubandakanya ukubeka phambili, ukulungiswa kweMS, kunye nee-aerospace, ngenxa yeenzuzo zalo ezifana nokusebenza kwayo, ukugcinwa okulula, ukulungiswa okuphezulu, kunye nokulungiswa okuhlanganisiweyo.

Nangona kunjalo, iindlela zemveli zemveli zisalawula imarike ngenxa yokusikelwa kwemida ethile yendlela eguqukayo. Enye yezi sithintelo kukuqina okuqinisekileyo okwenzekayo kwindawo esebenzayo ngexesha lesenzo sendlela. Olu lukhuni oluqinisekileyo lufuna amandla amakhulu okuqhuba kunye neemfuno ezingqongqo kumqhubi, othi ekugqibeleni unciphisa ukuhanjiswa kwamandla. Ezi ntsilelo zithintele ukusetyenziswa ngokubanzi kwendlela eguqukayo.

Ukoyisa iziphumo ezibi kakhulu, uninzi lwabaphengululi bazise umxholo we-zero oluqhophololo kwindlela eguqukayo. Ngobuqili besebenzisa ukomelela okungalunganga ukucima ukuqina kokuqina, indlela ene-zero olutyeqoko kunokufezekiswa. Inkqubo enjalo, ekwabizwa ngokuba yinkqubo yokulinganisa eguqukayo ye-Static, inokufezekisa imeko yokulingana ne-statifilib ngapha nangayiphi na indawo kuluhlu lwentshukumo. Olu hlobo lwendlela lubonelela ngeenzuzo ezininzi, kubandakanya umsebenzi obalaseleyo wokuhambisa, amandla okusebenza kunye nemikhosi emincinci yokuqhuba, kunye nokusebenza okuphezulu kwamandla amandla. Ngenxa yoko, ukugxila kophando kwicandelo leendlela ze-statives eziguqukayo ikakhulu ikakhulu zikwiicoci ezincinci eziguquguqukayo.

Phakathi kwamacandelo ahlukeneyo eendlela eziguqukayo, i-hinges eguqukayo ifumene ingqalelo enkulu ngenxa yeempawu zabo ezizodwa. Ukuhamba kwesihlobo se-hindus-jikelele esiguquguqukayo sifutshane ngokufutshane, sibenza baxabiseke kakhulu kwizicelo ezibanzi. Ngenxa yoko, i-zero-timed hinge eguquguqukayo esekwe kolu uyilo luye lolona khetho lukhethiweyo lokwakha iindlela zokulinganisa eziguqukayo, zenza uphando lwayo lubaluleke kakhulu.

Ukufezekisa iimpawu zokuqinisa izinto ezilukhuni ezikwi-hindus eziguquguqukayo, kuyafuneka ukucima ukuqina okuqinisekileyo kwe-torsional kunye nokuqina okungalunganga. Kule meko, kwenziwe imodeli yobutyebi obuqinileyo. Imodeli ibandakanya ukusebenzisa igqabi lemithombo equlunqa ingqokelela emibini yokuqhubela phambili, enye ilungisiwe kwaye enye yasimahla. Xa ukugqitywa kwesiphelo sekuqaleni kuncinane xa kuthelekiswa nobude bengcongolo, intwasahlobo ibonakalisa umgca ofanelekileyo kwaye unokuhlalutywa njengentwasahlobo ye-zero.

Uhlalutyo lwemodeli yobuqili ebothukayo ebothukayo ithathela ingqalelo iitoti ezixhaswe yimithombo emibini kwindawo ethile kwinkqubo. Ngokusekwe kumthetho onxantathu, iitoti zinokubonakaliswa ngokwezibalo. Ngokudibanisa ezi nkozo, itotari iyonke enziwayo kwinqaku inokumiselwa. Olu hlalutyo lutyhila ukuba xa i-angle yokujikeleza ingaphantsi kwe-90 degrees, imithombo isebenza kwi-torque kwicandelo elinye ne-engle yojikelezo, ngaloo ndlela kudala ukuqina okungalunganga.

Ukuseka imodeli echanekileyo ye-hinge ye-hinge efudukayo, kubalulekile ukuhlalutya iipropathi zoomatshini be-finge eguqukayo. Olu hlalutyo lujonga izinto ezahlukeneyo ezinje ngefuthe lomkhosi we-radial kunye ne-torsional emsulwa kwi-hinge. Ngokuqonda ezi zinto, ukuqina kwengqondo ye-hinges kunokubalwa. Imodeli yengqondo ye-zero-tinged hinge efihlakeleyo inokuthi emva koko ifumaneke ngokutshintsha isibini esitshatileyo kunye nokulinganisa kwimodeli yothumo olubi. Le modeli yengqondo ilungelelwaniso, ivumela uhlalutyo lokujikeleza kweqonga lokuhamba.

Ukuqinisekisa ukuchaneka kwemodeli yethiyori, uhlalutyo lwezinto ezigqityiweyo usebenzisa isoftware ye-Asneys iqhutywa. Uhlalutyo lubandakanya ukuvelisa kunye nokuhlalutya oko kujikelezayo kwe-angle Iziphumo emva koko zithelekiswa nezibalo zethiyori. Ukulinganisa kwenziwa kwi-chinges kunye neparamitha eyahlukeneyo, kwaye ukuqina kwentsilelo yentwasahlobo kuqinisekisiwe de kufike ukuqina kwe-hinge kuncitshisiwe kwi-zero. Ngokuthelekisa iziphumo zokufakwa kunye nokubala ngethiyori, kuqinisekisiwe ukuba imodeli yethiyori ibonisa ngokuchanekileyo isimilo se-zero-stalfd hinge.

Ngaphaya koko, ukubakho kokusebenzisa igqabi legqabi njengoko i-spings yengozi ye-zero-tingeds eguquguqukayo iyaphononongwa. Imodeli yenqaku eligqityiweyo isekiwe le njongo, kwaye iziphumo zokufakwa zithelekiswa nezo zifunyenweyo zisebenzisa inqaku le-14. Iziphumo zaphinda zaqinisekisa ukuchaneka kunye nokuthembeka kwemodeli yethiyori.

Ukuqukumbela, ukusetyenziswa kokuqina okuqinileyo okungalunganga ukucima ukuqina okuqinisekileyo kwii-hinges eziguquguqukayo kuvumela ukudalwa kweenkqubo ze-hinges eziguqukayo ze-hinge. Ezi nkqubo zinika izibonelelo ezininzi, kubandakanya ukuncitshiswa kweTorque, ukusebenza okuphuculweyo, kunye nokwanda kokusetyenziswa kwamandla amandla. Iindlela ezimbini zebhalansi ezahlukeneyo, ezizezile i-sporings ezimbini kunye ne-spils eyodwa, ziyahlalutywa, kwaye iimeko zazo ezilungeneyo zimiselweyo. Iziphumo zethiyori emva koko ziqinisekisiwe ngohlalutyo lwezinto ezigqityiweyo. Olu phononongo luqinisekisa ukuba indlela yentwasahlobo yentwasahlobo ifanelekile kwiimeko apho amandla e-chinge engachaphazeli ukuqina kwe-hinge, ngelixa imodeli ye-account yentwasahlobo yentwasahlobo inoluhlu olubanzi lwezicelo. Nangona kunjalo, le modeli ye-Axial ye-Axilic ye-Axial ye-Axial ye-Axiction iqulathe ngandlel 'ithile, inyanzelisa ukuqwalaselwa okukhulu ngexesha uyilo lolwakhiwo. Ngokubanzi, uphando malunga ne-zero-gesibles efudumeleyo kwaye izicelo zabo zibaluleke kakhulu ekuqhubeleni phambili icandelo leendlela eziguqukayo.
