Isakhelo seNet, iklasi yoLwakhiwo lwabasetyhini

Iiyunithi ezisisiseko zesakhelo segridi ziyi-cone engunxantathu, umzimba ongunxantathu, ityhubhu, i-quadrangle enqunqwe njalo njalo. Ezi zinto zisisiseko zinokudityaniswa zenze i-tripod, i-quadrilateral, i-hexagonal, isetyhula, okanye nayiphi na enye indlela yesimo seplanethi. izibonelelo zamandla esithuba, ubunzima bokukhanya, ukuqina okukhulu, ukusebenza kakuhle kwenyikima, njl.inokusetyenziswa njengophahla lweyithambiso, iholo yemiboniso, iholo yemiboniso, iholo lokulinda, ibala lokuma kwebala, indawo yokuma kwinqwelo moya, indlela-ezimbini indawo yokusebenzela kunye nezinye izakhiwo.

Ukuhlelwa kwigridi:

Iklasi yokuqala yenziwe ngenkqubo yeenqwelomoya, ezibandakanya iifom ezine, ezithi, i-grid enee-directional orthogonally straight grid grid, i-direction-orthogonally ethambekele ekubekeni iigridi, i-direction-oblique ye-oblique yokubeka i-grid kunye ne-three-direction.

Uhlobo lwesibini luqulathe iiyunithi zephiramidi enamacala amane. Kukho iindlela ezintlanu: iigridi zecatrilateral eziqinisekileyo, iigridi zecatrilateral, iigridi zekota yesango lokujonga, igridi yokujonga kwibhodi enamacala amane kunye nenkwenkwezi yegridi yangaphakathi.

Uhlobo lwesithathu luqulathe iiyunithi ezingunxantathu zepiramidi. Zintathu iintlobo zeminatha engunxantathu yeepiramidi, iminatha yeetricone eyongezelelweyo kunye nobusi beetriki zenyosi.Ngokuya ngohlobo lobuso beqokobhe, ulwakhiwo lweqokobhe lungahlulahlulwa lube liqokobhe leesilinda, igobolondo elingqukuva kunye neqokobhe leparabri yehyperbolic. Kukho iigridi zentsimbi, igridi yekhonkrithi eqinisiweyo kunye nentsimbi kunye negridi edityanisiweyo yekhonkrithi, apho kusetyenziswa khona iigridi zentsimbi.

Uhlalutyo lwamandla angaphakathi kwigridi:

Ulwakhiwo lwegridi yinkqubo ephezulu yesimo esingagungqiyo kwinkqubo yohlalutyo lwetafile yohlobo lweplate, kuthathwa ngokubanzi ukuba amalungu adibeneyo, kwaye umthwalo wangaphandle wenziwa kumalungu ngokuhambelana nomgaqo olinganayo, onokuthi kubalwa ngokwendlela yendawo yokuhambisa indawo, eyile ndlela yokugqibezela yenkqubo yeentonga ezixhonyiweyo.Iindlela zokubala ezilula, ezinje ngenkqubo yohlalutyo lwenkqubo yokuphambuka kunye nendlela yeplate, inokusetyenziselwa ukubala imikhosi yangaphakathi kunye nokufuduswa. Iqokobhe le-single-layer truss ngokubanzi kucingelwa ukuba yindibaniselwano eqinileyo, ekufuneka ibalwe ngokungqinelana nendlela yento ecekeceke yenkqubo yokudibanisa engqingqwa.Igridi yegobolondo ephindwe kabini ingabalwa ngendlela yento ephelileyo yenkqubo yentonga exhomekeke kuyo. -Shell indlela inokusetyenziselwa ukwenza ukubalwa kobume obungqongqo kunye nolwakhiwo oluphindwe kabini lweqokobhe.

Uyilo loyilo lwegridi:

Icandelo lomnqamlezo wesakhiwo somthi kufuneka limiselwe ngokokubalwa kwamandla kunye nozinzo Ukuze kuncitshiswe ubude obubaliweyo be-bar yoxinzelelo kunye nokwandisa uzinzo, amanyathelo afana nokongeza ibha yokuhlulahlula kunye nebar yokuxhasa inokwamkelwa. Igridi yohlobo lweplate kunye negridi yegobolondo eyenziwe ngentsimbi ikakhulu ibandakanya iifom ezintathu: ukudityaniswa kweplate, ukudityaniswa kwebhola kunye nebholiti yebhola. Intonga kunye neplani edityanisiweyo zidityaniswe nge-welding okanye i-high-strength bolts. Amalungu ebhola yebhola kunye namalungu ebhola e-bolt afanelekile kulwakhiwo lombhobho wentsimbi. Amalungu e-single-layer shell shell grid kufuneka akwazi ukumelana nokugoba. imikhosi yangaphakathi. Ngokubanzi, ukusetyenziswa kwesinyithi samalungu kudibanisa i-15 ~ 20% yentsimbi esetyenziswe kulwakhiwo lwesakhiwo segridi ....
