Kuwedzera pejoinhi kongiri

Kuwedzera pejoinhi kongiri chinhu chinodiwa chezvinonhuwira ichi chakagadzirwa mhando. Vanofanira kuitwa nokuti kana kongiri anoomesa, uye ipapo pamwe tembiricha donhwe uye mwando shanduko iri compression kana nokuwedzera chesamende rakanyorwa. Kana pasina kuwedzera gwanza, siyana deformation magadzirirwo angamuka nokuda chitarisiko yomunyika zvinetso, makatsemuka, nokuda nesimba ipfupi uye mukurumari. Nemhaka kugadzirisa izvi zvinogona kuparadzira pane chimwezve mutoro, kudzivisa deformation pezvakaitwa.

Kuwedzera vagari akaita paaisika zvivako mhando dzose, mazambuko uye menzira. Nokufamba kwenguva, izvozvo zvinogona kuva tsinga neguruva kana mabwe, nekuti waasingazotorerwi kuzadzikisa yayo unodzivirira ushande. Nokuda kwechikonzero ichi zvakakosha kuti nguva nenguva kuchenesa mapfundo. Unogona chivhariso kukura majoini chesamende nokushandiswa chaiwo kwakavharwa nenyama zvinhu kuti kuvadzivirira kusvibiswa, asi hahuzongoparari kukanganisa ehupfumi dzavo. Asati kudira chesamende anowanzoita pave nokuwedzera coefficient Masvomhu hukawanika kuona upamhi uye kureba vazvo, uye kure pakati pavo.

Slicing kuwedzera vadyi, kunofanira kutungamirirwa mamwe mazano:

- berekai nenguva nzira. Pachisarudzo yemazuva ano dzakarurama anganzi nokuveza yavo yakachena kongiri pakarepo pashure pemvura iri rinobwinya. Kana basa rinoitwa zvikuru gare gare, kuti, apo zvinhu anoomesa, ipapo kumicheto zvinogona kukonzera makatsemuka izvo kanganisa mashoko spatial zvechadenga zvinhu. Saka Zvinokurudzirwa kuti kucheka sutures pashure pemaawa 12 pashure kudira kana rimwe zuva, kana basa rakanga raitwa panguva tembiricha ipfupi.

- Temperature musono muchivako anofanira kuva namaapuro kudzika, oscillating mukati mumwe pavatatu kota zvachose ukobvu yacho screed yapihwa.

- Cutting yaifanira pamwe pakuomerera kuchengeta penguva.

- Sliced pajira riya haafaniri zvine dzakawanda vazvo vave kunyanya cracking walnut kumbowanikwa yomukati makona.

- Temperature-shrinkage majoini haafaniri vayambuka T-chimiro, sezvo yakadaro remubatanidzwa kazhinji ave kukonzera makatsemuka intersecting kunoguma musono.

- On the afoot harifaniri kuva migove kuva mativi makona nokuda deformation kazhinji kutanga kumigumo chakasimba pamakona. Kana usingagoni kudzivisa munhu mativi chimiro, chirungamutauro kunofanira kuitwa equilateral.

Kuwedzera vagari akagadzirirwa kudzivirira masvingo kubva pakaita makatsemuka panguva tembiricha deformations. Zvinokwanisika kutonga kubva anotevera data, akadai guru deformation: chivakwa ibwe kuti pa 20 madhigirii tembiricha pamwero ane kureba 20 metres, tembiricha pa -20 madhigirii pamwero anova 10 mm pfupi. Musono anoshanda ari rurimi ane udzamu kunofanira vanenge 5-10 millimeters.
