Kuiswa kweiyo ultrasonic vibration inoshandura zvakanyanya iyo geometric chimiro cheinoguma pamusoro. Muonde. 3-a, b ratidza mifananidzo yemakwiriro esimbi akaomeswa-zvidimbu zvinorapwa neINJINEERING YEMAHARA DZIMWE Jelgava, 25.-27.05.2016.
220 echinyakare (zvidimbu zvekurudyi) uye ultrasonic kutendeuka (zvidimbu zvekuruboshwe) pakumhanya kwekucheka kwe10 m · min-1 (a)
uye 60 m · min-1 (b), uye 0.05 mm · rev-1. Musiyano wakakura muhunhu hwepadenga uri pachena.
Iyo yepamusoro inowanikwa neiyo ultrasonic kutendeuka ine yakasarudzika yenguva dzose chimiro. Izvi zvinosimbiswa neiyo yepamusoro profilogram (Fig. 3-c), irwo kurudyi chikamu chakawanikwa nekutsika kutendeuka nechikamu chekuruboshwe - nekutenderera kweiyo ultrasonic. Recurrent trough ine nhanho dzefidi ye0.05 mm, iyo inogona kucherechedzwa mumativi ese ari maviri eprofilogram, inomiririra mucherechedzo wepamusoro wecheki. Mune Fig. 3-ba chidimbu cheiyo ultrasonic kutendeuka inoratidzira nguva nenguva kutendeuka mapepa nekuda kweiyo periodic (ine frequency ye20 kHz) kudyidzana pakati pechishandiso pamwe nebasa-chidimbu. Zvakare, kudhindwa kwakadaro, kana kwakawedzerwa, kunoonekwa pamusoro (Mufananidzo 3-a), asi pano haaonekwe sezvo nhanho yavo iri shoma zvakanyanya nekuda kwekumhanya kwakaderera kumhanya.

Chimiro. 3. Simbi yakaoma: a, b - nzvimbo dzakarapwa; c - muenzaniso weprofilogram

 

Misiyano yakadaro mumhedzisiro yekucheka inokonzerwa neshanduko yehutongi hwekutema. Mukucheka kwetsika pasi pekuenderera kwekudyidzana pakati pechishandiso uye nebasa-chidimbu, iyo nzvimbo yekushomeka kwepurasitiki iri padyo nemakona ekucheka uye inopararira nekumhanyisa kumhanya. Iyi zone izere nemakro-madiki, akagoverwa zvisina kurongeka. Nekuda kweizvozvo, iyo yepamusoro ine yakajairika kugoverwa kweiyo microroughness. Ultrasonic yekucheka ndiyo mhedzisiro ye periodic micro kukanganisa, kubudirira nehurefu hwakawanda. Nekuda kwekudzokororwazve kwehuwandu uye iyo pfupi nguva yemapurasitiki epurasitiki deformation zone inoiswa mune diki nharaunda yekumusoro kwechombo, uye nzvimbo yacho haina kuzadzwa nema microcracks asina nguva yekukura. Naizvozvo, nzira yeanocheka pamusoro pechinhu chebasa-chidimbu inoratidzira ichinyora chinyorwa chechimiro chayo, sezvakaratidzwa mumufananidzo 3-b.
