O e malamalama i le Togafitiga Aafiaga o le Ultrasonic ?

Ole tele o aafiaga ole masini eletise (HFMI), e taʻua foi ole Ultrasonic Impact Togafitiga (UIT), o se maualuga-taimi masani togafitiga aafiaga togafitiga fuafuaina e faaleleia ai le lelava tetee o ueloina fausaga. I le tele o alamanuia talosaga o lenei gaioiga e taua foi o le ultrasonic peening (UP ).

O se malulu masini togafitiga e aofia ai le taina o le toe tamatamaʻivae ma se nila e fausia ai se faʻateleina o lona faataamilosaga ma faʻalauiloa toega compressive popolega.

I se tulaga lautele, o le faʻaaogaina UP faiga faʻaalia e mafai ona faʻaaogaina mo togafitiga o toe soʻoga vae poʻo uelo ma lapoʻa luga vaega pe a tatau ai.

Tagata gaioi gaioi

O le UP masini e faʻavae i luga o le iloa mai le 40's o le seneturi talu ai faʻapitoa faʻafitauli o le faʻaaogaina o galulue ulu ma saoloto feaveaʻi tagata faʻatau mo hammer peening. I lena taimi ma mulimuli ane, a tele o eseese mea faigaluega faʻavae i luga o le faʻaaogaina saoloto feaveai strikers na atiaʻe mo aʻafiaga togafitiga o mea ma elemeni elemeni e ala i le faʻaaogaina o masini pneumatic ma ultrasonic. O le sili atu le aoga aʻafiaga togafitiga e maua pe a le o tagata lavea e le fesoʻotaʻi i le pito o le actuator ae mafai ona feoaʻi saoloto i le va o le actuator ma le togafitia mea. O mea faigaluega mo aʻafiaga togafitiga o mea ma elemeni uʻamea ma le saoloto feaveai strikers o loʻo faʻapipiʻi i totonu o se o loʻo faʻaalia. I le tulaga o le taua o le vavalalata elemeni-striker (s) o le malosiaga na o 30 - 50 N e manaʻomia mo togafitiga o mea.

Vaʻaiga vaʻaia e ala i mea faigaluega ma saoloto feaveai strikers mo luga aafiaga togafitiga.

O loʻo faʻaalia ai se seti masani o faigofie ona suia ulu galue ma tagata faʻatau fua mo faʻaoga eseese o le UP.

Se seti o fesuiaʻi galulue ulu mo UP

I le taimi o le togafitiga o le ultrasonic, oscillates le tagata fasi i le tamaʻi va i le va o le iʻuga o le ultrasonic transducer ma le togafiti faʻataʻitaʻia, aʻafia ai le vaega na togafitia. Lenei ituaiga o maualuga fegasoloaʻiga gaioiga / aʻafiaga i le tuʻufaʻatasia ma maualuga oscillations masani faʻaosoina i le togafitia mea e masani ona taua o le ultrasonic aʻafiaga.

Tekonolosi ma Masini mo Ultrasonic Peening

O le ultrasonic transducer oscillates i se maualuga taimi, ma le 20-30 kHz e masani ai. O le ultrasonic transducer atonu e faʻavae i luga ole piezoelectric poʻo le magnetostrictive tekinolosi. Poʻo le a lava tekinolosi e faʻaaogaina, o le pito iuga o le transducer o le a oscillate, e masani lava ma le maualuga o le 20 - 40 mm. I taimi o oscillations, o le transducer tip o le a aʻafia ai le tagata faʻataʻitaʻi (s) i vaega eseese o le oscillation cycle. O le tagata taia, o le a, aʻafia, afaina ai luga togafitiga. O le iʻuga e mafua ai i le palasitika faʻasologa o laualuga vaega o mea. O nei aʻafiaga, toe faitau selau i le afe ma afe o taimi i le sekone, faatasi ai ma oscillation maualuga taimi faʻaosoina i le togafitia mea na mafua ai le tele o aoga aoga o le UP.

Ole UP ose auala lelei lea mo le faʻamamaina o faʻalavelave faʻafitauli ogaoga ma le faʻaaogaina o faʻafitauli aoga o loʻo taofiofia ile pito i luga ole vaega ma vaega ole uʻamea.

I le faʻaletonu lelava, o le aoga aafiaga e maua faʻapitoa e ala i le faʻalauiloaina o le compressive toegafesolo mamafa i luga vaega o uʻamea ma alloys, faʻaititia o le mamafa faʻatosinaina i vaega toe uʻamea toe ma le faʻaleleia o le masini meatotino o le laualuga vaega o mea.

Talosaga Alamanuia o UP

E mafai ona faʻaoga lelei le UP mo le faʻamalieina o le ola i le taimi o le gaosiga, toe faʻaleleia ma le toe faʻaleleia o vaega uʻamea ma vaega. O le UP tekinolosi ma masini na faʻaoga lelei i galuega eseese tau alamanuia mo le toe faʻaleleia ma le toe faʻaleleia o vaega ma elemeni elemeni. O vaega / pisinisi na faʻaoga lelei ai le UP e aofia ai: Alalaupapa ma Alalaupapa Alalaupapa, Fausiaina o Meafaigaluega, Vaʻa Vaʻa, Mining, Taʻavale ma Vaʻaia.
