Impact resistance test yezvinhu zvinosanganiswa
1. Nzira yekuedza yepasi-speed impact
Kuti vatevedzere maitiro ekukanganisa kwezvinhu pasi pemamiriro chaiwo, vaongorori vakakurudzira nhamba huru yenzira dzekuyedza.Zvinoenderana nemamiriro chaiwo ekukanganisa, kukanganisa kunowanzo kupatsanurwa kuita kumhanyisa-kumhanya uye kuderera-kumhanya kwekuita.
High-speed impact inonziwo ballistic impact.Nekuda kwekuti kukurumidza-kumhanya kwakawana kutariswa kwakakosha munzvimbo dzemuchadenga nemauto, vanhu vakaita tsvakiridzo yakawanda yekuyedza pamusoro pekumhanya-mhanya.High-speed effect inowanzo shandisa diki diki projectile kurova zvinhu nekumhanya kwepamusoro, uye kunyanya inoshandisa pfuti dzemhepo kuvhura projectiles kudzidza maitiro ekumhanya-mhanya kwezvakasanganiswa zvinhu, sezvinoratidzwa pamufananidzo:
Iyo yakaderera-yekumhanyisa bvunzo bvunzo inowanzo tevedzera mabatiro echinhu chikuru-chikuru pamusoro pechinhu chiri pazasi kumhanya, sekudonha netsaona kwechishandiso panguva yekugadzirisa, uye yekudonha-huremu bvunzo mudziyo unowanzo shandiswa kuyedza. simulation.
Mufananidzo 2 Drop sando test device
Mhedzisiro yetsvagiridzo inoratidza kuti chimiro, kunaka uye kumhanya kweiyo projectile ichave nemhedzisiro yakakura pakukundikana kwemaitiro ezvakasanganiswa zvinhu.Semuyenzaniso, vaongorori vakaita tsvakiridzo yakawanda pamusoro pehukama huripo pakati pechimiro chesando yemusoro uye nekukanganisa maitiro ezvakaumbwa zvinhu.Kazhinji kutaura, iyo inopinza musoro wesando inoshandiswa, ndipo panowanikwa nzvimbo yekukanganisa kukuvara kwezvinhu, uye iyo huru yekutadza modhi inoshanduka kubva ku delamination kuenda kumatrix kutadza uye kukuvara.Fiber breaks.
2. Pesvedzero yezvakatipoteredza zvinhu pa low-speed impact performance
Composite zvimiro zvikamu zvinofanirwa kusangana nemamiriro ekunze akaomarara panguva yekushandiswa kwenguva refu, senge tembiricha yepamusoro, tembiricha yakaderera, kupisa kwakanyorova, uye kutenderera kwekupisa.Zvidzidzo zvakaratidza kuti pasi pekuita kwemhoteredzo idzi, ma mechanic properties ye composite zvinhu zvichachinja zvakanyanya.Kupisa bhasikoro kunowanzo kudzikisa kupeta uye kuchinjika kusimba kwesimba rezvakaumbwa, uye kuburitsa huwandu hukuru hwema microcracks mumatrix.
Kunyanya shandisa zvakatipoteredza pretreatment uye kwezvakatipoteredza simulation bvunzo kudzidza kukanganisa kwezvakatipoteredza.Iyo inonzi pretreatment yezvakatipoteredza ndeyekuisa iyo inoumbwa zvinhu kuti iongororwe mune imwe nharaunda kuti igadziriswe pachine nguva, uye wozoisa iyo yakagadziriswa bvunzo kune yakaderera-yekumhanyisa bvunzo pakudziya kwekamuri.Iyo yemamiriro ekunze simulation bvunzo ndeyekuisa iyo inoumbwa zvinhu mukamuri yezvakatipoteredza uchikanganisa.Iyi nzira inoshandiswa kudzidza maitiro ekuita kwezvikamu munzvimbo dzakasiyana dzesevhisi.
3. Mhedzisiro yezvivakwa zvezvinhu pane yakaderera-kumhanya inokanganisa kuita
Fiber inoshandiswa zvakanyanya sekusimbisa mukugadzirwa kwezvinhu zvinosanganiswa.Panguva imwecheteyo, semutakuri mukuru wemutoro, kuita kwefiber kune simba guru pakupikisa kwese kukanganiswa kwezvinhu zvinosanganiswa.Mafibhi anoshandiswa muindasitiri yezvemuchadenga anonyanya kusanganisiracarbon fiber, girazi fiberuye Kevlar fiber.Nekuda kweiyo yakasarudzika brittleness yekabhoni fiber, kupikisa kwekabhoni fiber reinforced resin matrix composite haina simba pane iyo yegirazi fiber uye Kevlar fiber.
Iyo matrix yefiber-yakasimbiswa resin-based composite zvinhu inoita basa rakakosha zvakanyanya muzvinhu zvinoumbwa.Iyo resin matrix haiparadzaniswe kubva kana iri yekufambisa mutoro, kuchengetedza kutaridzika kwefiber kana kuchengetedza kutendeseka kwezvinhu.Mhedzisiro yechidzidzo ichi inoratidza kuti kunyangwe ma mechanics e thermosetting resins ari nani pane aya e thermoplastic resins, iyo muchinjika-yakabatana molecular chimiro che thermosetting resins inoita kuti isanyanya kuomarara, izvo zvinoita kuti vanyanye kutadza kutadza pasi pesimba rekuita.
Iyo interface inoita basa rekufambisa mutoro kune fiber mune inoumbwa zvinhu, saka kuita kweiyo interface kuchakanganisa kuita kwese kweiyo composite zvinhu.Iyo inoumbwa zvinhu ine yakashata interface inobatana pakati pefiber uye matrix inoratidza yakaderera simba uye kuomarara, uye Kunyanya kusimba chisungo kuchaita kuti zvinhu zvipere.
