Acoustic ekushayweni piping

представляет собой возникновение и распространение упругих колебаний в процессе деформации исследуемой конструкции. ekushayweni Acoustic kuyinto ukuvela piping kanye ukusabalala kunyakaza nokunwebeka ngesikhathi design cwaningo ukusonteka. Quantitatively, ke izenzo kube inkomba yokuthi ubuqotho impahla ngaphansi komthwalo obuhlukahlukene. может применяться для установления дефектов на начальном этапе разрушения конструкции. Indlela ukulawula ekushayweni acoustic ingasetshenziswa ukunquma yokulimala esigabeni sokuqala ukwehluleka kwesakhiwo. Indlela eyinhloko uphethwe iqoqo yokwenziwa kolwazi nokucutshungulwa kwalo okwalandela.

izici Jikelele

используется для обнаружения и установления координат, мониторинга источников деформации на поверхностях либо в объеме стенок, сварных соединений и элементов конструкций. ekushayweni Acoustic isetshenziswa ukuthola nokuxhumanisa imithombo ukuqapha ukusonteka ezindaweni noma izindonga isikrini, amalunga ashiselwe kanye timphawu tesakhiwo. Sifo wenziwa kuphela uma isimo ukucindezeleka. It omula umsebenzi imithombo into oscillation. возникает при воздействии давлением, силой, температурным полем и так далее. ekushayweni Acoustic kwenzeka lapho zihlatshwa ingcindezi, force, izinga lokushisa ensimini nokunye. Ukukhetha umthwalo ethile kunqunywa tesakhiwo ukuthi isetshenziswa izimo ngaphansi kwazo, isivivinyo ngokucacile.

acoustic ekushayweni indlela

Ukuze ubone ukuthi isakhiwo nokwethenjelwa Inkomba ihlola imingcele yayo kanye nezimpahla okuyiwona akumele i- ubuqotho kanye usability kanye nokusebenza. izindlela ezivamile (ultrasonic, eddy zamanje, emisebeni nezinye ethandwa practice) embule nonuniformity weJiyomethri bemisebe we amandla athile ku isakhiwo into. предполагает иной подход. ekushayweni Acoustic kusikisela indlela ehlukile. Ngokuyinhloko indaba umthombo uqobo uba yinto sangaphandle njengoba yokwenziwa wokuhlola indlela, ayisebenzi njengoba kukhonjisiwe ngenhla. позволяет обнаружить не статические неоднородности, а перемещение дефекта. Ngaphezu kwalokho, kwekhabhoni acoustic kungathola hhayi inhomogeneity static futhi isici ukunyakaza. Ngakho, ingasetshenziswa ukukhomba ekuthuthukiseni ngakhoke umonakalo esiyingozi kakhulu. Le ndlela ivumela ukuba ngokushesha ukuthola ukuqhekeka okuncane wakhula, liquid noma igesi ukuvuza, waphuka nezinye izinqubo okubangela kuqala futhi Lokusakaza oscillations.

umehluko wemisindo nemiqondo yamagama

I-theory kanye nama-practical imigomo, noma isiphi isici uyakwazi ukukhiqiza isignali lalo. . Kungaba sinqobe amabanga kunalokho enkulu (a emashumini ambalwa amamitha), ngenkathi awayiboni le acoustic ekushayweni inzwa. Ngaphezu kwalokho, ukucekelwa phansi bungabonakala hhayi kuphela elawulwa kude. Ukuphazamiseka kwekhono amiswa kubalwa umehluko kanye nesikhathi amagagasi sokufika kuya izinzwa ngokuhlanganisa sise amasayithi ahlukene. Ukukhula imifantu, delaminations, inclusions ukwa, nemihuzuko, ukugqwala, ukuvuza liquid / igesi - izibonelo izinqubo ezikhiqiza kunyakaza ukuthi sikwazi ukubona futhi ukuphenya ngempumelelo.

Izici

Izinzuzo main phezu indlela evamile zezindlela zokuhlola ze-non-okulimazayo:

1. Integrality. , неподвижно установленный на поверхности конструкции, можно проверить ее всю целиком. Siqukethe eqinisweni lokuthi ngokusebenzisa i-transducer olulodwa ekushayweni acoustic fixedly ogibele kobuso isakhiwo, ungabheka konke ngokuphelele. Le mpahla kubalulekile ikakhulukazi kulolu cwaningo ezindaweni ezinzima noma ongangeneki.
2. Asikho isidingo azokuqhubela ukulungiselela ngokungashwampuluzi we ebusweni into. Kule kusobala ukuthi inqubo control uqobo, kanye nemiphumela ngeke kuxhomeke esimweni isakhiwo kanye nekhwalithi ukucubungula. Uma kukhona enamathela ukwahlukanisa, khona-ke kumelwe kususwe kuphela idivayisi izindawo ukufakwa nokuphepha.
3. Ukukhomba kanye nokubhaliswa kuphela ekuthuthukiseni umonakalo. Lokhu kuvumela Ukwahlukaniswa ukukhubazeka hhayi isayizi yabo noma amanye amapharamitha engaqondile (isikhundla, ukuma, ukuma), kanye nezinga ingozi (idigri ithonya ekuqineni esingaphakathi kwento).
4. ukusebenza okuphezulu. Kuyinto izikhathi eziningi ngaphezu kwezihlalo izibalo esihambisanayo ezivamile (radiographic, ultrasonic, kazibuthe, eddy zamanje, nokunye.) Izindlela control.
5. Remote. Ihlola amandla into engenziwa ngesikhathi eside ibanga opharetha. Lesi sici ikuvumela ukuthi usebenzise indlela ekweluseni isimo, esiyingozi kakhulu, izakhiwo ezinkulu enwetshiwe ngaphandle decommissioning nokusongelwa abasebenzi.

Enye inzuzo ukuthi ikhono ukuqapha izinqubo ezihlukahlukene ubunjiniyela kanye nokuhlola isakhiwo e isimo esikhathini samanje. Lokhu kusiza ekunqandeni ekulimaleni okwenzeke ngephutha into. Kufanele kuqashelwe ukuthi le ndlela ekushayweni acoustic ngokufanele kuhlanganiswe imingcele izinga kanye nezindleko.

ngaphezu kwalokho

Control usebenzisa isidoda acoustic inikeza oluningi ulwazi kwenza kube eziphansi operably alawule futhi wandise umjikelezo yokusebenza ukufuna ukufaka ezimbonini. Imiphumela ukuhlolwa elisetshenziswa isibikezelo ekubhujisweni eziphuthumayo. Le ndlela ukulawula ingasetshenziswa ukufunda ezihlukahlukene izakhiwo ezibonakalayo, izakhiwo, izinto. Namuhla ngaphandle akunakwenzeka ukwakha kanye ukusebenza onokwethenjelwa iqoqo izindawo ezibucayi embonini.

nebubi

Have acoustic ekushayweni indlela, nezinkinga ezithile. The main nobunzima lokususa wenza kulungiswa ngenkathi kokuhlola izinkomba wathola. Lokhu kusimo kakhulu kukhawulela ukusetshenziswa kabanzi indlela practice. Ukuba yinkimbinkimbi ubangelwa yokuthi ngesikhathi wave ekushayweni acoustic izinqubo esikhulu okuthiwa izinkomba engamanga zande kubonakala amagagasi umsindo kusukela imishini, ukukhokhiswa into kanye imvelo. Ukusetshenziswa izinhlelo ukuvikelwa nokuhlunga ahlukahlukene ivumela kuphela ingxenye banciphise umthelela. Ngaphezu kwalokhu ethile ubhekwa imishini ehlukile esetshenziselwa ukulawula. Esikhathini umkhakha it is hhayi kukhiqizwa ngamanani amakhulu. Iphinde ivumele masibonise ngendlela ukuqhubekisela phambili emkhakheni yokusetshenziswa zokuhlola.

Fields of kwesicelo

Njengoba kushiwo ngenhla, okwamanje indlela ekushayweni acoustic kuthiwa amabhizinisi ezahlukene wahlanganyela kwemikhakha ehlukene kwezomnotho. Khona-ke abakhululiwe eziyinhloko:

1. Chemical nophethiloli ongahluziwe izimboni.
2. Metallurgy futhi ukukhiqizwa ugingqe.
3. Thermal futhi ngamandla enuzi isizukulwane.
4. Izitimela.
5. Aerospace eziyinkimbinkimbi.

Indlela kabanzi amabhizinisi, ukusebenza izinsimbi, ibhuloho izakhiwo, ukhonkolo kanye kwagcizelela izakhiwo zikakhonkolo.

isiphetho

Acoustic ekushayweni indlela kubhekwa namuhla enye yezindlela eziphumelela kakhulu ukwenza ukuhlolwa non-elimazayo nokuhlola izinto izakhiwo. Kusekelwe ukuthola amagagasi nokunwebeka elakhiwe uma ukusonteka ngokuzumayo isakhiwo ngaphansi komthwalo. iyehla iyenyuka Okuphambili bachezuke lwaluvelaphi futhi ithunyelwe ngokuqondile e-Transmitter lapho siguqulelwa yezinzwa. amadivaysi Special wabenza eba yiqhwa. Ngemva kwalokho, kukhona ukubonisa ulwazi kusetshenzwe. Ngezinye kwesisekelo salo wenziwa ukuhlolwa okwalandela lwesakhiwo futhi ukuziphatha izinto.
