Iyo Wavelet Kuongorora Kwekuwedzeredza Mune Mahara-Fomu Inotarisa CNC Machining

Huwandu hukuru hwemidziyo yakadai seCCC maturusi emuchina uye nzvimbo dzekushandisa zvinoshandiswa mukugadzira chakuvhuvhu. Iyo yekugadzira kutenderera yakareba. Vashandisi vanowanzo neta. Kamwe kukundikana kukaitika, zvinowanzotora masekonzi mashoma kubva pakuona kwevanhu kutora matanho anoenderana, izvo zvinogona kutungamira kune zvigadzirwa zvemidziyo, Zvichikonzera kurasikirwa kukuru kwehupfumi. Kune akawanda epamba uye ekunze matsva ekutsvagisa nezve chishandiso chakatsemuka uye machining kukanganisa kuongororwa muzvizhinji zvikamu zvekugadzirisa. Mazhinji acho akanangana neacoustic emission, kutema simba kana kutarisa kudedera, nezvimwe, uye kufambira mberi kukuru kwakaitwa. Nekudaro, iko kugadzirisa kwakaomarara. Mould uye zvimwe zvekushandira zvine mahara-fomu pevhu maficha achiri kushaya anoshanda ekuongorora tekinoroji. Icho chikonzero ndechekuti iyo yekucheka-yakatemwa chiratidzo chinonetsa kuziva. Imwe ndeye kupa nzira dzinoshanda dzeyechokwadi-nguva yekutarisa. Ichi chinyorwa chinoshandisa ikozvino chiratidzo chekugadzirisa maturusi-wavelet kuongorora. "Yakatarisisa" kuongorora kunoitwa panguva dzakasiyana nguva uye mafirita mabhendi echiratidzo chepakutanga kunyatsoburitsa chiratidzo chakatemwa kubva kunguva-frequency nzvimbo. 1 Wavelet ongororo pfungwa Wavelet ongororo ndiko kusimudzira kweina Fourier ongororo. Iyo inoshandisa Xu Shuxin et al. Yemahara-fomu pamusoro pehuwandu hwehuwandu kudzora Wavelet kuongororwa kwekuwedzeredza-kugadzirisa mukugadzirisa Iyo yakasununguka wavelet hwaro basa kb (t) inoshandiswa seyakakosha shanduko basa. Kune akasiyana mafrifits, iyo hwindo yenguva inochinjika otomatiki kana iyo yakakwira-frequency maitiro akaongororwa uye akaonekwa zvichienderana nekuwedzera uye kudzvanywa kweiyero paramende a (a yakaderedzwa) Kana uchiongorora uye uchiona yakaderera-frequency maitiro (kuwedzera), iyo hwindo rinowedzeredzwa roga, uye hwindo hwakawanda hwakatetepa, izvo zvinoona shanduko yeiyo nguva-frequency hwindo renguva dzakasiyana. Basa rehwaro rinogona kuchinjwa. Slide uchitevedza iyo nguva axis, kuti iwe ugone kuongorora chero ruzivo rwechiratidzo chero nguva.

2 Wavelet yekuongorora musimboti weakawandisa chiratidzo mune yemahara-fomu fomu yekugadzirisa. MuCNC machine, mharadzano yechishandiso inopera kumeso uye nepamusoro peiyo workpiece inonzi inodarika-kutema. Izvo ndezvekucheka zvisina kujairika. Kana iyo yemahara-fomu pamusoro peiyo workpiece yapfuura, iyo yekucheka simba inoerekana yachinja, zvichikonzera Iko kucheka simba shanduko, uye mota yazvino inotyaira chishandiso ichachinjawo zvinoenderana. Naizvozvo, kuongorora shanduko yemota yazvino neyekucheka simba kunogona kunangana nenzira yechishandiso uye kubvisa chiratidzo chezvino kubva kumotokari yekumonera. Nzira yakapusa kuita ndeye / ine yakateedzana kuramba. U kutendeuka, kuburitsa muchimiro chemagetsi, asi kuwedzerwa kwekudzivirira kunochinja hunhu hwemota yemota pachayo, iyo inoderedza kunyatso kuyerwa. Uye zvakare, zvimwe zviridzwa zvakabatana kumativi maviri eanopokana zvinofanirwa kushandurwa zvakaenzana kuti zvimise kugona kwayo, izvo pasina mubvunzo zvinowedzera kuomarara kwesystem system. Nekuda kweizvi, bepa iri rinoshandisa rinosimudza muyero Horo yazvino sensor. Iyo sensor pachayo yakabatana neDC magetsi magetsi. Magnetic field inogadzirwa mukati meiyo Horo element. Kana yazvino yekuisa terminal yemotokari yakabatana neiyo sensor, yazvino inogadzirwa pane yayo inobuda terminal. Iyo inogadzira yakaenzana magineti munda mukati meiyo Horo element. Kana mota yazvino ikachinja, iyo yakaenzana magineti inobatika. Kuti uwane chiyero chitsva, zvinobuda izvozvi zvinofanirwa kuchinjwa zvinoenderana. Nekuti iyo Horo element ine hukama hwakanaka hwemitsara pakati pekuisa nekubuda, iko kuchinjika kwechiratidzo chayo chekuburitsa kunogona kuratidza zvisina kunangana shanduko yemota yazvino. Gadza chiratidzo chekuburitsa Is f (t), koenderera mberi wavelet shanduko ye f (t) inogona kutsanangurwa seyakawanda-resolution yekufungidzira kwechigadzirwa chemukati che f (t) uye,) (, inoenderana chikero basa 1, saka hwaro basa reV / nzvimbo inofanirwa zvakare kuwanikwa Mune yeV / + i nzvimbo, canonical orthogonal hwaro hweV / + i nzvimbo inogona kushandiswa kuratidza fungidziro ye1 ne2'zvinoteedzana mune orthogonal fungidziro yeV / + ini uye V /. Zvinoenderana nerevo yekufungidzira, iyo resolution Iyo yakajeka chiratidzo ye2 inofanirwa kunge iri orthogonal fungidziro yechiratidzo chekutanga pane orthogonal inowedzerana nzvimbo yeV / nezve V + 1. Rega iyi orthogonal yekuwedzera nzvimbo ive W /, ndiko kuti, hwaro basa reW / nzvimbo 2 / (x -2 / n) inofanirwa zvakare kuve iri muV / + i nzvimbo, saka canonical orthogonal base fomula (5) mu iyo V + 1 nzvimbo inogona zvakare kushandiswa kuratidza chiratidzo / (t) GV + 1, ipapo fomura iri pamusoro inoratidza kuti f (Iyo yakasarudzika yekufungidzira Af of t) inogona kuwanikwa kubva padanho repamusoro-padanho rekufungidzira Ad + i / pfuura firita. Iyo yakajeka chiratidzo D / f ye f (t) inogona zvakare kuwanikwa kubva padanho repamusoro-discrete yekufungidzira Ad + i / pasa imwe firita. Iyo firita h (n) g (n) inotsanangurwa nechomukati chigadzirwa chechiyero chinoshanda h (t) uye wavelet basa ⑴.

Yezve dijitari chiratidzo chakatemwa nekombuta, iyo dyadic siginari idiki inopfuura. Chishandiswa 2 zvishandiso zvinowanzoitika. Kuitira kurerutsa iyo bvunzo maitiro uchiona nezve hunhu hunokosha hwekuwedzeredza, ichi chinyorwa chakaitisa iyo overcut simulation bvunzo sezvakaratidzwa. Iyo sampling frequency ndeye 1kHz. / min, iyo yepamusoro yekudzika ndeye Hg = 3.1mm, iyo yekushandira zvinhu ndeye A8 simbi, uye icho chinhu chekushandisa chakakwirira-kumhanya simbi. Iyo chiratidzo chakayerwa chinoratidzwa muS muS mune-yakatemwa-chiratidzo chiratidzo uye wavelet kuora. Izvo zvinogona kuoneka kuti iyo nguva-domain chiratidzo chinonyanya kuomarara, uye hapana chiri pachena pamusoro-cheka chimiro. Semuenzaniso, kana ichicherechedzwa mune frequency duraini, chaiyo-nguva yekutarisa haigone kuwanikwa nekuda kwekushayikwa kwekumisikidza mudura yenguva. chinangwa che. Naizvozvo, chiratidzo chepakutanga chakayerwa chinoiswa mukuora kwemazuru, uye mhedzisiro yeshanduko yakanyorwa mumhedzisiro yeshanduko. Inogona kuoneka kubva pamhedzisiro yeshanduko yekuti kana kudarika kwanyanyisa kukaitika, kuratidzwa pane diki chiyero (yakakwira frequency) hakuonekwe, asi chimiro chepamusoro chinopenya pachiyero chechina. Zvinotaridza kuti mukutarisa chaiko, chikumbaridzo chinogona kumisikidzwa pachiyero ichi kuti chione mamiriro ekucheka, uye nzvimbo yaro yekucheka yakanyatso kuwanikwa mune ese nguva-frequency mafambiro mune wavelet shandura girafu, iri nyore yekutarisa-chaiyo-nguva . 3.2 Muchinjikwa-cheka bvunzo Mamiriro maviri ebvunzo: yekugaya cutter dhayamita iri 10mm, kucheka kudzika = 0.5mm, chokurukisa kumhanya n = 500r / min, feed kumhanya v = 150mm / min, overcut udzamu Q1mm, workpiece zvinhu ndeyeMvura, chishandiso zvinhu simbi inomhanya-mhanya Chiratidzo chakayerwa uye kuora kwayo kwewuru kunogona kuonekwa kubva pamufananidzo. Inogona kuonekwa kubva kumufananidzo kuti iyo yekucheka-nzvimbo haina kuoneka mune yakakwira frequency renji. Zvakare pachiyero chechina, iyo yekucheka-pamusoro inoonekwa zvakajeka. 4 Mhedziso Wavelet inoshandura kuita yenguva-frequency chiratidzo ichi Inopa hwaro hwemasvomhu, inotora nzira yekuongorora mawindo, inogona kuongorora chiratidzo kubva kunguva yedomain uye frequency domain panguva imwe chete, uye kuita chaiyo nguva-frequency kumisikidzwa kwemapoinzi. yekufarira. MuNC kugadzirwa kweiyo yemahara-fomu pamusoro peiyo workpiece, kutapudza ndiyo yakajairika fomu yekutadza. Iyo yekupinda poindi ine rakapfuma frequency ruzivo, asi zvinonetsa kuwana rakakodzera ruzivo nezve pamusoro pekuwedzeredza chete kubva panguva yenguva yekutarisa. Kuongorora kweWavelet kunogona kucherechedza chiratidzo panguva dzakasiyana uye zvikamu, uye inogona kunyatso bvisa ruzivo rwakasiyana nezve iyo frequency mutation poindi. Inotaridza kuti panguva, nzvimbo inoshandisa "yakatarisana" kuongorora kuti icherechedze ruzivo rwekuwedzeredza. Kunyangwe iwo maratidziro asiri pachena mune mamwe ma frequency bhendi, mune mamwe ma frequency mabhendi, wavelet coefficient kukosha iri pachena yakatanhamara, iyo inogona kunyatso kuona mamiriro ekucheka kwechombo munguva chaiye.
