huitwa mtetemo wa kujisababisha au mtetemo usio imara \u2014 ni aina hatari sana ya mwendo ambapo harakati za mfumo huzalisha nguvu zenyewe zinazoiendeleza au kuiongeza harakati hiyo. Matokeo yake ni mzunguko uliofungwa wa maoni: mtetemo hutengeneza nguvu yake ya kuendesha, hivyo ukubwa wake unaweza kukua, wakati mwingine hadi kiwango cha maafa, bila ongezeko lolote la msisimko wowote wa nje. Ni utaratibu nyuma ya baadhi ya kutokuwa imara kunakoogopwa zaidi katika <a href=\"https:\/\/vibromera.eu\/sw\/glossary\/rotor-dynamics\/\">rotor dynamics<\/a>, na kutambua hilo haraka ni ujuzi wa msingi wa utambuzi.<\/p>\n<p>Hii ni tofauti kabisa na <a href=\"https:\/\/vibromera.eu\/sw\/glossary\/forced-vibration\/\">forced vibration<\/a> such as <a href=\"https:\/\/vibromera.eu\/sw\/glossary\/unbalance\/\">unbalance<\/a> or <a href=\"https:\/\/vibromera.eu\/sw\/glossary\/misalignment\/\">misalignment<\/a>, ambapo mtetemo ni mwitikio wa moja kwa moja, sawiano na ingizo maalum la mara kwa mara kwa mzunguko wa kulazimisha unaojulikana. Mara mbili ya kutofautiana kwa uzani na utaona mwitikio mara mbili; ondoa kulazimisha na mtetemo utakoma. Katika mfumo wa kujichochea hakuna saa ya nje kama hiyo \u2014 mwendo hujilisha mwenyewe, na nishati inayouendesha inatokana na chanzo imara kama vile mzunguko, mtiririko wa maji au mchakato wa kukata.<\/p>\n<h2>1. Utaratibu wa Mzunguko wa Maoni<\/h2>\n<p>Utaratibu wa mtetemo wa kujichochea unaweza kuainishwa kama mfululizo:<\/p>\n<ol>\n<li>Mfumo \u2014 kama vile rotor inayozunguka katika beari yake \u2014 uko katika mwendo thabiti.<\/li>\n<li>Usumbufu mdogo, wa nasibu unazalisha mkengeuko kidogo au mabadiliko ya kasi.<\/li>\n<li>Mabadiliko hayo ya mwendo hubadilisha nguvu zinazofanya kazi kwenye mfumo \u2014 kwa mfano shinikizo la maji ndani ya <a href=\"https:\/\/vibromera.eu\/sw\/glossary\/journal-bearing\/\">miinuko ya gazeti<\/a> au nguvu ya kukatia kwenye zana.<\/li>\n<li>Muhimu zaidi, nguvu iliyobadilika hufanya kazi ili <em>add energy<\/em> kwenye mfumo, ikisukuma sehemu zaidi katika mwelekeo ambao ilikuwa inakwenda tayari.<\/li>\n<li>Mwendo ulioongezeka huzalisha nguvu kubwa zaidi, ambayo inaongeza nishati zaidi \u2014 na mzunguko unarudia.<\/li>\n<\/ol>\n<p>Mzunguko huu husukuma amplitude juu hadi usimamishwe na usio-mstari ndani ya mfumo (rotor kugonga kikwazo kigumu, muhuri kufunga pengo) au hadi kitu kiharibike. Ufahamu muhimu wa kimwili ni wa usawa wa nishati: kutokuwa na utulivu hutokea wakati nguvu inayotegemea mwendo inalisha nishati kwa kasi zaidi kuliko <a href=\"https:\/\/vibromera.eu\/sw\/glossary\/damping\/\">damping<\/a> inaweza kuipunguza. Unyevu wa kutosha ndiyo mstari wa kwanza wa ulinzi dhidi ya kujichochea.<\/p>\n<h2>2. Mifano ya Kawaida ya Mtetemo wa Kujichochea<\/h2>\n<p>Matukio kadhaa yanayojulikana sana katika uchunguzi wa mashine ni mifano ya kiada ya mtetemo wa kujichochea:<\/p>\n<ul>\n<li><strong><a href=\"https:\/\/vibromera.eu\/sw\/glossary\/oil-whirl\/\">Oil whirl<\/a> and oil whip:<\/strong> mifano ya kawaida zaidi katika mashine zinazozunguka. Katika beari ya jarida la filamu ya maji, shimoni inayozunguka huvuta mafuta kwenye kabari inayobeba mzigo. Msukosuko unaweza kusababisha kabari yenyewe kuzunguka (whirling) karibu na beari; shinikizo kutoka kwa kabari hiyo inayozunguka husukuma shimoni, ikiongeza nishati zaidi kwenye mzunguko. Mtetemo unaotokana na hilo hauko kwenye kasi ya uendeshaji bali kwenye <a href=\"https:\/\/vibromera.eu\/sw\/glossary\/sub-synchronous\/\">sub-synchronous<\/a> mzunguko, kwa kawaida 0.42\u20130.48&times; <a href=\"https:\/\/vibromera.eu\/sw\/glossary\/running-speed\/\">running speed<\/a>. Iwapo mzunguko wa whirl utapanda hadi kufikia <a href=\"https:\/\/vibromera.eu\/sw\/glossary\/natural-frequency\/\">frequency asili<\/a>, unajifungia na kuongezeka hadi kuwa <a href=\"https:\/\/vibromera.eu\/sw\/glossary\/shaft-whip\/\">whip<\/a> condition.<\/li>\n<li><strong>Mtetemeko wa kukata (Chatter) katika utengenezaji:<\/strong> katika kugeuzageuzwa au kusagwa, mtetemeko wa kukata huanza wakati zana ya kukata inaanza kutetemeka. Mtetemo huo husababisha unene wa chip kubadilika, unene unaobadilika wa chip husababisha nguvu ya kukata kutetereka, na nguvu inayotetereka hulisha nishati tena kwenye mtetemo wa zana \u2014 ukiukuza hadi kuwa mtetemeko mkali, unaojiendesha mwenyewe ambao unaharibu usafi wa uso na zana.<\/li>\n<li><strong>Flutter ya anga (Aerodynamic flutter):<\/strong> mtetemo wa kuinama-na-kupinda wa bawa la ndege (au msumari wa turbine) ambapo mwendo hubadilisha sura ya anga, sura iliyobadilika hubadilisha shinikizo la hewa, na shinikizo lililobadilika hulisha nishati tena kwenye mwendo \u2014 na kusababisha kushindwa kwa maafa ikiwa haitudhibitiwa.<\/li>\n<li><strong><a href=\"https:\/\/vibromera.eu\/sw\/glossary\/rotor-rub\/\">Rotor rubs<\/a>:<\/strong> rotor inapogusa sehemu ya kukaa, msuguano kwenye mgusano hupasha joto rotor kienyeji na kuinamisha. Kuinama kunaiongezea nguvu ya mgusano, ambayo huongeza joto na kuinama, na kuunda mzunguko wa maoni ya joto ambao unaweza kuendelea hadi kushikamana.<\/li>\n<\/ul>\n<p>Binamu wawili zaidi wanaochochewa na maji wanaostahili kujua ni <a href=\"https:\/\/vibromera.eu\/sw\/glossary\/steam-whirl\/\">steam whirl<\/a> katika turbine na familia pana ya kutokuwa na utulivu kunakoendeshwa na mtiririko wa <a href=\"https:\/\/vibromera.eu\/sw\/glossary\/aerodynamic-forces\/\">nguvu za aerodynamic<\/a>, zote mbili zinazotii mantiki sawa ya mrejesho wa nishati.<\/p>\n<h2>3.

Sifa Muhimu na Uchunguzi<\/h2>\n<p>Mitetemo inayojitesha huwa na alama za kipekee kwenye <a href=\"https:\/\/vibromera.eu\/sw\/glossary\/spectrum\/\">Wigo wa FFT<\/a>:<\/p>\n<ul>\n<li><strong>Mzunguko usio-sawazishaji:<\/strong> mtetemo mara nyingi si mzidishaji wa nambari nzima au mzunguko wa kasi ya uendeshaji. Kwa kawaida hukaa kwenye mzunguko chini ya usawazishaji.<\/li>\n<li><strong>Instability:<\/strong> ukubwa wa mtetemo unaweza kuwa na msongo mkubwa sana na unaweza kupanda haraka kwa mabadiliko madogo ya kasi, joto au mzigo.<\/li>\n<li><strong>Sudden onset:<\/strong> mtetemo unaweza kutokuwepo kabisa hadi mashine ivuke kasi au kiwango fulani cha mzigo \u2014 mara nyingi unahusiana na <a href=\"https:\/\/vibromera.eu\/sw\/glossary\/critical-speed\/\">critical speed<\/a> \u2014 wakati ambapo unaonekana ghafla na kwa ukubwa mkubwa.<\/li>\n<\/ul>\n<p>Utambuzi wa hitilafu unahusisha kutambua vilele visivyo vya usawazishano na kisha kufikiria kuhusu mfumo wa kimwili unaoweza kusababisha msisimko huo katika mashine maalum. Kwa sababu mwanzo wake unahusiana na hali za uendeshaji, rekodi inayobadilisha kasi ni ya kufunua zaidi: a <a href=\"https:\/\/vibromera.eu\/sw\/glossary\/cascade-plot\/\">cascade plot<\/a> iliyochukuliwa wakati wa kuongezeka kwa kasi au kupungua kwa kasi inaonyesha sehemu ndogo ya usawazishano ikionekana na kisha kushika mzunguko wa asili, ambayo ni alama isiyoweza kukosea ya mzunguko wa whirl kugeuka kuwa whip. Kwa visa vinavyohusiana na beari, a <a href=\"https:\/\/vibromera.eu\/sw\/calculators\/journal-bearing-frequencies\/\">calculator ya journal-bearing defect-frequency<\/a> husaidia kuthibitisha kama kilele cha kushukiwa kinaanguka katika bendi ya oil-whirl. Neno pana linaloelezea tabia hii yote ni <a href=\"https:\/\/vibromera.eu\/sw\/glossary\/rotor-instability\/\">utendaji wa rotor<\/a>, na kutofautisha hilo na mwitikio wa kulazimishwa ni hatua ya kwanza na muhimu zaidi kwa mchambuzi \u2014 kwa sababu tiba ni tofauti kabisa: mtetemo wa kulazimishwa hupunguzwa kwa usawazishaji au urekebishaji wa mstari, ilhali msisimko wa kujisukuma lazima uondolewe kwa kubadilisha umbo la beari, nafasi, mzigo au unyakuzi.<\/p>\n<h2>5. Kwa Nini Haiwezi Kutibiwa kwa Usawazishaji<\/h2>\n<p>Onyo la vitendo linatokana moja kwa moja na fizikia. Kwa sababu mtetemo wa kujisukuma si jibu kwa doa zito linalozunguka, hauwezi kutibiwa kwa kuongeza uzito wa marekebisho \u2014 nishati inatolewa na maji ya beari, mchakato wa kukata au mtiririko wa hewa, si na usawa usio sawa wa misa.
