Kwimveliso echanekileyo, ukulinganisa kunye neminye imimandla, ukuzinza kwezixhobo kubaluleke kakhulu, kwaye i-vibration attenuation ikhono lichaphazela ngokuthe ngqo ukusebenza okuzinzileyo kwezixhobo. Iqonga le-Granite kunye nesiseko sentsimbi yentsimbi zizinto eziqhelekileyo ezixhasayo zesakhiwo, umahluko we-vibration attenuation coefficient inempembelelo ebalulekileyo ekusebenzeni ngokuchanekileyo kunye nokuthembeka kwezixhobo.
1. Inkcazo emfutshane yomgaqo wokuthotywa kwe-vibration
Ukungcangcazela kubhekiselele kwinkqubo apho into isebenzisa amandla ayo okungcangcazela emva kokuba ivuselelwe kukungcangcazela kwangaphandle, kwaye i-vibration amplitude iyancipha kancinci kancinci. Ikhono lokuthomalalisa i-vibration limiselwa yisakhiwo sangaphakathi kunye neempawu zokudambisa izinto. I-coefficient yokunciphisa i-vibration ephezulu ithetha ukuba i-material inokuguqula ngokufanelekileyo amandla okungcangcazela kwezinye iindlela zamandla (ezifana nobushushu), ezinokucinezela ngokukhawuleza ukungcangcazela.
2. Iimpawu zokunciphisa i-Vibration yeqonga legranite
I-Granite luhlobo lwelitye lendalo, ingaphakathi layo lenziwe ngeekristale zamaminerali adityanisiweyo ngokuqinileyo. Esi sakhiwo sishinyeneyo nesintsokothileyo sinika igranite iipropati ezilungileyo zokuthomalalisa ukungcangcazela. Xa i-vibration yangaphandle idluliselwa kwi-platform ye-granite, i-friction encinci phakathi kwe-crystals kunye nokusebenzisana phakathi kwee-particles zamaminerali zinokuthatha ngokufanelekileyo kwaye zichithe amandla okugubha. Uphando lubonisa ukuba i-vibration attenuation coefficient ye-granite idla ngokuba phakathi kwe-0.01 kunye ne-0.02 (igranite yemvelaphi eyahlukileyo kunye nokwakheka kuya kwahluka kancinci). Kwizixhobo zokulinganisa ezichanekileyo, ezifana nesixhobo sokulinganisa ukulungelelanisa sixhotyiswe ngeqonga legranite, nokuba kukho ukuphazamiseka kwe-vibration okubangelwa ukusebenza komatshini omkhulu ojikelezayo, iqonga legranite linokunciphisa ngokukhawuleza ukunyakaza, ukwenzela ukuba i-probe yesixhobo sokulinganisa sihlale sizinzile, ukuqinisekisa ukuchaneka kwedatha yokulinganisa. Ngokomzekelo, kwi-workshop yokuvelisa i-electronic chip, i-vibration yendalo inzima kakhulu, kwaye iqonga legranite linokunciphisa i-amplitude ye-vibration engenayo ngaphezu kwe-80% ngexesha elifutshane, ukubonelela ngesiseko esizinzile sokulinganisa okuchanekileyo kwindlela yokuvelisa i-chip.
3. Iimpawu zokunciphisa i-Vibration yesiseko sentsimbi
Intsimbi yokuphosa i-alloy material esekelwe kwintsimbi, yongeza i-carbon, i-silicon kunye nezinye izinto. Ine-flake okanye i-spherical graphite structure ngaphakathi, esebenza njenge-dampener ukuya kwinqanaba elithile kwaye inceda ukunciphisa ukungcangcazela. I-vibration attenuation coefficient ye-grey cast iron yesiqhelo imalunga ne-0.005-0.01, kwaye ukusebenza kwe-vibration attenuation ye-ductile cast iron iye yaphuculwa ngenxa yokusabalalisa kwayo okungqukuva kwegraphite kunye nesakhiwo esifanayo, kwaye i-coefficient yokunciphisa inokufikelela kwi-0.01-0.015. Kwizixhobo zesixhobo somatshini, isiseko sentsimbi ephosiweyo sinokunciphisa ngokufanelekileyo ukungcangcazela okubangelwa yimikhosi yokusika ngexesha lokusebenza komatshini. Nangona kunjalo, xa kuthelekiswa neqonga legranite, isiseko sentsimbi etyhidiweyo ebusweni be-high-frequency, high-intensity vibration, vibration attenuation rate icotha kancinci. Ngokomzekelo, kwinkqubo yokugaya isantya esiphezulu, xa isantya sokusika sidlula umda othile, nangona isiseko sentsimbi sinokunciphisa inxalenye ye-vibration, kusekho inani elincinci le-vibration eseleyo ethunyelwa kwisixhobo somatshini, echaphazela ukugqiba komgangatho owenziwe ngomatshini, kwaye iqonga legranite linokugcina uzinzo kule meko.
4. Uhlalutyo lokuthelekisa
Ukususela kuthelekiso lwedatha, i-vibration attenuation coefficient yeplatifomu yegranite iphezulu kunesiseko sentsimbi, oku kuthetha ukuba phantsi kwendawo yokungcangcazela efanayo, iqonga legranite linokunciphisa ukungcangcazela ngokukhawuleza nangempumelelo. Kwiimeko ezineemfuno zokulawula ukungcangcazela okuphezulu, njengezixhobo ezichanekileyo ze-optical precision kunye ne-ultra-precision machining equipment, iingenelo zeplatifti zegranite zibonakala ngokucacileyo, ezinokuthi zinike indawo yokusebenza ezinzileyo yezixhobo kunye nokuqinisekisa inkqubela phambili echanekileyo yokusebenza okuphezulu. Isiseko sesinyithi esinexabiso eliphantsi, inkqubo yokuphosa evuthiweyo kunye nezinye iimpawu, kwezinye iimfuno zokuthotywa kwe-vibration azikho rhabaxa kangako, kwaye ingqalelo kulawulo lweendleko zokwenziwa koomatshini ngokubanzi, izixhobo zoshishino ngokubanzi zisetyenziswa ngokubanzi.
Kwizicelo ezisebenzayo, kuyimfuneko ukukhetha iqonga legranite okanye isiseko sentsimbi ngokweemfuno ezithile zesixhobo, indawo yokusebenza kunye nohlahlo lwabiwo-mali lweendleko, ukuze kuphunyezwe eyona mpembelelo intle yokuthomalalisa i-vibration kunye neenzuzo zoqoqosho.
