Puas muaj lwm yam kub khiav kev co?

Case 1: Cov tsos mob tsis zoo yog tshwm sim los ntawm qhov kub khiav kev co hauv 3C nyias- cov khoom siv phab ntsa.

Tom ntej: Txawb xov tooj charger casings nrog nyias phab ntsa (tsuas yog 0.8 hli tuab) yog ua los ntawm 3C electronics cog. Thaum ib zaug xwb -nozzle kub khiav yog siv rau kev txhaj tshuaj ncaj qha, cov khoom nto feem ntau qhia tau hais tias alternating ci thiab tsaus vibration cim thaum lub sij hawm ntau lawm. Qhov no tuaj yeem ua rau qhov tsis ua tiav txog li 22%, tag nrho ua tsis tau raws li cov qauv pom.

Ua rau kev vibration: Kev txhaj tshuaj siab heev yog tsim nyog rau nyias -walled txhaj. Cov kua dej pulsation yog tsim los ntawm qhov siab - ceev yaj taug kev los ntawm lub taub hau kub. Qhov no pulsation ua rau siab - zaus vibration vim qhov kub nozzle tsis yog tus kheej damped thiab ruaj (qhov ntsuas zaus mus txog 42Hz, tshaj qhov kev nyab xeeb). Lub sijhawm vibration qhabnias tau tso rau ntawm qhov khoom ntawm qhov chaw vim tias qhov kev vibration no tau pauv mus rau lub pwm kab noj hniav tam sim ntawd.

Kev daws: Txhawm rau txo lub nozzle kev vibration amplitude, lub siab - kub resistant stainless hlau dampening tes tsho raug ntsia rau ntawm lub taub hau kub. Raws li qhov tshwm sim, qhov kev txhaj tshuaj ceev tau qis dua ntawm 120 mm / s mus rau 85 mm / s. Tom qab kev kho, qhov tsis xws luag poob qis dua 0.3%, qhov kev vibration zaus poob mus rau 18Hz, thiab cov cim vibration ploj tag nrho.

Case 2: Resonance Failure tshwm sim los ntawm Active Vibration- Pab Kub khiav Parameter yuam kev

Tom qab: txhawm rau ua kom cov dej ntws tau siab dua - cov khoom siv melts, cov khoom siv tshiab hloov kho qhov chaw txhaj tshuaj moulding tau yuav lub tshuab kub khiav nrog kev vibration nquag . 50 Hz tau xaiv los ua qhov kev vibration zaus. Cov kub khiav manifold cov ntsia hlau txuas tag nrho tau tawg, lub cua sov coil sib cais, thiab lub kaw lus tsis tuaj yeem ua haujlwm tom qab tsuas yog peb hnub ntawm kev sim ntau lawm.

Kev vibration ua rau: Lub kaw lus resonance tshwm sim los ntawm cov nquag vibration zaus ntawm 50 Hz coinciding nrog cov kub khiav manifold lub inherent zaus. Kev ntxhov siab tau nce los ntawm qhov siab - zaus resonance, uas sai sai ua rau hlau qaug zog tawg.

Txhawm rau kom tsis txhob muaj qhov resonance ntau, lub manifold tau rov tsim dua thiab nws cov zaus zaus tau hloov mus rau 70 Hz. Lub zog vibration zaus raug txo mus rau 25 Hz tib lub sijhawm. Tsis muaj kev vibration-induced structural puas tau tshwm sim nyob rau hauv peb lub xyoos tom ntej no ntawm ntau lawm, thiab lub active vibration lub peev xwm los txhim kho flowability persisted.
