Thaum ib yam khoom vibrates, nws ua rau kev txav ntawm cov huab cua nyob ib puag ncig. Cov molecules no tsoo rau hauv cov molecules ze ntawm lawv, ua rau lawv vibrate ib yam nkaus. Qhov no ua rau lawv tsoo rau hauv cov huab cua nyob ze dua. Qhov "cov tshuaj tiv thaiv kab mob" no, hu ua suab nthwv dej, txuas ntxiv mus kom txog thaum cov molecules khiav tawm ntawm lub zog.
Cov khoom vibrating li cas?
Ib qho khoom vibrating txav rov qab los ntawm nws qhov chaw nyob ruaj khov. Lub voj voog ua tiav ntawm kev vibration tshwm sim thaum cov khoom txav los ntawm ib txoj hauj lwm huab mus rau lwm qhov kawg, thiab rov qab los dua. Tus naj npawb ntawm cov voj voog uas cov khoom vibrating ua tiav hauv ib thib ob yog hu ua zaus.
3 yam uas vibrate ua suab yog dab tsi?
Peb yam vibrate thaum lub suab tsim:
- qhov khoom.
- cov molecules hauv huab cua (lossis lwm qhov nruab nrab xws li dej)
- pob ntseg.
Peb hom kev vibration yog dab tsi?
Machinery Vibrations tuaj yeem muab faib ua peb hom, nyob ntawm seb qhov kev vibrations:
- Torsional vibration.
- Axial lossis Longitudinal Vibration.
- Kev vibration tom qab.
Kev vibration yog dab tsi?
Cov tsis tseem ceeb ntsig txog kev vibration pickups / vibrometers tau piav qhia hauv qab no: (1) Vibration zaus Unit: Hz (Hertz) Cim: f Hais txog tus lej ntawm lub sijhawm vibrating khoom vibrates ib ob. Covinverse of a vibration zaus yog hu ua lub sij hawm (T), T=1 / f.
