Piezo element pomoc

Submitted by vlada.yahoo on Wed, 15/07/2009 - 06:34

Postovana gospodo, nadam se da mozete da mi pomognete. Potrebna mi je piezo elektricna plocica odredjenih karakteristika. Tacnije, kada dovedem napon na plocicu da imam neko mehanicko pomeranje sa nekim sto vecim hodom do npr 0.5cm ako je to moguce i odredjenom frekvencom oscilovanja. Gde bih mogao da nadjem tako nesto, odnosno kome da se obratim za pomoc?

Unapred zahvalan,

Vlada

Ja mislim da je moguc samo obrnut proces...Piezo efekat je je efekat kod koga se mehanickim delovanjem na piezo element dobija napon...ali obrnut proces nije moguc,koliko ja znam...neka me neko ispravi ako nisam u pravu...

Postoje piezoelektrični aktuatori koji rade baš ono što vlada.yahoo traži. Ako znaš engleski traži specifikacije za "piezoelectric actuator" na guglu. Nikad se nisam u praksi sretao sa njima ali mislim da je pomeraj od 0.5cm previše, oni se koriste za mala pomeranja.

Edit: pravopis

Svaki biper je ustvari piezo pločica. Ono tit-tit koje se čuje kad se pritisne taster na telefonu, kalkulatoru i sličnim uređajima je piezo element na koji se dovede napon određene frekvencije.

Znam da je EI Nis proizvodio ultrazvucne kade za ciscenje (u kojima je glavni dio piezzo-element) raznih velicina, pa mozda da potrazis u tom smjeru, naravno neces imati pomak od 0,5cm.
Za sta ti treba takvo nesto?

Mala digresija, u te ultrazvucne kade su stavljali mlado vino i posle nekoliko minuta znalci su pricali kao da je vino staro desetak godina, izvanrednog kvaliteta.

Elem, nije bitan hod, potrebna mi je periodicna mehanicka sila koju ce piezo element da izvrsi na objektu (odnosno koliku silu moze da proizvede element) kada mu se dovede napon (struja). Trebaju mi parametri 1. (dinamicki) frekvencije mehanickog oscilovanja membrane i sile koju moze da proizvede element, 2. (elektricni) U zavisnosti od napona i struje, tacnije granice.
