電磁式振動盤的工作原理：

振(zhen)(zhen)動盤(pan)是由振(zhen)(zhen)動板,電(dian)磁鐵(tie)(tie),銜(xian)鐵(tie)(tie),彈簧片,安裝(zhuang)座,減(jian)振(zhen)(zhen)膠墊組(zu)成,利(li)用(yong)控制器(qi)產生與系(xi)統固有頻率相同(tong)的脈(mo)沖電(dian)流(liu)使電(dian)磁鐵(tie)(tie)勵磁后,系(xi)統發生共振(zhen)(zhen),銜(xian)鐵(tie)(tie)及(ji)振(zhen)(zhen)動板會(hui)快(kuai)速的拉向電(dian)磁鐵(tie)(tie),因為(wei)下(xia)降速度很(hen)快(kuai),所以(yi)物(wu)(wu)(wu)料(liao)會(hui)浮(fu)在(zai)空中,并在(zai)重力作(zuo)用(yong)下(xia)落向料(liao)盤(pan),接(jie)著在(zai)彈簧片的作(zuo)用(yong)下(xia),銜(xian)鐵(tie)(tie)及(ji)振(zhen)(zhen)動板又被推(tui)回,這時使料(liao)盤(pan)內的物(wu)(wu)(wu)料(liao)向前(qian)方(fang)移動,該作(zuo)用(yong)以(yi)每分鐘3000---10000次(ci)或更高的次(ci)數反復進行,使用(yong)權料(liao)盤(pan)內的物(wu)(wu)(wu)料(liao)平滑移動.

交(jiao)流電(dian)(dian)壓使電(dian)(dian)磁(ci)(ci)(ci)鐵產(chan)生(sheng)(sheng)(sheng)(sheng)磁(ci)(ci)(ci)場,由于頻率很(hen)高,故產(chan)生(sheng)(sheng)(sheng)(sheng)的磁(ci)(ci)(ci)力也是(shi)瞬(shun)間變化(hua)的,底盤(pan)下面有3---6組一定的角度彈(dan)簧(huang)片(pian),當(dang)電(dian)(dian)磁(ci)(ci)(ci)鐵同交(jiao)流電(dian)(dian)瞬(shun)間產(chan)生(sheng)(sheng)(sheng)(sheng)磁(ci)(ci)(ci)場,彈(dan)簧(huang)片(pian)受壓,當(dang)電(dian)(dian)壓正弦波變化(hua)的時(shi)候,彈(dan)簧(huang)片(pian)彈(dan)回(hui)來(lai),就產(chan)生(sheng)(sheng)(sheng)(sheng)了力.
