振動(dòng)臺(tái)由電動(dòng)機(jī)、齒輪同步器（也就是平時(shí)叫的協(xié)調(diào)箱）、激振器、聯(lián)軸器、振動(dòng)臺(tái)面以及彈簧和彈簧支座等共同構(gòu)成。其中，激振器是振動(dòng)臺(tái)的**，位于臺(tái)架的下方。振動(dòng)臺(tái)機(jī)器運(yùn)轉(zhuǎn)的時(shí)候，電動(dòng)機(jī)帶動(dòng)的帶動(dòng)下，兩組對(duì)稱的偏心塊就會(huì)運(yùn)動(dòng)，具有相同的頻率，但是轉(zhuǎn)動(dòng)的方向相反，這樣，在激振力的作用下，整個(gè)振動(dòng)臺(tái)就會(huì)進(jìn)行上下振動(dòng)了。 </p> <p> 振動(dòng)臺(tái)主要有3類：機(jī)械式振動(dòng)臺(tái)、液壓式振動(dòng)臺(tái)和電動(dòng)式振動(dòng)臺(tái)。 </p> <p> 機(jī)械式振動(dòng)臺(tái)是把機(jī)械能轉(zhuǎn)化成動(dòng)能。特點(diǎn)是：推力大、波形差、價(jià)格低廉，適用于低頻（5Hz-80Hz）疲勞實(shí)驗(yàn)。 </p> <p> 液壓式振動(dòng)臺(tái)是把液壓能轉(zhuǎn)換成動(dòng)能。特點(diǎn)是：低頻（**頻）、推力大、負(fù)載能力強(qiáng)、控制方便，但工作上限頻率低（一般以幾十Hz到幾百Hz為上限）價(jià)格昂貴。 </p> <p> 電動(dòng)式振動(dòng)臺(tái)是把電能轉(zhuǎn)換成動(dòng)能。特點(diǎn)是：工作頻率寬（從幾Hz到幾千Hz）波形好、控制方便、價(jià)格較貴，是一般試驗(yàn)室中例行試驗(yàn)**常用的品種。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px;
