而前人對挖掘機(jī)能量回收的相關(guān)研究表明，在挖掘機(jī)的可回收能量中，動臂和斗桿的同收能量約占70%以上，因此勢能回收應(yīng)是挖機(jī)能量回收的重點(diǎn)。研究表明，對挖掘機(jī)工作裝置進(jìn)行勢能回收需要解決的難點(diǎn)問題主要有三個(gè)：首先，由于將一部分油液能量轉(zhuǎn)換成了電能，勢能回收對整機(jī)的速度穩(wěn)定性和操控性有較大的負(fù)面影響；其次，挖掘機(jī)工作過；中工作裝置下放時(shí)間短（通常為2～3s），因此短時(shí)間內(nèi)完成具有較強(qiáng)沖擊性勢能的回收對相應(yīng)的回收元件有很高的要求；最后，通常的挖掘機(jī)勢能回收系統(tǒng)動態(tài)響應(yīng)特性差，回收時(shí)間長，效率低。

雙圓筒依靠聯(lián)接板固定成一體，聯(lián)接板上同時(shí)固定著激振器，且激振器需通水冷卻，雙圓筒由隔振彈簧支承，彈簧支座固定在不參振的底架上。圓筒筒體由外筒內(nèi)襯筒和端蓋組成。
要增加新的表面積，必須克服固體分子間的結(jié)合力，因而需消耗能量。
