电气传动与微电子技术飞跃发展使液压工程面临着新的挑战。怎样开发液压技术应使的新领域,巩固和提高它在工程控制系统中的地位,已成为当前亟待解决的问题。例如:在数控机床上,电气传动与液压传动不断竞争,交替发展,几经反复,电液伺服控制终于被电气伺服控制淘汰。这就使的一些人不得不担心,在其它场合电液伺服系统是否也会被取代。应该看到液压元件比电气元件使用的材料
The rapid development of electric drive and microelectronic technology has brought new challenges to hydraulic engineering. How to develop the new field that hydraulic technology should make, consolidate and improve its position in engineering control system has become the urgent problem to be solved. For example: In the numerical control machine tool, the electric transmission and the hydraulic transmission unceasingly competes, alternates development, after repeatedly, the electro-hydraulic servo control finally eliminated by the electrical servo control. This has led some people have to worry about, in other occasions, electro-hydraulic servo system will also be replaced. You should see the material used for hydraulic components over electrical components
