摘要
在许多机械装备中,大惯量高频启停回转机构中存在能量损耗大、资源利用率低及启制动性能差等问题,为此,对回收大惯量高频启停回转机构制动能量的节能驱动技术进行了综述。首先,介绍了传统液压驱动回转机构的工作原理,以及造成能量浪费的原因;然后,从液压式储能、电力式储能、电液式储能和机械式储能出发,分别介绍了国内外关于大惯量高频启停回转机构节能驱动技术的研究成果;最后,分析总结了这4种方式各自的优、缺点。研究结果表明:在现有节能系统中,通过增加相关储能元件来实现能量回收的技术存在一定的问题(比如元件本身存在能量消耗、增加的元件会增加系统复杂度、储能过程中能量转换过程也存在能量损失),因此,减小节能驱动系统中增加的元件数量、改进并提升元件性能、完善不同元件之间的匹配性是节能驱动技术的重点及难点;研制新型高效储能元件、实现大惯量高频启停回转机构节能驱动过程集成化、将智能算法与能量回收技术相结合是节能驱动技术未来的发展趋势。
Aiming at the problems of large energy loss,low resource utilization and poor starting and braking performance in the large inertia high-frequency start-stop slewing mechanism in mechanical equipment,the energy-saving drive technology for recovering the braking energy of the large-inertia high-frequency start-stop slewing mechanism was reviewed.Firstly,the working principle of the traditional hydraulically driven slewing mechanism and the causes of energy waste were introduced.Then,the research results of energy-saving drive technology for large inertia high-frequency start-stop slewing mechanisms at home and abroad were introduced from four aspects:hydraulic energy storage,electric energy storage,electro-hydraulic energy storage and mechanical energy storage.Finally,the advantages and disadvantages of these four aspects were analyzed and summarized.The research results show that there are certain problems in the technology of realizing energy recovery by adding related energy storage elements in the existing energy-saving systems:the elements themselves have energy consumption,the added elements can increase the complexity of the system,and the energy conversion process during the energy storage process also has energy loss.Therefore,reducing the number of components added in the energy-saving drive system,improving and enhancing the performance of the components,and improving the matching between different components are the key points and difficulties of the energy-savingdrive technology.Developing new high-efficiency energy storage components to realize the integration of energy-saving drive process of large inertia and high-frequency start-stop slewing mechanism,and combining intelligent algorithms with energy recovery technology become a new development trend of energy-saving drive technology.
