摘　　要：针对液压提升装置下行过程中负载重力势能转化为热能耗散的问题,提出了一种新型的全液压势能回收系统。介绍了新型势能回收系统的结构和工作原理,并对势能回收系统中液压蓄能器、液压泵/马达及其变量机构的参数进行匹配。应用AMESim建立仿真模型,对系统的操控性能和势能回收效果进行仿真研究。结果表明,新型势能回收系统能够实现液压提升装置重力势能的回收,势能的回收效率随着负载的增大而提高,并逐渐趋于稳定。系统操控性能良好,能够控制液压提升装置以不同速度稳定下行,不受负载大小的影响。In order to solve the case of load gravitational potential energy changing into heat in the hydraulic lifting device decline process, a new full hydraulic gravitational potential energy recovery system is proposed. The structure and working principle of the energy recovery system are introduced. The key parameters of the hydraulic accumulator, hydraulic pump/motor and variable mechanism are matched. Simulation model is built by AMESim, and then system performance and energy recovery efficiency are analyzed. The results show that the new energy recovery system can recycle the load potential energy, and potential energy recovery efficiency increases with load increasing and gradually tends to a stable value. The system is well-controlled, allows the hydraulic lifting device to decline stably at different speed , and the speed is not affected by the load.
