摘　　要：提出了一种新型基于斯特林循环的热驱自由活塞反渗透海水淡化动力系统,采用自由活塞发动机,取消曲柄连杆等刚体传动机构,利用非刚性介质海水作为活塞平移机械能的接受体,简化传动链,通过蓄能器和配合弹簧作用,能够提供稳定输出功。通过AMESIM软件对动力系统的泵腔进行仿真研究,分析其活塞组件的运动特性及泵腔的流量特性。结果表明,动力系统自由活塞泵可以稳定运行,有稳定输出功,设计比较合理,具有可行性。A new type heat-driven free piston reverse osmosis desalination power system based on Stirling cycle has been put forward.By applying free piston engine and removing crank rod and other rigid transmission mechanism,taking nonrigid medium seawater as the acceptor of piston translational mechanical energy and simplifying transmission chain,steady output power could be provided by accumulator and spring.Simulation research on the power system pump cavity has been carried out by AMESIM software to analyze motion characteristics of piston components and flow characteristics of pump cavity,the results showed that the power system free piston pump could operate stably and has steady output power,the design is reasonable and feasible.
