摘要
将自由活塞膨胀机和直线发电机耦合成新型自由活塞膨胀机-直线发电机(free piston expander-linear generator,FPE-LG),用于小型车用有机朗肯循环(organic Rankine cycle,ORC)余热回收系统;基于压缩空气试验平台和Matlab/Simulink软件对FPE-LG进行试验和仿真研究。在相对低的进气压力和工作频率下,FPE-LG的运动特性和输出特性的试验与仿真结果吻合性较好,有效验证了仿真模型的正确性。进而利用FPE-LG仿真模型进行相对高压和高频的仿真研究,结果表明:进气压力和工作频率对FPE-LG的运动特性、输出特性和指示效率具有重要影响。当进气压力为1MPa,工作频率为15Hz,外接电阻阻值为9Ω时,FPE-LG的峰值功率约为676W。
This paper presented a new free piston expander-linear generator (FPE-LG)for small-scale organic Rankine cycle (ORC)waste heat recovery system.A FPE-LG experimental test rig was developed and a simulation model based on Matlab/Simulink was established.The simulation model was validated with respect to the experimental results at relatively high intake pressure and operating frequency.Further investigation on the motion characteristics and output performance of FPE-LG were conducted with relatively high intake pressure and operating frequency based on the simulation model.The results show that the intake pressure and operating frequency have a great effect on the motion characteristics and output performance.The peak power output is 676W when the intake pressure,external load resistance,and operating frequency are 10bar,9Ω and 15Hz,respectively.
