摘  要:
根据自由活塞式内燃发电机的运行原理,建立了基于动力学和热力学方程的自由活塞式内燃发电机动力学模型。通过对动力学模型的数值求解,获得了系统的动态特性,并进一步分析了质量、输入能量、点火位置、负载等对系统性能的影响,同时对系统频率特性进行了研究。研究结果表明系统为自激系统,通过输入参数的合理控制,可实现系统稳定频率下的运行。

摘  要:
A dynamic model of a free piston generator(FPG) was developed considering the operation principle of FPG based on dynamics and thermodynamics equations.Then the dynamics characteristic of FPG has been achieved through the numerical solution of the dynamic model.Furthermore the influence of the input parameter of FPG system characteristics and the frequency characteristic were discussed.The results showed that FPG is a self-exciting system and stable performance could be achieved by appropriate control.
