Vibration absorber for a free piston stirling engine
The Journal of the Acoustical Society of America, 1986A free piston Stirling engine has a hermetic vessel containing a displacer piston and a power piston coupled to each other and to the vessel by gas springs. An additional mass is coupled to the vessel by a gas spring which is tuned to the operating frequency of the engine geometrically.

Gas action effect of free piston Stirling engine
Energy Conversion and Management, 2016Abstract Gas action effect of free piston Stirling engine (FPSE) is very important to solve the key problem of start-up and find the way to increase its efficiency. The gas force is a key force to free FPSE. In this paper, the gas action effect has been analyzed by the method of rotation vector decomposition. It is found that the gas forces of piston

Reflections on Free-Piston Stirling Engines, Part 1: Cyclic Steady Operation
Journal of Propulsion and Power, 1998Abstract: In spite of the conceptual simplicity, the design of the free-piston Stirling engines (FPSEs) is made difficult by the necessity to accurately foresee the effect of the various geometric, dynamic, and thermodynamic variables on their behavior. This paper describes a fully developed mathematical model able to characterize these machines taking
