Reflections on Free-Piston Stirling Engines, Part 2: Stable Operation
Journal of Propulsion and Power, 1998Abstract: In this paper a new linearization technique of the dynamic balance equations of a free-piston Stirling machine is developed. It takes into account the non-linear thermo-fluid-dynamic terms inherent in the machine, while keeping the linearity of the differential dynamic equations.

Dynamic analysis of a simplified free-piston Stirling engine
SIMULATION, 1980Lumped-volume dynamic equations are derived using an energy-state formulation. This technique requires the writing of state functions for kinetic and poten tial energy. A Rayleigh dissipation function accounts for losses in the system. Using these functions, a Lagrangian is formed and the equations of motion for the system are derived.

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.
