Hopf Instabilities in Free Piston Stirling Engines
Journal of Computational and Nonlinear Dynamics, 2013Free piston Stirling engines (FPSEs) are examples of closed cycle regenerative engines, which can be used to convert thermal energy into mechanical energy. These engines are multidegree-of-freedom dynamical systems, which are designed to operate in a periodic manner. Traditionally, for design purposes, linear models are used and the associated periodic

Regenerator Losses in a Free Piston Stirling Engine
2016Due to the need for alternative means that can be used to generate power with high efficiency and less harm to the environment, the free piston Stirling engine has emerged and research has been carried out to prove its relevance. This study is carried out in the thermal energy conversion unit, using solar energy to generate power.

Structural design of Stirling engine with free pistons
AIP Conference Proceedings, 2014Stirling engine is a device that converts thermal energy to mechanical work, which is mostly used to drive a generator of electricity. Advantage of Stirling engine is that it works with closed-cycle, where working medium is regularly cooled and heated, which acts on the working piston. This engine can be made in three modifications - alpha, beta, gamma.

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.
