A linear analysis model for a free piston Vuilleumier heat pump (FPVM) was constructed to derive closed form solutions for the operating frequency, phase angle and displacer strokes at self-excited operation and forced oscillation. Using the linear analysis, conditions for self-excited operation and the effects of connecting the hot displacer and the cold displacer by a spring on the dynamic motion of the displacers and the FPVM performance were investigated. Energy flow in the FPVM was also obtained. A simple 2nd order isothermal simulation combined with the linear analysis was developed which enabled culculation of the FPVM performance characteristics. It was found that the simulation results agreed well qualitatively with results of experiments at self-excited operation. The simulation was used to calculate the dependences of the dynamic motion of the displacers and the FPVM performance on the spring constants, displacer masses and damping coefficients.
