Summary

Dynamic motion of displacers and basic performance characteristics of a free piston Vuilleumier heat pump during forced vibration were investigated experimentally and compared with second order simulation results. Sensitivity studies were conducted with respect to key operational and environmental parameters such as driving frequency, hot gas temperature, motor input, phase angles and strokes. The dependence of the phase angle on the driving frequency of the hot displacer was the reverse of that of the driving frequency of the cold displacer. The simulation results were qualitatively in good agreement with the results of the experiments.
