Summary

The machine was designed based upon the numerical results of a dynamic analysis method. The method included the effect of self-excitation vibration with dissipation caused by the flow friction of an oscillating working gas flow and solid friction of seals. It was found that the design values of reciprocating masses and spring constants proposed in published papers related to the study were suitable for practical use. The fundamental effects of heat exchanger elements on dynamic behaviours of the machine were clarified. It has been pointed out that some improvements were required for thermodynamic analysis of heat exchangers and working spaces.
