The change regulation of different chamber pressure, volume, mass flow, cycle work and other parameters were obtained based on the ideal adiabatic model, the internal alternating flow and heat transfer process of the β-type Stirling engine model GPU-3 were also analyzed. The results indicated that with the increased of the crank angle the pressure and volume curve of the working fluid were decreased at first and then increased; When ,the expansion chamber and the compression chamber temperature reached a maximum of 1057K and 388K, respectively. Meanwhile when , the mass flow and the heat exchange of the regenerator were largest compared to the other heat exchangers in this paper; The regulation of the cycle power of the expansion chamber and the curve of the total cycle power were same and both presented a sinusoidal curve change. Besides the movement of the working fluid can be reflected by the ideal adiabatic model actually compared with the Schmidt model in the Stirling engine. The multi-objective genetic algorithm was used to optimize the cyclic and the dimensionless work simultaneously, and the optimal results were 48344.6J and 1.412, respectively.
