Abstract

This work presents the ideal adiabatic model of the Stirling engine which was combined with the dynamic model of the piston-crankshaft system with three degrees of freedom. On the basis of the conducted thermodynamic analysis for the working space in the Stirling engine, and on the basis of the physical model of the working mechanism (constructed with the assumption of the static mass reduction), a multidomain simulation model has been developed, using the Matlab&Simulink software. On the basis of the derived equations of energy conservation for the thermodynamic model, as well as equations of motion for the mechanical model, the influence of chosen thermodynamic and mechanical parameters have been analysed, among others: influence of the temperature of the upper heat source on the theoretical work and power gain, of the temperature changes in the compression and expansion space in the course of the working cycle on the simulation model behaviour, whose input parameters correspond to the real object – the Stirling engine. As a result of the performed simulations, additionally: the flow of the working gas mass at the control borders, and the influence of the transient states on the pressure curve were presented among others. The results discussed in this work convey practical information about the thermodynamic and dynamic properties of the simulated real object
