In the experiment, the standardized alcohol lamp was used as the heat source, and the parameters such as heat input, mechanical output power and power generation power were collected in real time through the thermodynamic test system. The influence of relevant kinetic parameters on the performance of the Stirling engine was analyzed in detail. With the help of the whole chain evaluation model of thermodynamics-mechanical transmission-power generation system, the dual application value of this type of heat engine in distributed energy system and engineering education field is confirmed. The research can provide data support for the structural optimization design of Stirling engine, and the developed experimental device can be used in the demonstration experiment teaching of college physics.
