摘要：

In order to study the vibration displacement phase characteristics of free piston Stirling engine, a coupled thermodynamic and dynamic calculation model of the engine was established. The pressure wave is linearized in the model, and the formula for calculating the phase between the vibration displacements of the two pistons of a free piston Stirling engine is obtained. The influence of main parameters on engine phase angle is analyzed. It is found that the free piston Stirling engine must satisfy the phase relation of valve piston displacement leading power piston displacement when the engine can start in a certain range of inflating pressure. The change of load resistance will change the electromagnetic damping coefficient, and then affect the phase relationship. The stiffness of the power piston leaf spring has little effect on the phase angle, while the stiffness of the valve piston leaf spring has greater effect on the phase angle. © 2019, Editorial Board of Journal of Huazhong University of Science and Technology.
