摘要：
Mastering start-up characteristics is the premise to carry out experimental research on free-piston Stirling generators (FPSG). An experimental test system of FPSG was built to systematically study the start-up characteristics. It is found that the FPSG can be successfully started only when the temperature of the hot end exceeds a certain value after excited, by which the start-up temperature of the generator is defined. Then, taking the start-up temperature as the evaluation index, the influence of the parameters such as the charging pressure, displacer spring stiffness on the starting of the generator are analyzed. The experimental results show that the start-up temperature of the FPSG decreases gradually with the increase of the charging pressure. The generator can be started successfully only when the displacer spring stiffness is within a certain range, and there is an optimal value. At the same time, reducing the external load resistance and increasing the resonance of the system through the series capacitor are beneficial to the starting of the generator. © 2023 Science Press.
