启动是开展自由活塞斯特林发电机实验研究的前提,为更系统研究发电机的启动特性,搭建相关实验测试系统并开展实验。发现发电机在激励过后,只有热端温度超过一定值才能成功启动,并以此定义发电机的启动温度。然后以启动温度为评价指标,探究充气压力,配气活塞板弹簧刚度等参数对发电机启动的影响规律。实验结果表明：随着充气压力增加,发电机对应的启动温度逐渐降低。配气活塞板弹簧刚度只有在一定范围内,发电机才能成功启动,并存在最优值。同时,减小外负载阻值以及通过串连电容增加系统的谐振都有利于发电机的启动。
Abstract
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.
