给出了用来验证上两部分的大量系统试验结果,系统地研究并验证了整机内参数波动特征、压缩活塞与排出器之间的影响关系、冷头温度与调相器间隙对整机性能的影响,同时,以整机运行的冷头最低温度对其运行性能进行了检验,实时测量了各个气动腔内气体压力波动、排出器与活塞运动,这样有助于更加清晰地了解整机内部的工作机制。实验结果表明,试验数据与模拟结果吻合良好。 The results of a large number of system tests used to verify the above two parts are given. The fluctuation characteristics of the whole machine parameters, the relationship between the compression piston and the ejector are systematically studied and verified. The influence of the cold head temperature and the phase gap on the whole machine Performance of the machine at the same time, the operating temperature of the cold head of the minimum operating temperature of its performance were tested in real-time measurement of the gas pressure fluctuations in each pneumatic chamber, ejector and piston movement, which will help to more clearly understand the machine Internal working mechanism. The experimental results show that the experimental data agree well with the simulation results.
