| 摘 要： | 提出采用激光多普勒效应测量GM低温制冷机振动，并搭建实验台测试了RDK-408S型GM制冷机各方向的振动大小。实验结果表明，型号为RDK-408S的GM制冷机振动频率约为1 Hz，轴线方向的振动最大，约为30 m，x方向也存在脉冲振动，达到30 m，都远远大于激光约束聚变研究中所需要的振动要求，必须采取具体措施进行减振或隔振。

| Abstract: | A method is proposed to measure the cryocooler vibration via the Doppler effect. Both axial and radial vibration of a typical G-M RDK-408S cryocooler is measured on the experimental setup. The experimental results indicate that the cryocooler has a working frequency of about 1 Hz. Compared with other directions, the axial direction vibration is the largest, which is about 30 m, while the radial direction also has pulse vibration，equivalent to that of the axial vibration. The experimental results are much larger than the vibration requirements in inertial confinement fusion research and therefore vibration reduction methods must be adopted. |
