Analysis and measurement of cryocooler vibration
摘要
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 μm, 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.关键词
