Analysis of resonant frequency of moving magnet linear compressor of Stirling cryocooler.

Author(s) : XIA M., CHEN X.

Type of article: Article, IJR article

Summary

This paper analyzes resonant frequency of the moving magnet linear compressor of Stirling cryocooler. The CFD (computational fluid dynamics) and FEM (finite element method) are used for the analysis of resonant frequency with FLUENT 6.2 and ANSYS 11.0 and an experiment is designed for testing the resonant frequency of moving magnet linear compressor. Results from simulations and experiments showed that the resonant frequency of the moving magnet linear compressors is affected by the machine spring, the gas spring, the magnet spring, and the mass of moving assembly, while the resonant frequency of the moving coil linear compressors is only affected by the machine spring, the gas spring, and the mass of moving assembly.
