Résumé

Theoretical analyses and modeling are conducted on dynamic and thermodynamic characteristics of the moving-coil linear compressor in the Stirling-type pulse tube cryocooler. Governing equations are deduced, and f and ?P are found to be the two key parameters connecting compressor to pulse tube cold finger. An improved ECA model is developed to investigate the cold finger characteristics and their influences on f, ?P. Systematic simulations based on a specific case are performed to provide elaborate explanations about the theoretical analyses with the frequency varying from 30?Hz to 100?Hz at 60?K, 80?K and 100?K, respectively. The variations of four important parameters of f, ?P, I and ?, and the compressor thermodynamic performances and the cryocooler cooling performances, with the frequency at above temperatures are simulated and analyzed, respectively. The effects of compressor geometrical parameters on ?motor are also simulated. The experimental verifications will be presented in Part 2.
