摘要
通过对双自由度斯特林制冷机振动系统模型的分析 ,建立了计算机仿真调相角模型。在模型求解过程中 ,通过改变弹簧参数来优化斯特林制冷机的压力波和制冷机回热器位移之间的相位差 ,使其接近最优相角要求 ,来辅助调节系统的工作参数。
Basing on conbination of themlodynamic and dynamic of FPST,it is concluded that the stability of FPST is correlated with flow-damping factor of regenerator,damping factor between the piston and the displacer reciprocating pairs and the rigidity of the spring, a model of the computer aided phase angle trimming procechure basing on the vibration system analyses of FPST has been established. Being compared with the result,both the simulation and the experimentation results coincided satisfactorily.
