摘要
为了提出一种有效且简易的线性压缩机设计和优化方案,本文针对一款商用Cryo S 100小型斯特林制冷机,推导出其动磁式线性压缩机中气体阻尼力和气体弹簧力的表达式,并采用COMSOL软件将压缩机动力模型和电磁模型相耦合,建立了联合仿真模型,模拟了不同负载下压缩机的动力特性,模拟结果与SAGE相吻合。通过空载下对线性压缩机的瞬态位移特性的测试和稳态下对电机比推力特性的测试,验证了耦合模型的准确性。
Based on the purpose of producing a brief and efficient scheme for design of linear compressors,we obtained an expression of gas damping force and gas elastic force in the moving-magnet linear compressor.Then a couple model,which combined pneumatic model with electromagnetic model,was built in COMSOL with a commercial smallscale Stirling Cryocooler prototype.The dynamic properties under different load condition were simulated and the result agreed well with the result in SAGE.Then the tests of specific thrust property and displacement of piston in different conditions were carried out to validate the model.
