摘要 介绍了自由活塞斯特林制冷机用动磁式直线电机结构。采用Ansoft软件对直线电机进行有限元仿真,配合自由活塞制冷机整机仿真软件,研究了直线电机性能及整机制冷性能。采用三组不同外气隙参数的直线电机进行试验验证,结果表明:直线电机性能对整机性能影响较大,且直线电机的定位力会影响动子系统的固有频率,降低自由活塞制冷机的制冷效率;外气隙参数对直线电机性能影响较大,经比较:0.5 mm为外气隙优选参数,并且,在生产过程中须保证直线电机的径向加工精度。 The structure of linear motor for free-piston Stirling cooler is introduced.FEM simulation was carried out on the linear motor with the Ansoft software,and matching with the simulation software for whole free-piston cooler,the performance of linear motor and whole cooler were studied.Test verification was carried out on three linear motors with different outer air gaps,and it showed that the linear motors have big effect on the whole cooler,and the motor's mass may influence the natural frequency of the rotor system,and reduce the cooling efficiency of the free-piston cooler.The outer air gap had a bigger influence on the linear motor,and 0.5mm was proved to be the optimal parameter by comparison.During the manufacturing,the machining accuracy of the radical direction must be maintained at a reasonable level.
