【摘要】：为缩短旋转整体式斯特林制冷机的研发周期、提高设计效率及降低开发成本,提出了一种基于计算机辅助设计的旋转整体式斯特林制冷机动力学设计方法。根据外形尺寸、输入功率及振动输出等已知参数,重点从旋转电机、轴承选型、飞轮设计及曲柄连杆机构强度校核4个方面采用计算机辅助设计方式进行动力学设计研究。通过三维设计软件Pro/E对制冷机组件建模后导入Adams虚拟样机进行动力学仿真分析,将仿真分析结果导入Ansys有限元软件进行制冷机组件强度校核。通过该方法设计出的制冷机实测制冷量为1.65 W@80 K/23℃,比目标值提高27%,振动输出为0.3N,比目标值降低25%。
[Abstract]:In order to shorten the research and development period of the rotary integral Stirling refrigerator, improve the design efficiency and reduce the development cost, a dynamic design method of the rotary integral Stirling refrigerator based on computer aided design is proposed. Input power, vibration output and other known parameters, especially from rotary motor, bearing selection, Four aspects of flywheel design and strength checking of crank and connecting rod mechanism are studied by means of computer aided design (CAD). The dynamic simulation analysis is carried out by introducing Adams virtual prototype into the model of refrigeration unit by using 3D design software Pro/E. The results of simulation analysis are introduced into Ansys finite element software to check the strength of the refrigerating units. The measured refrigerating capacity of the refrigerator designed by this method is 1.65 W @ @ 80K / 23 鈩，
