【摘要】：為縮短旋轉(zhuǎn)整體式斯特林制冷機的研發(fā)周期、提高設(shè)計效率及降低開發(fā)成本,提出了一種基于計算機輔助設(shè)計的旋轉(zhuǎn)整體式斯特林制冷機動力學(xué)設(shè)計方法。根據(jù)外形尺寸、輸入功率及振動輸出等已知參數(shù),重點從旋轉(zhuǎn)電機、軸承選型、飛輪設(shè)計及曲柄連桿機構(gòu)強度校核4個方面采用計算機輔助設(shè)計方式進行動力學(xué)設(shè)計研究。通過三維設(shè)計軟件Pro/E對制冷機組件建模后導(dǎo)入Adams虛擬樣機進行動力學(xué)仿真分析,將仿真分析結(jié)果導(dǎo)入Ansys有限元軟件進行制冷機組件強度校核。通過該方法設(shè)計出的制冷機實測制冷量為1.65 W@80 K/23℃,比目標值提高27%,振動輸出為0.3N,比目標值降低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，
