【摘要】：為縮短旋轉(zhuǎn)整體式斯特林制冷機(jī)的研發(fā)周期、提高設(shè)計(jì)效率及降低開發(fā)成本,提出了一種基于計(jì)算機(jī)輔助設(shè)計(jì)的旋轉(zhuǎn)整體式斯特林制冷機(jī)動(dòng)力學(xué)設(shè)計(jì)方法。根據(jù)外形尺寸、輸入功率及振動(dòng)輸出等已知參數(shù),重點(diǎn)從旋轉(zhuǎn)電機(jī)、軸承選型、飛輪設(shè)計(jì)及曲柄連桿機(jī)構(gòu)強(qiáng)度校核4個(gè)方面采用計(jì)算機(jī)輔助設(shè)計(jì)方式進(jìn)行動(dòng)力學(xué)設(shè)計(jì)研究。通過(guò)三維設(shè)計(jì)軟件Pro/E對(duì)制冷機(jī)組件建模后導(dǎo)入Adams虛擬樣機(jī)進(jìn)行動(dòng)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(jìn)行制冷機(jī)組件強(qiáng)度校核。通過(guò)該方法設(shè)計(jì)出的制冷機(jī)實(shí)測(cè)制冷量為1.65 W@80 K/23℃,比目標(biāo)值提高27%,振動(dòng)輸出為0.3N,比目標(biāo)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，
