穩(wěn)態(tài)加速度模擬試驗(yàn)設(shè)備:離心機(jī)設(shè)計(16)

Steady state acceleration simulation test equipment: centrifuge design (Part 16)

  • 摘要: 文章分3篇10章詳細(xì)介紹了穩(wěn)態(tài)加速度模擬試驗(yàn)設(shè)備——離心機(jī)的設(shè)計。上篇對穩(wěn)態(tài)加速度環(huán)境及其效應(yīng)、試驗(yàn)方法和相關(guān)標(biāo)準(zhǔn)作了闡述;中篇(上)系統(tǒng)介紹國內(nèi)外該類離心機(jī)發(fā)展的基本歷程、概貌及典型離心機(jī)結(jié)構(gòu)細(xì)節(jié),并對其適當(dāng)予以小結(jié)與點(diǎn)評;中篇(下)對離心機(jī)運(yùn)動學(xué)進(jìn)行基本理論分析,研究總體設(shè)計和部件設(shè)計問題,提出離心機(jī)設(shè)計原則及相應(yīng)計算方法;下篇通過一個國家“七五”科技攻關(guān)項(xiàng)目的研制報告作為實(shí)例,提供讀者進(jìn)行具體設(shè)計時參考。文中,作者對多年累積的技術(shù)資料與實(shí)踐心得進(jìn)行了系統(tǒng)整理與歸納,力求梳理出一條研制穩(wěn)態(tài)加速度模擬用離心機(jī)的設(shè)計思路與實(shí)用程序,使其兼具資料性、技術(shù)性與實(shí)用性。該文對相關(guān)領(lǐng)域的研究者和技術(shù)人員將有一定啟發(fā)與助益,對其他類同設(shè)備設(shè)計也有某些觸類旁通作用,對該專業(yè)有興趣的讀者也可作為參考讀物。文章主要探討的對象是中型、大型、特大型航空航天離心機(jī),土工離心機(jī)和載人離心機(jī)。在第7章中介紹了離心機(jī)半徑、功率、結(jié)構(gòu)布置、實(shí)驗(yàn)室建設(shè)等總體設(shè)計問題。

     

    Abstract: This paper is divided into three parts, altogether ten chapters, to discuss the non-standard steady state acceleration simulation test equipment-centrifuge-in detail. The first part discusses the steady state acceleration environment and its effect, the correlation testing methods and the national standards. The second partⅠdiscusses the domestic and foreign centrifuge developments and the structures with a brief history and provides a more comprehensive structure survey for all kinds of centrifuges. The second partⅡpresents the elementary theoretical analysis, the research general layout design and the components design, the principles of design and the computational method. The third part provides a practical design example. The main concern of this paper is the medium, large-scale, and extra-large type aerospace centrifuges, the geotechnical centrifuges and the human centrifuges. The seventh chapter discusses overall design issues about centrifuge, including radius, power, structural arrangement, laboratory setup, and others.
