稳态加速度模拟试验设备:离心机设计(15)

Steady state acceleration simulation test equipment-centrifuge design(Serial No.15)

文章分3篇10章详细介绍了稳态加速度模拟试验设备——离心机的设计。上篇对稳态加速度环境及其效应、试验方法和相关标准作了阐述;中篇(上)系统介绍国内外该类离心机发展的基本历程、概貌及典型离心机结构细节,并对其适当予以小结与点评;中篇(下)对离心机运动学进行基本理论分析,研究总体设计和部件设计问题,提出离心机设计原则及相应计算方法;下篇通过一个国家"七五"科技攻关项目的研制报告作为实例,提供读者进行具体设计时参考。文中,作者对多年累积的技术资料与实践心得进行了系统整理与归纳,力求梳理出一条研制稳态加速度模拟用离心机的设计思路与实用程序,使其兼具资料性、技术性与实用性。该文对相关领域的研究者和技术人员将有一定启发与助益,对其他类同设备设计也有某些触类旁通作用,对该专业有兴趣的读者也可作为参考读物。文章主要探讨的对象是中型、大型、特大型航空航天离心机,土工离心机和载人离心机。在第7章中介绍了离心机半径、功率、结构布置、实验室建设等总体设计问题。

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.
