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.
