前言 应用离心机分离铀是目前技术先进国家都在使用的方法,由于离心机分离功的大小随线速度的增加而大大增加,所以,尽力提高线速度是离心机转子设计中追求的主要目标。鉴于复合材料具有较高的比强度和比刚度,而且材料的力学性能可根据实际需要进行调整,从而使它成为制造离心机转子的理想材料。在这个基础上,对转子的结构形式、所选材料的种类和结构的铺层设计等方面提出了一系列要求,这些要求都与转子的动力分析有密切关系,亦即关系到复合材料转子的振动和稳定。关于普通材料转子的动力分析问题,已有相当成熟的研究结果,仅在80—82年,就有近200篇文章和报告从不同角度讨论了转子的稳定问题;但是由于复合材料离心机转子在结构形式、运行状态与构造材料方面所具有的特殊性,我们必须着重研究以下问题。 Introduction Uranium separation by centrifuge is a method used by most technologically advanced countries. Since the size of centrifuge separation work increases greatly with the increase of linear speed, trying to improve the linear velocity is the main goal of centrifuge rotor design. In view of the high specific strength and specific stiffness of the composite material, the mechanical properties of the material can be adjusted according to actual needs, making it an ideal material for making centrifuge rotors. On this basis, a series of requirements are put forward on the structure of the rotor, the type of material selected and the ply design of the structure. These requirements are closely related to the dynamic analysis of the rotor, that is, to the rotor of the composite material Vibration and stability. There are quite a few mature research results on the dynamic analysis of common material rotor. In the past 80-82, nearly 200 articles and reports discussed the rotor stability problems from different perspectives. However, since the rotor of the composite material centrifuge Structural form, operating status and construction materials have the particularity, we must focus on the following questions.
