空间薄膜结构展开分析模型研究综述

随着空间薄膜结构的快速发展,如何有效地实现空间薄膜结构的展开变得越来越重要,已成为航天工程所关注的关键技术问题之一.空间薄膜结构如果不能可靠展开,将会直接影响到与之相连的航天器的表面精度、信号发射等工作性能,对于航天器是否能完成预定的航天任务具有非常重要的意义.本文通过对国际上目前采用的常见空间薄膜结构的展开分析理论和实验模型进行综述,特别是对流—固耦合模型、弹簧—质点模型、控制体积模型和能量—动量模型等几种主要分析模型从理论依据、实践应用以及优缺点等方面进行了比较分析,提出了相应的修正建议,为进一步进行空间薄膜结构的展开分析具有重要的理论指导和实践借鉴意义.

Study on Analysis Model of Deployable Space Membrane Structure

With the rapid development of space membrane structures,how to effectively implement the deployment of space membrane structures have become more and more important and one of the key technical issues of concern to aerospace engineering.If the space membrane structure cannot be reliably deployed,it will directly affect the performance of the spacecraft such as accuracy,signal transmission,etc.,and for the spacecraft to complete the space mission as expected has very important significance.In this paper,several international theoretical and experimental analysis models of deployment of common space membrane structures were reviewed,particularly comparative analysis of several major models such as fluent-solid coupling model,spring-mass model,control volume model and energy-momentum model,were conducted from the theoretical base,practical applications,and advantages and disadvantages of other aspects.Some proposed amendments to the corresponding recommendations for further space to analyze membrane structure has important theoretical and practical reference guide.
