摘要

摘要: 微重力燃烧实验柜安装在载人空间站内，其用途是为研究燃烧提供良好的微重力环境，因而对燃烧理论和模型发展、空天推进动力技术突破、空间防火安全设计等具有重要价值.多功能支撑平板是燃烧实验系统中固定各种光学诊断设备、燃烧室以及辅助类组件的关键支撑结构.在考虑重量和尺寸约束的条件下，平板需保证足够的刚度和安装空间.通过分体式结构设计，使平板在满足安装空间需求的同时能够顺利通过舱门；通过有限元模态分析及优化设计，使平板在满足重量约束的条件下具有足够的刚度.

Abstract: The microgravity Combustion Science Rack (CSR) in a manned space station can provide extended duration microgravity environment for combustion study. It thus has significant value for the development of combustion theories and models and the breakthrough of aerospace propulsion technology. In the CSR, the Multifunctional Supporting Bench (MSB) is a crucial structure because it is used to fix a variety of parts and units such as the combustion measuring devices, the combustor and the experimental control modules and so on. The MSB must have enough stiffness and installation space in view of the constraints of size and mass. In this paper, a split-body structure is designed to make the MSB smoothly pass through the hatch. According to the finite element method, structural optimization design as well as modal analysis is employed to satisfy the stiffness requirement without overweight.
