    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.
