The thermal control indicators CAE methods of Space optical remote sensor are analyzed in the presented work. We sat up a thermal optical analysis model for space optical remote sensor. By assuming fully covered by in-orbit temperature load
and using the finite element method for thermal deformation analysis
we obtained the optical remote sensor surface deformation and displacement under various thermal loading. Using ZERNIKE polynomial
wave was fitted to obtain ZERNIKE polynomial coefficients which were incorporated into the optical system design. Using CODE V optical calculation software
heat-ray machines under elastic deformation of the system point spread function
transfer function (MTF)
wave front differential (WFE) etc. were calculated. Image quality changes of remote sensors are discussed in variety assumed cases such as temperature loads of quality change. By repeated iteration
critical value of temperature fields meeting the design requirements are obtained for the optical system. Optical indicators were converged to the temperature field indicator
then reasonable indicators of thermal control for remote sensors were obtained. For the thermal control design
this method provided a reliable basis for design. (2011) Trans Tech Publications

On the analysis of the original data recorder
the stress wave theory is the elastic theory can explain the filter buffer question from the micro-small space
made several key problems clear when buffer and damping
from this designed a composite structure for vibration reduction
distinguished between a cushion theory and application field of stress wave theory
which made the dynamic stress of protected component down about one order of magnitude. Optimization with Isight and Ls-dyna
the traditional rigid spring-buffer model whose object is to reduce the impact of acceleration that can not accurately describe the elastic force of the part of the actual situation
the protected component's dynamic stress down about 69.3% and the data recorder's quality 300g lower
finally passed the Marshall Hammer test successfully. 2011 Trans Tech Publications.
