主　　题：spacecraft radiation heat calculation whole course numerical simulation 

摘      要：The surface radiation heat simulation program based on Microsoft VC++ 6.0 for spacecraft in whole orbit course was *** to complexity of spacecraft structure,the spacecraft structures were decomposed to relatively regular *** generation of calculation grid was conducted by using structured grid and unstructured *** mainly solved automatic grid generation for arbitrary surface and data transmission between arbitrary shape interfaces,and the geometry structure,physical process,calculation accuracy and efficiency were *** factors and radiation transfer coefficients were calculated by combining finite element method and ray uniform *** to the position of surface cells,external heat flux was calculated with integral method for non-shaded surface and with ray uniform distribution method for shaded *** the spacecraft surface was wrapped with multilayer insulation material,the temperature field of multilayer insulation material was calculated with nodal network method and finite volume *** temperature of other parts without wrap was calculated with finite element *** temperature of unconnected regions available with radiation heat transfer relations was analyzed,and the calculation formulae were *** experiment shows that the simulation program is correct and effective.
