Аннотация

This paper presents the buckling analysis of a new large-sized umbrella space reflector and its framework spoke members via finite element method. The main goal is to obtain critical load values for the reflector and its framework spoke members with corresponding buckling modes. In the context of considered method, linear and nonlinear approaches are used. To verify the linear analysis results for spoke the dynamic buckling analysis was applied, including the spoke first natural frequency decreasing under increasing axial loads. In the case of buckling this frequency equals zero. Additionally, according to reflector buckling analysis, it was proved that the safety factor for reflector framework structure is more than eight. Thus, this structure could be considered as reliable in view of buckling.
