Simulation and Analysis of Structural Dynamic Characteristics of Large Thermal Shields of the Space Telescope

The characterization of dynamic performance and dynamic response of the unfolded thermal shield structure in response to operational loads in the space environment is very important when developing large deployable thermal shields for future space telescopes. The authors of the article study this problem through additional approximations that allow them to use traditional modelling techniques for nonlinear analysis of transient dynamic processes. Simulation models based on two different approaches to the formulation and solution of motion equations for elastic body systems are developed. The simulation results are compared.
