Abstract
During its lifetime, a satellite undergoes harsh conditions ranging from takeoff-induced vibrations to wide gradients of temperature while in orbit. To design a satellite to withstand these conditions, computer simulations and experiments have to be carried out. This study focuses on the modelling of certain components of the hard X-ray imager smallsat HSP : the thermal modelling of a CZT crystal array, the thermomechanical modelling of a coded aperture mask and the vibration analysis of a coded aperture mask. To perform X-ray radiation experiments, two thermal vacuum chambers are needed. Their design have been achieved through computer modelling and their assembly has begun. The preliminary models show the current design for HSP is suitable to maintain thermal control, and avoid detrimental mask deformation during takeoff and while in orbit. However, additional more detailed simulations and experiments are to be conducted to further prove the suitability of the satellite's design.
