Modal analysis of inflatable shield for space debris

Abstract:

According to the essential characteristic of mechanical shields,a new inflatable shield was developed to settle the disadvantage of the existed shields,and its dynamic character was studied.The modal analysis of the inflatable shield was carried out by ANSYS.Factors affecting the inflatable structures were analyzed according to the theory of structural dynamics,and the principle of effects of structural dimension parameters on the modes of the configuration was obtained.It is found that the theoretical analysis agrees well with simulated results,and thickness and diameter of the inflatable pipe are main factors affecting the modes of the configuration of inflatable shield.
