Establishment of antenna membrane states FEM on analogue method
Establishment of antenna membrane states FEM on analogue method
摘要
Abstract
On the basis of choosing the basic element as the bar and choosing the basic mesh as the triangle as well as supposing the conditions of the element,the membrane states of an antenna reflector were researched by the analogue method,because the membrane effect Was not omitted during the ending deployment process of the radial rib antenna.The expressions of the bar element's section area and density were obtained.while the expression of the stress state during the ending deployment process of antenna was attained.During the establishment process of the analogue method,the analysis method of the net shell structure was employed.Moreover,during the backward deduction of membrane stress,the continuation method Was adopted.Because the expression of the membrane stress state can realize the analysis on the antenna membrane state.this research has great significance of theoretical direction to the normal operation of the space deployable antenna.关键词
