Modeling Research on the Optical Characteristics of Membrane Object Inflating

Abstract

With the internal pressure is bigger than the external, the folded membrane object gradually inflate and form into the ball, column, cone and other original shapes. In the inflating process, the optical characteristics of the object changes obviously. Combined with finite element analysis method, the geometry is divided into a plurality of surface element. Analyze the stress of different surface elements, establish the force balance equation of different elements, research on the motion of element in the expansion, form the geometry parametric inflating model. On the basis of the model, the time dependent optical characteristics of the geometry in the inflating process are studied.
