Title Inflation Analysis for Pneumatic Membrane Structures with Air-Mole-Constraint
Author Ken'ichi Kawaguchi,Masahiko Kaneko
Summary Pneumatic membrane structures are usually assembled before the inflation. Then the air is blown into the inner space to give tensions tress to their thin surface skinsüEîwhich keeps the air pressure inside. Before this inflation process numerical simulation is usually required because the membrane and cable reinforcements experience large shape transformation during the inflation. HoweverüEîbecause of indeterminacy of the solving processüEîconventional load -control analysis can not be performed properly. Especially when the inner pressure balances with the dead load this problem is very crucial. In the Inflation process air-molecular-weight increases certainly. In the paperüEîfor pneumatic membrane structuresüEînew analytical procedure with mole-control is proposed. AndüEînumerical analysis for inextensional displacement using isoparametric membrane elements is reported.
