Wrapping Deployment Simulation Analysis of Leaf-Inspired Membrane Structures

Deployable membrane structures have received wide attention in many engineering applications, such as the military, aerospace, and aviation. Their properties of light weight high storage ratio meet requirements for aerospace exactly. In this paper, wrapping deployment inspired by leaves are simulation-analyzed prospective improvement. Three leaf-inspired patterns investigated discussed from corresponding paper-craft design principles process perspectives. The performance evaluation system according to factors effecting working including maximum stress, driving force, strain energy, smoothness index, folding height is established based on results simulation analysis. Then, a comparison between three carried out system. Moreover, it found that adding creases reduces folded but development gets worse. There balance when additional added. can provide useful suggestions designing structures.
