多闭环厚板折展蜂窝机构的几何设计与性能分析
Geometric Design and Performance Analysis of Multi-closed-loop Deployable Honeycomb Mechanisms with Thick Panels
摘要
Abstract
A new type of space mechanisms with single-closed-loop was proposed according to thick-panel origami teory,and the mobility was analyzed by using screw theory.The degree of free-dom of mechanism was reduced to 1 by the introduction of Myard constraint and Sarrus constraint,and the corresponding deployable units were obtained with the names of Myard deployable honeycomb unit and Sarrus deployable honeycomb unit.M-type honeycomb mechanism and S-type honeycomb mechanism were proposed based on kinematic analysis and planar mosaic array of deployable honey-comb units.The influence regularity of various factors on folding ratio was analyzed,and the deploy-able honeycomb units were optimized with the rising of folding ratio index.The results show that M-type honeycomb mechanism may achieve flat surface,and S-type honeycomb mechanism may achieve higher folding ratio index.关键词
