Abstract

In order to avoid the fatigue crack because of the stress concentration of the hyper-elastic boom and prolong its service life, the flattening finite element model for a triangular retractable and collapsible(TRAC)boom is established by the ABAQUS software, the S4R shell unit and the cohesive bonding unit. The explicit dynamic method is used to carry out the non-linear numerical simulation analysis for the flattening process of the TRAC boom, with single material, layering manners of two materials and TRAC boom stress characteristics for different layering angles compared, the layering method with the least stress is selected. This study is of great significance for the reasonable selection of the optimal lamination method for a TRAC boom in a deployable mechanism.
