Analysis of the Mechanical Properties and Study of Influential Factors of Different Materials in Tape Spring

This paper analyzes and calculates the mechanical properties of composite tape spring structures during folding bending establishes a non-linear control equation for laminate structures. Accurate expressions displacements are obtained. The influence cross-section’s central angle spring’s ply thickness on their analyzed. Finite element numerical analysis is performed [−45 45]s laminated springs, correctness theoretical derivation proved by comparing curvature radius-bending moment curve. Based previous research, different materials compared, further studying lightweight design space deployment mechanisms. results show that steady-state performance springs excellent, with 162.1% improvement in per unit mass compared to traditional metallic springs. Additionally, critical negative Poisson ratio honeycomb structure also 62.3%
