| Abstract: |
| This article proposed the circular or the side tube lattice piece power-absorbing element, and attracts based on the thin walled tube can the mechanism and the theory, has established the thin-wall construction lattice piece axial compression load theoretical model.In order to confirm the theoretical model the accuracy, this article uses Hypermesh and the LS-dyna finite element software carries on the simulation analysis to the lattice piece power-absorbing element, finally indicated the simulation analysis result and theoretical calculation result goodness of fit was high, has confirmed the theoretical model accuracy.Through the simulation analysis research discovery under the homogeneous condition, the side tube lattice piece stability and attracts can ability all surpass the circular lattice piece, has provided the new mentality and the theory support for the orbital transportation power-absorbing element design. #$NL Keyword: Lattice piece power-absorbing element; Axial compression; Thin-wall construction; Simulation analysis |
