- J191013 On Uncertainty Estimation of Structural Parameters Using Bootstrap Method
抄録
Design of a very precise space structural system requires an accurate estimation of uncertainties on structural and environmental parameters. For the purpose, high accurate estimations of uncertainties of the structural parameters and the effect of the paremeter uncertainties on the structural response uncertainty are required. Then, the robust design optimization based on the accurate estaimation is required. This study focuses on the former part, a high accurate estimation of the uncertainties. The applicability of a bootstrap method known as a nonparametric technique is investigated to estimate the confidence intervals of the uncertain parameters related to vibration responses of simple structures. The target structure is a cantileverd bow-shaped structure composed of beam and tether that is a breadboard model of a lightweight space reflector. The confidence intervals identified from several numbers of vibration tests is compared by the nonlinear finite-element analysis.
