S1903-2-1 ヒステリシスを考慮したケーブルネットワーク構造の形状再現性評価(宇宙構造・材料(2),社会変革を技術で廻す機械工学)
詳細
Shape repeatability of a cable-network structure with hysteresis is studied. An experimental model is built and some repetitious loads are applied on the model. Shapes of the experimental model are measured and changes in the shapes caused by the hysteresis and the material nonlinearities are quantified. Characteristics of cables are modeled and some numerical simulations are carried out. The experimental results are compared with the numerical simulations to investigate effects of hysteresis and material nonlinearities.
