周期変動横荷重をうける偏平アーチの非線形振動 : 第2報,実験

抄録

Detailed experimental results have been obtained for the non-linear vibration response of a clamped shallow arch under uniformly distributed periodic lateral forces. An aluminum alloy test specimen with thickness 0.5 mm, breadth 30 mm, length 180 mm and radius of curvature 5619 mm was used and tests were conducted by shaking the base frame with a constant amplitude of acceleration and measuring the relative displacement of the arch to the frame. It is found that experimental results are good agreement with the theoretjcal ones. Besides the results for comparison with theoretical results, various non-linear responses were observed in connection with the super-sub harmonic resonance and dynamic snap-through phenomena.
