光ファイバーを用いたワイヤーロープの機械的特性の計測

抄録

In this paper, the measurement and calculation method of mechanical properties (Young's modulus and Poisson's ratio) of the wire rope using the optical fiber is shown. The optical fiber is stuck on the wire rope both spirally along the groove and to the axial direction. The helical strain along the groove and the axial strain of the wire rope are measured and substituted for the equation to calculate the average Young's modulus and Poisson's ratio. The Young's modulus of the wire rope is about one third of the ordinary steel one and the Poisson's ratio of the wire rope is more than ten times of the ordinary steel one.
