複合材積層曲面板上に作用する点衝撃の位置および荷重履歴の同定

抄録

In a previous paper, the authors presented the identification method of locations and force histories of point impacts on laminated composite flat plates by using the measured values of acceleration. This paper deals with an attempt to extend the method so as to apply to identification of point impacts on laminated composite curved panels. Numerical identification results are obtained for the single point impact and double point impacts on cross-ply laminated composite curved panels. The validity of the identification method to laminated composite curved panels is verified by comparing the identification results with exact ones. In addition, when the number of point impacts is unknown, a method to decide the identification results is proposed. Several numerical examples are considered to ascertain the validity of the proposed method.
