矩形複合材積層板上に作用する点衝撃の位置および荷重履歴の同定に関する実験的検証 Experimental Verification of Identification of Location and Force History of a Point Impact on Rectangular Composite Laminated Plates
Experimental verification of identification of location and force history of a point impact on rectangular composite laminated plates is made in order to establish the identification method proposed previously. In experiments, a point impact on a rectangular composite laminated plate supported at one side was produced by an impulse hammer and the acceleration at points on the surface of the plate was measured by small accelerometers attached on the plate. It is found that by choosing appropriately the number of vibration modes in the identification method, the identification results of the location and force history of the point impact are in good agreement with the exact ones. This may imply that the possibilities of the practical application of the identification method can be expected.
