Abstract
In this paper is examined a simple identification method of force locations and histories of point impacts on anisotropic composite laminated plates by using measured values of acceleration, in which the force locations are identified through an iteration procedure. The data processing method for improving the accuracy of identification is also examined when the measured values of acceleration contain measurement errors. To verify the validity of the identification method, the identification is performed for balanced laminated plates and cross-ply laminated plates using the measured values of acceleration without measurement errors. The identification results are compared with the exact ones and it is found that the acceptable identification results are obtained for not so much great number of measurement points. Finally, using the measured values of acceleration with measurement errors, the accuracy of identification by three different data processing is examined for balanced laminated plates. As the result, the best accuracy of the identification results is achieved for the data processing of running average.
