抄録

In this paper we propose a simple method for identification of multiple impact forces on a simply supported orthotropic laminated plate. Acceleration responses at several points in the interior of the plate are measured in order to determine locations and histories of the impact forces. The present method can identify the impact forces at any arbitrary locations of the plate with every measurement of acceleration. First, the identification algorithm is shown for single and double impact forces at arbitrary locations on the plate. Next, through the numerical examples we examine the effect of the number of measurement points on the identified results and the measurement errors are also taken into consideration in the identification. The validity of the present method is shown by comparing the present results with exact ones for locations and histories of impact forces.
