Abstract
This paper presents a practical method for load reconstruction on an advanced grid-stiffened (AGS) composite plate. With this method, separate AGS ribs are smeared onto a continuous unsymmetrical plate. A forward response approximate model is then built to describe the dynamic response of the plate. Numerical verification indicates that the proposed model can simulate the structure with reasonable accuracy and high computing speed. We also adopted an optimization technology to recover the load history and location. The load history is recovered with a smoothing/filter algorithm and the load location is estimated with a linear search for the lowest value of a defined figure of merit J, which measures the difference between the calculated response and the measured response. The feasibility of the reconstruction technology has been verified by numerical experiments in which good agreements were obtained. Since it calculates rapidly, it is possible to use the proposed method to develop an automatic system to monitor environmental conditions causing emergency in real time.
