Identification of Load Vector and Its Location using the Cuckoo Optimization Method

To ensure the safety and reliability of a structure, it is necessary to accurately grasp the magnitude and location of the load acting on it. In this study, we proposed a method to identify the load vector and its acting location using the cuckoo optimization method. In the proposed method, the rotation angle measured by a wireless gyro sensor was related with the load vector via a matrix equation. Then, the location where the load acts was estimated using the cuckoo optimization method, and the magnitude of the load was then estimated using a generalized inverse matrix. In order to verify the effectiveness of the load identification method proposed in this study, we attempted to identify the magnitude and location of the acting load for the problem of a beam with fixed ends on which a concentrated load acts, and the problem of a plate with supported ends on which a concentrated load acts. As a result, it was confirmed that the proposed method was able to estimate the magnitude and location of the acting load with high accuracy in both problems.
