Identification Method and Experimental Verification of Longitudinal Bending Load of Hull Beam
Based on the dynamic response of structural strain,the theoretical model of total longitudinal bending load identification of ship hull beam was established by using time domain deconvolution algo-rithm.Combining Tikhonov regularization theory and FFT(Fast Fourier Transform)filtering algo-rithm,the accuracy of load identification was effectively improved.The validity of the theoretical model of load identification was verified by a series of dynamic load tests of box beam structure mod-els.The results show that the established theoretical model of load identification can accurately in-verse the time-history curve of applied load,and the error is less than 5％.
