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％.
