摘要：

The basic shock signal should be evaluated for the shock design of naval ship components. The shock response spectrum specified in the standard norm usually cannot reflect the complex dynamic characteristics of the shock data recorded in ship shock tests. A curre fit method for naval underwater explosion shock signal was developed to get more approprite input load signal for anti-shock simulation and evaluation of naval equipments. Fourier transform was adopted to modify the measured signal curve for fitting in with the corresponding shock response spectrum in standard design. The corrected shock signal keeps both the real shock property and the shock magnitude of the standard design spectrum, which can more accurately represent the naval vessel shock environment at specification position under real underwater explosion shock excitation.
