摘要：
Here, to realize fast prediction of anti-collision capability of ship stiffened panel structure, an analytical prediction method for the crashworthiness of ship stiffened panel structure under bulbous bow impact to have large deformation and fracture was proposed. Aiming at large deformation process, theoretical deformation modes for panel and its attached reinforcement were proposed. Based on the relevant theory of plastic mechanics, calculation formulas for deformation resistance forces of panel and reinforcement were obtained. Aiming at initial fracture, the critical impact depth calculation formula of panel was proposed. Considering interaction between reinforcement and panel, the calculation formula for effects of reinforcement on panel critical impact depth was deduced. Finally, the calculation method for ship stiffened panel's critical impact depth was established. The correctness of the proposed analytical prediction formulas was verified with model tests. It was shown that the study results make a certain contribution to accurate and rapid evaluation of the crashworthiness of ship stiffened panels. © 2021, Editorial Office of Journal of Vibration and Shock.
