Abstract

© 2022, Editorial Office of Journal of Vibration and Shock. All right reserved. With increase in number of ships sailing on sea, the probability of ship collision accident also increases gradually. A bulbous bow is a common design form of ships. Currently, studies on head-on ship collision scenarios are more than those on oblique ship collision scenarios. However, statistical data show that the probability of oblique ship collision is higher than that of head-on ship collision. Here, studying oblique ship collision was performed when a bulbous bow obliquely impacting a ship side structure. The theoretical deformation models of the side shell plating, the web girder and the transverse frame according with characteristics of bulbous bow obliquely impacting ship side structure were established, and analytical calculation formulas for deformation resistances of these 3 components in oblique collision process were derived by using the plastic mechanics theory. In addition, the finite element software LS_DYNA was used for numerical simulation to verify the correctness of analytical calculation results. It was shown that the study results have better engineering application value for evaluating the crashworthiness of ship side structure.
