Abstract: The slamming phenomenon is ruinous to the bow structure of ships and is a grave threat to the safety of crew members， especially when ships are at middle and high speeds. Due to its inherent transient and strong non-linear property， the accurate simulation of the slamming process has been quite unsuccessful， and the response of the bow structure to the slamming has been rarely investigated. Therefore， this paper aims at calculating the slamming loads that varies with space and time by incorporating the maximum slamming load value under the design wave and the exact value of the slamming loads collected in former experiments. The transient response is then calculated by using the central difference method after the slamming loads impact the bow structure. Particularly， the time interval and a few key parameters for solving the problem are presented. The results show that the stress on different elements can be obtained accurately， which could be further used as references during the bow structure design.
