The problem about ship collision is the hot point of the ship mechanics. However, the research work in the past always ignored the influence of the shapes of different striking bows. The quantitative comparison analysis was performed for striking with different bow curvatures and bow angles. The results show that different shapes of the striking bows have an obvious impact on the collision capability. The smaller of the striking bulb curvatures parameter or the bigger of the striking bow angles, the deeper of the limited penetration, the higher of the collision force, the more of the energy absorption at the limited penetration.
