摘要：A comparative collision study of a conventional bulbous bow and a sharp entrance angle bow structure was conducted using elasto-plastic finite element analysis to demonstrate the superior collision buffer bow characteristics of the sharp entrance angle bow structure. Further improvements that optimize the design and energy absorption of the sharp entrance angle bow structure by replacing the longitudinal stiffened steel panels of outer shells with hybrid structures composed of polyurethane elastomer cores and steel faceplates were proposed. In addition, the stem structure replaced with the hybrid structure with a polyurethane foam core was also proposed. The new structures eliminate the number of framing members to simplify construction to enhance the collision buffer characteristic of the present conventional structure.
