Bow bottom slamming of ship is one of the physical phenomena, which often appears during heavy sea conditions
船首底部砰擊是船舶在嚴重海況中航行時經常發生的一種物理現象。 -
Since kamen and vagena, many researchers have discussed it in theory and experiment method. the main content in this paper is to set forth the slamming press calculations in dnv rules, gl rules and lr rules and the requirements for slamming strengthened bow structure and some comparisons ; slamming strengthened bow structure design for a bulk is carried out using dnv rules, and comparisons among several design schemes is carried through when heavy loading draft status replaces light loading draft status in practice. the results from above have been applied in ship production ; it is significant for ship structure improvement latter to calculate slamming press with direct calculation method, and then to design bow structure with dnv rules
本文的主要內容是分別闡述dnv 、 gl 、 lr三種規范對底部砰擊壓力計算及底部砰擊加強結構設計的一般要求並進行一些分析比較：用dnv規范對某型船（ 27000t散貨船）進行具體的底部砰擊加強結構設計，並就實際生產中產生的重載吃水狀態改輕載吃水狀態而出現的幾種設計方案進行比較，其具體結果現已用於實際生產；用直接計演算法確定砰擊壓力，再用dnv規范進行底部結構設計，對於後續船的改進均有指導意義。
