摘要
针对长艏楼船型遭遇的艏砰击及艉砰击现象,采用一系列规则波下的分段模型试验测得典型剖面处的垂向弯矩响应,通过时域向频域的变换获取响应值的非线性砰击弯矩成分,综合分析艏艉砰击载荷下船体的垂向弯矩响应,以及浪向、波高、航速等参数对响应特性的影响。
Aiming at the stern-slamming and bow-slamming phenomenon of long forecastle ship form, the vertical bending moment response at typical sections were measured by sectional model tests under a series of regular waves. Nonlinear slamming moment components of response values were obtained by time-domain transformations. The vertical bending moment response under the stern and bow slamming load were analyzed integratedly. The effects of wave direction, wave height and ship speed on the response characteristics were also studied.
