The invention provides a trimaran falling body slamming test main body weakening model, belongs to the field of ship body structural strength, and particularly relates to a trimaran falling body slamming test main body weakening model. The problem that a test result is affected due to the fact that two peak values of a connecting bridge slamming pressure time-history curve obtained in an existingreal ship model falling body force test do not conform to the actual situation is solved. And the slamming load of the connecting bridge part under the condition that the main hull part does not discharge water can be studied in a more targeted manner. The ship model comprises a main ship body part, a connecting bridge part and a sheet body part, the molded lines of the connecting bridge part andthe sheet body part are the same as those of a real ship model, the size AB of the connecting bridge part is the same as the size EF of the connecting bridge part of the real ship model, and the height D of the main ship body part is larger than the height H of the main ship body part of the real ship model. The two sides of the main hull part are sequentially connected with the connecting bridgepart and the sheet body part to form a main body weakening model, and the main body weakening model is of an integrated structure. The model is mainly used for forecasting the slamming load of the connecting bridge in the falling body slamming test.

    本发明提出了一种三体船落体砰击试验主体弱化模型,属于船体结构强度领域,特别是涉及一种三体船落体砰击试验主体弱化模型。解决了现有实船模型落体抨击试验中得到的连接桥部砰击压力时历曲线存在两个峰值与实际情况不符,影响试验结果的问题。能够更有针对性的研究主船体部未出水情况下连接桥部的砰击载荷。它包括包括主船体部、连接桥部和片体部,所述连接桥部和片体部型线与实船模型相同,所述连接桥部的尺寸AB与实船模型连接桥部的尺寸EF相同,所述主船体部的高度D大于实船模型主船体部的高度H,所述主船体部两侧与连接桥部和片体部依次相连形成主体弱化模型,所述主体弱化模型为一体结构。它主要用于落体砰击试验中预报连接桥砰击载荷。
