Since the slamming load could cause severe damage of wet deck of ship hull girder, the interaction between the structural response and hydrodynamic loading should be considered. A large scaled model of trimaran was designed, which could consider the structural elastic for studying the structural response of trimaran hull girder. The testing model was vertically dropped into still water in the tank to simulate typical hydroelastic slamming load, in which various impact velocities were considered. Each load condition was conducted several times to verify the repeatability and reproducibility of the experimental data. The slamming pressure and strain distributions are presented and discussed. The ranges of maximum slamming pressure and the danger area are identified for design of this type of trimaran.

由于砰击载荷会对船体梁湿甲板造成严重破坏，因此应考虑结构响应与水动力载荷之间的相互作用。设计了考虑结构弹性的大比例三体船模型，用于研究三体船船体梁的结构响应。将测试模型垂直落入水箱中的静水中，模拟典型的水弹性砰击载荷，其中考虑了各种冲击速度。每个负载条件进行多次，以验证实验数据的重复性和再现性。提出并讨论了砰击压力和应变分布。此类三体船的设计确定了最大砰击压力范围和危险区域。
