| 摘 要： | 小水线面双体船是一种耐波性较好的双体船,其水线面较小,但湿表面较大,使得附加质量对船体的振动特性影响较大。运用三维水弹性分析方法,以干模态为主坐标,分析小水线面双体船的振动特性。综合考虑波浪中附加质量的影响,得到小水线双体船的各阶主要总振型。同时,对实船进行了总体振型测试,得到相应的振型。计算与试验的结果对比分析显示,它们在该船的各主要振型模态上较为吻合,振型频率也一致,说明测试方法合理,数值计算方法可行。

| Abstract: | Small water plane area twin-hull ship(SWATH) is a new type catamaran with better sea keeping performance.Its water plane is smaller,but its wet hull surface area is greater than that of the normal ship,which leads to great effect on the vibration of the hull.Vibration response of SWATH hull is analyzed based on the 3D hydroelasticity method.Mode shapes of the dry hull are adopted as the principle coordinate,and the wave's influence is considered.Then the main overall vibration shapes of SWATH are achieved.M... |
