| 摘 要： | 选取三维势流理论,使用SESAM软件计算大型自航绞吸挖泥船在规则波中六个自由度的运动响应,并根据线性系统的响应规律对甲板上浪和螺旋桨出水做了短期预报,在计算中考虑了短峰波和方向谱.为考察艏艉开槽对船舶耐波性能的影响,计算时选取了艏艉封口的船型作对比计算,计算结果表明艏艉开槽降低了船舶的耐波性能.

| Abstract: | In this text,the motion response of the large self-propelling cutter-suction dredger with 6 free degree is calculated by SESAM software based on 3D potential flow theory.Then the short term prediction about shipping green water and propeller emergence is made on the basis of linear system response theory,with the consideration of short crested-wave and directional spectrum.In the result analysis the main consideration is focused on the influence of the sea keeping performance of the cutter-suction dredger c... |
