| 摘 要： | 对三体船总振动预报,需计算参与振动的附连水质量。采用ANSYS流固耦合方法模拟了一系列的不同尺度比、不同间距的三圆柱在水中振动特性,并计算附连水质量。三圆柱体的振动附连水质量随着片体增大而增加,垂向附连水质量随着片体与主体的间距增大而减小,水平振动附连水则相反,但最终都趋向于3个单独的圆柱体附连水质量之和,并根据所求结果在单圆柱体的基础上给出一个修正系数来求三圆柱体的附连水质量,并推广到三体船上。

| Abstract: | A global vibration prediction of the trimaran needs the correct calculation of the added water mass involved in vibration.ANSYS was used to solve this problem by the method of fluid-solid coupling vibration.A series of different scale and the distance between the side body and main body were simulated,and calculated the added water mass.In accordance with the results of the request a correction factor to calculate the added water mass of ternate-cylinders is given on the basis of a single-ylinder,and extended to trimaran,which provides foundation to calculate the added water mass of ternate-cylinders for wet-mode. |
