| 摘 要： | 针对有限元程序在隐式分析方面不能解决大规模计算的弊端,提出用显式分析法对现有计算方法进行改进.研究表明,显式分析法能有效改善因计算规模带来的问题,并能更直观地反映结构的实际振动情况.在此基础上,计及螺旋桨脉动压力与轴承力的影响,针对某舰不同航行状态开展了螺旋桨激励力对舰船振动的影响研究,得到了不同航行状态下舰船的振动响应,分析结果表明:同一航速下,双桨同时工作较四桨同时工作的振动偏大,从减小振动角度出发,宜采用四桨同时推进的方式航行.

| Abstract: | Based on theoretical analysis,explicit analysis method is introduced as an amends to harmonic analysis for large scale calculation problems which cannot be solved with implicit analysis method due to the shortage of memory.The study shows that explicit analysis method can smooth the defects of calculation scale caused by implicit analysis.And explicit analysis method can show more details intuitively of real structures.Considering influence of pulsating force of propellers and bearings,the study on the infl... |
