摘　　要：简要介绍了9 000 hp拖船总体振动的计算方法,并采用锚激发对船体的总振动进行试验研究。试验结果表明利用迁移矩阵法计算得到的压载出港条件下全船的振动结果与试验结果差距不大。With an outline of calculation method for the general vibration of a 9 000 hp tugboat, an experiment research is carried out by anchor excitation. Experiment results indicate that there isn＇ t much difference between experiment results and that of ship general vibration under ballast outbound condition calculated by transfer matrix method.

关 键 词：船体总振动 迁移矩阵法 模态分析
