摘　　要：以某船舶改装项目为例,采用迁移矩阵法对船舶在满载和空载状态下的总振动固有频率和振型进行计算分析。对改装后的船体总振动固有频率进行预报,为船舶改装结构设计和设备避振提供工程指导。采用的计算方法可为船舶总振动固有频率和振型的预报分析提供借鉴。The transfer matrix method is used to calculate and analyze the global vibration frequencies and vibration modes of a refit ship under both full load and ballasted conditions.The global vibration natural frequencies of the refitted ship are predicted to produce engineering guidance for the structural refit design and the anti-vibration measures of equipment.The adopted calculation method is expected to provide reference for the prediction and analysis of ship's global vibration frequencies and vibration modes.

关 键 词：迁移矩阵法 自由振动计算 强迫振动计算 总振动固有频率
