摘　　要：考虑到国际海事组织(IMO)、船旗国,以及船东对振动的要求的日益提高,常用的振动标准已被更加严苛的标准所取代,有必要在详细设计阶段,对船舶的总体和局部振动进行预报,以避免未来发生振动问题引起不必要的费用增加,避开船东弃船的风险,利用PATRAN计算软件,建立振动仿真模型,基于固有频率法和响应法,对船体的总体振动和局部区域振动进行预报,结果表明,支线集装箱船总体振动和局部区域振动同时满足新的和旧的标准。The demand in vibration has been enhanced increasingly from IMO,flag state and ship owner,the common vibration criteria has been replaced by more stringent standard,and it is necessary to predict the overall and local vibrations in the ship detail design stage,to avoid the future unnecessary cost from vibration problems and the risk of abandoned ship from ship owner.The overall and local vibration was predicted based on natural frequency and response method,by using PATRAN software.The prediction results showed that the overall and local vibrations of feeder container ship conform to both the new and old standards.
