摘　　要：在营运过程中,船体本身具有一个固有频率。如果能准确知道它的固有频率,将对船舶设计有很大帮助。本文采用目前流行的有限元分析软件,计算分析某船体吊机舱的固有频率,分析结果对设备选型与布置安装有一定的指导意义。During the course of the operation, the ship hull itselt has a natural trequency. 1t we can exactly know the natural frequency, it will be of great help to ship design. This paper adopt the finite？ element？ analysis？ software which is popular at present to calculate and analysis the natural frequency of the ship hull, The results of analysis have a guiding value to the selection and the layout of the equipment.
