摘要
在波浪中航行的船舶不仅受到波浪激励,还受到船上机械设备的激励力作用。在分析船舶结构时,要全面分析设备开启时的激励力特性。论文运用三维船舶水弹性力学分析方法,利用设备基座的机械阻抗和设备开启时的实测加速度,可以较为精确地分析船上设备的等效激励力。
The exciting forces acted on the ship traveling in wave are not only from the wave, but also from the machines. In order to analyze the hull vibration, characteristics of the exciting forces from the working machines should be studied firstly. The paper introduces an analysis method. By 3D hydroelasticity method, equivalent exciting force of the machine on the ship can be accurately evaluated according to both the mechanical impedance of the bases of the machines and the tested acceleration data of the machines in working state.
