摘要
用三维模型的有限元法计算得出了某船垂向总振动的各阶固有频率和振型．并在试验室进行了实船干模态的振动特性模拟试验。结果表明：三维有限元法能够精确地反映船舶结构的振动特性．计算结果与试验结果有很好的一致性。
The inherent frequencies and modes of vertical vibration of some ship are calculated by usingthe three dimensional finite element method. Then a laboratorial ted was designed with a model to imitated the vibration characteristics of the real ship in the air. The results show that the three dimensionalfinite element method is accurate in analysing the vibration of the ship body,and the coincidence between the tested results and calculated ones is quite good.
