| 摘 要： | 对混合有限元模型应用于船体振动分析的方法进行了讨论,并建立了某船的混合有限元模型,分别对其船体总振动和局部振动进行了计算.计算结果表明,混合有限元模型的总振动计算结果略小于迁移矩阵法,而局部振动计算结果与孤立模型存在较大差异.

| Abstract: | A method of analyzing the hull vibration by mixing finite element model is discussed. The mixing finite element model of a ship is established, and its inherent frequencies of overall vibration and local vibration are computed respectively. The computing result shows that the result of overall vibration computed by the mixing finite element model is appreciably less than that by matrix transfer method, whereas there is definite difference between the results of local vibration by the mixing finite element model and that by isolated model. |
