摘要
为获得船舶动力学响应,以船舶中典型的铰链接头结构为研究对象,根据板壳有限元理论,建立其有限元模型,并将其与惯性释放计算理论相耦合,对船舶铰链结构动力学特性进行计算。计算结果表明,在忽略结构复杂的边界条件情况下,仍能够通过惯性释放技术有效地获得结构动力特性,该方法能够为船舶工程力学设计提供参考。
In order to obtain the ship dynamic response,a typical hinge joints in ship structure is regarded as the research object,according to the theory of plate and shell finite element,the finite element model is established,then it is coupled with the inertial releory. Based on this,the hinge of the ship structure dynamic characteristics is calculated. The results show that when ignoring complex boundary conditions,the structure dynamic characteristics still can be obtained with efficiency through the inertial release technology. the method can provide reference for Marine engineering mechanics design.
