摘要
晃荡现象是海洋工程和船舶设计中值得关注的问题。它涉及到自由液面大幅度运动的一系列非线性问题 ,很难获得一个完全的理论解。相应的试验是主要方法。本文介绍三个自由度的模拟装置 ,并运用 MSC/ NASTRAN软件对该装置进行了结构有限元分析 ,重点在于模态分析。
WT5”BZ]The sloshing phenomena are of practical importance in ocean engineering and ship design. On account of the high non linearity related to the large amplitude motion of free liquid surface, it is very difficult to obtain a complete theoretical solution. Therefore the corresponding experiments are of great importance. A sloshing simulator device with three freedoms is designed and manufactured by School of Naval Architecture and Ocean Engineering of Shanghai Jiaotong University. It will play a prominent role in further studies. The present report gives a brief description of the structural FEM analysis with MSC/NASTRAN code for the simulator device, with the focus laid on the modal analysis.
