摘要
分别采用集中质量单元、板单元、杆单元与集中质量单元组合来模拟船舶与海洋工程结构上的设备,对几种常用的模型分别进行计算,并对结果进行了比较分析。
It is essential for the designer of the ship and ocean engineering structure to develop a relatively simple, accurate and practical calculation model for improving the precision of vibration prediction. In this paper, the lumped mass element, plate element and staff elements are assembled to simulate the equipment of ship and ocean engineering structures. Based on computation and comparison of several normal models, a new practical model is presented. The numerical result shows that the new model is precise and feasible. It is valuable for ocean engineering structure.
