摘要
采用有限元法研究了某船机舱底部结构在冲击载荷作用下的响应，论述了模型的建立、附连水质量及边界条件的处理等问题，分析了两种工况下的冲击响应。计算结果和模型实验结果吻合较好。文中所提出的改进措施已在设计、建造过程中得到采纳。
By using FEM,the response of bottom structure for the machinery compartment is investigated under impact loading. The setting-up of mathematical model,the determination of added mass and the treatment of boundary conditions are described.The impact response is analyzed under two working conditions. The calculation results show good agreement with the model tests. The improving measures proposed in the paper are adoped in the structure design.
