摘要
利用NAPA软件强大的编程能力,应用迁移矩阵法开发了用于分析船体总振动固有频率和振型的工具箱。由此自动获取计算总振动所需的几何和工况数据,从而推出了将船体三维建模、装载工况与总振动分析结合起来协同设计新方法,并将此方法成功应用于一艘散货船的总振动分析。
A toolbox to analyze the natural frequency and mode of hull global vibration is developed based on transfer matrix method, taking advantage of the powerful programming capacity in NAPA software. The geometry and loading condition data necessary for global vibration calculation can thus be obtained automatically, achieving a new collaborative design method by combining 3D hull modeling, loading condition and global vibration analysis together. This method is successfully applied to the global vibration analysis of a bulk carrier.
