基于CATIA的三维船舶静水力计算研究

传统的基于二维插值的近似计算船舶静水力性能的方法在精度上有不可避免的劣势,且操作也较为繁琐。提出了一种基于船舶三维实体模型计算静水力性能的方法,该方法脱离了二维插值,以三维实体模型为基础进行计算。在CATIA平台环境下,通过制作船舶三维实体模型,再应用VB对CATIA进行功能上的二次开发来编制船舶静水力计算程序,从而实现自动提取实体模型信息,并应用这些信息进行静水力计算。最后,通过一个算例证明了该方法的易于操作性和计算可靠性。

Calculation of Ship Hydrostatic Based on CATIA

Using the traditional 2D interpolation-based method to compute hydrostatic performance of ship will result in an unfavorable accuracy and troublesome operation.A new method based on the 3D solid model was proposed,which was constructed in the CATIA environment,and combined to apply VB.NET to develop computing procedures of ship hydrostatic for secondary development.The information required for hydrostatic computation was then automatically extracted from the solid model.The good operability and reliability ...
