基于设计特征的FRIENDSHIP船型参数化方法及实现

船型设计是船舶总体设计中一项极其复杂且又重要的内容,船舶的结构设计、性能计算、总布置等都要以船型为依据,因此,如何实现船型参数化设计尤为重要。FRIENDSHIP系统为船型设计提供了基于Feature特征和仿真驱动设计的参数化方法和实现机制。在对船型参数化基本理论———特征参数、特征曲线和曲面生成等进行详细阐述的基础上,以某型船艉部裸船体为例,具体阐述了船型参数化的实现流程,以及以Feature、Curveengine和Meta surface为特征机制的船型参数化的具体步骤。以Feature特征为核心的船型参数化方法不仅能为船型曲面的快速建立提供技术支撑,还可以为性能分析和优化提供基础条件。

The Parametric Method of FRIENDSHIP Hull Form Based on Design Feature

The hull form design is a very complicated and critical content in ship’s overall design.The hull form is the basis of structure design,hydrodynamic performance and general arrangement,thus the realization of parametric design is important.FRIENDSHIP system provides parametric method and application mechanism based on feature of the ship hull and parametric driving design.Based on the hull form parameterized theories-characteristic parameters,characteristic curves and surface modeling,we introduced a hull form parametric method by Feature,Curve engine and Meta surface with the application in a real ship model.Hull parametric method provides technical support for hull surface quick modeling,and establishes advantaged elements for performance analysis and optimization.
