基于NAPA的圆舭艇快速型线建模方法研究

Study on quick line-modeling method of rounded bilge boat based on NAPA

基于船舶设计NAPA软件平台,使用NAPA自带的NAPA BASIC语言,以圆舭艇为研究对象,利用"数学船型"表示艇的型线模型,通过参数输入接口输入艇的设计参数和控制参数,从而快速生成艇的型线模型,同时还能输出艇的静水力性能.并且在参数输入接口中改变参数可以得到所需要的船舶模型,从而有效地将船体型线模型设计与船舶设计软件紧密结合起来,提高了工作效率,为圆舭艇快速型线建模提供了一条新途径,并且为圆舭艇的水动力性能研究提供了方便.

Basing on NAPA-software of ship design and NAPA BASIC language, line-model and hydrostatics capabilities of rounded bilge boat were obtained. In the process, mathematic model was used to express boat＇s line- model. Design and control parameters in the parameter input interface were input. Furthermore, the needed line- model could be gotten by changing parameters in the parameter input interface. Sequentially, a new way was seeked for quick line-modeling. It may effectively link line-model design with software of ship design, improve work efficiency, and conveniently study on hydrodynamic capabilities of rounded bilge boat.
