B型螺旋桨图谱的模块化程序设计

The Modular Design of B-propeller Diagram

螺旋桨设计是整个船舶设计中的一个重要的组成部分。在船舶线型初步设计完成后，通过有效马力的估算或船舶助力试验，得出该船的有效马力曲线，由于螺旋桨设计水动力图谱的实用与可靠性，在螺旋桨设计中被广泛的应用。可是，由于其图谱量大，查找困难，使大多数使用者带来许多不便，这不仅影响螺旋桨的设计效率，也不利于螺旋桨的优化与发展。计算机软件在船舶设计中的广泛应用使得螺旋桨设计的程序模块化显得越来越有必要。针对这一实际问题，进行一些初步探讨和研究。对模块化程序作了必要的介绍，并分别以实例对本论文中所介绍的程序进行分别验证，还将由计算机程序设计的结果与人工设计的结果进行对比和分析。螺旋桨图谱模块化程序设计将为计算机辅助船舶螺旋桨设计奠定基础，在今后的螺旋桨设计过程中必将得以推广和应用。

Propeller design of the whole ship design as an important component. Shipping Line in the preliminary design is completed, through effective horsepower estimates or help pilot the ship, the ship that the effective power curve, because the propeller design dynamic map of the water utility and reliability in the design of the propeller was widely used. However, because of its large map, find difficult to bring inconvenience to most users, this not only affects the efficiency of the design of the propeller, the propeller is not conducive to the optimization and development. Computer software in ship design is a wide range of applications. The modular design of the propeller procedures become increasingly necessary, This paper is the practical response to this problem, some preliminary exploration and study. The main contents of this paper is as following： the procedures which proved by using real example in the paper, and the contrast and analysis about the result coming from computer procedures calculation and artificial design. computer propeller diagram design will be the base of the modem computer ship propeller design, which will be wildly used and spread in the propeller design.
