调距桨推力和转矩回归算法研究摘 要螺旋桨推力和扭矩计算是否准确至关重要，因为推力和扭矩能够计算推力方程，推力方程能够得到轮船的船速和柴油机的转速，推力方程精准研究对轮船的航行分析提供很大便利，也可以用作船员仿真考试系统，培养学员。本文对调距桨推力和转矩国内外的算法和成果进行了总结和分析，通过对比国内外调距桨推力和扭矩计算方法，得到了各自的优点与缺点。传统的调距桨推力和扭矩计算方法不够直观并且比较粗糙，不能根据不同的螺距比而得到不同的数值变化。因此我们提出了调距桨推力和扭矩的回归算法。我们所采用的回归算法不仅计算量小、简单方便，最关键的是适用于全工况范围的需求，对调距桨推力和扭矩的计算拥有一定的参考价值。本文还利用MicrosoftVisualC++6.0 进行了编程，利用插值算法计算出任意螺距比时的螺旋桨推力和转矩，进而通过公式能够得到T p、 M p的数值，又在程序中拟合了柴油机模型，最终能够得到船速和转速并进行了数据验证。回归算法的出现能够弥补传统算法的不足，更利于通过船员仿真考试系统使学员详细了解调距桨的特性关键词：螺旋桨推力和扭矩；回归算法；MicrosoftVisual C++ 6.0；内插法；AbstractIt is important that the propeller thrust and torque calculations are accurate, since the thrust and torque can calculate the thrust equation. The thrust equation can be used to obtain the speed of the ship and the speed of the diesel engine. The thrust equation is an excellent tool for the ship's navigation analysis. Crew training simulation system, training students.In this paper, the algorithms and results of pitch and torque are summarized and analyzed. By comparing the thrust and torque calculation methods at home and abroad, the advantages and disadvantages are obtained. The traditional method of calculating the thrust and torque of the pitch is not intuitive and rough, and can not get different numerical changes according to the different pitch ratio. Therefore, we propose a regression algorithm for pitch and torque.We use the regression algorithm is not onl...
