摘要

摘要 本研究的意义在于,它提出了一个考虑到水质量的船舶推进系统动力学数学模型。研究了这一现象对螺旋桨轴共振频率的影响,并获得了可控螺距螺旋桨在各种工作模式下的传递函数。本研究的目的是通过研究可视化模型的特点来改进可控螺距螺旋桨动态工作模式的计算。研究中使用了 VisSim 软件包。开发的可视化模型考虑了转速对附着在水团可变螺距螺杆上的转动惯量值的影响,并提出了一个特殊的传递函数。研究表明,这种类型的传递函数具有负反馈回路。根据频率特性应用所获得的传递函数,对螺旋桨轴在共振频率下的运行进行了分析。我们发现,在低频区域,使用所提出的传递函数来考虑增加的转动惯量,与使用现有计算方法得出的结果相比会有显著差异。

Transfer Function for a Controllable Pitch Propeller with Added Water Mass
Abstract The relevance of this study lies in the fact that it presents a mathematical model of the dynamics of the propulsion system of a ship that takes into consideration the mass of water added to it. The influence of this phenomenon on the resonant frequencies of the propeller shaft is examined, and a transfer function for a controllable-pitch propeller is obtained for various operating modes. The purpose of the study is to improve the calculation of the dynamic operating modes of a controllable-pitch propeller by examining the features of a visual models. The VisSim software package is used in the study. A visual model is developed that considers the influence of the rotational speed on the value of the rotational inertia attached to the variable-pitch screw of the mass of water, and a special transfer function is proposed. The study shows that a transfer function of this type has a loop enabling negative feedback. An analysis of the operation of the propeller shaft at its resonant frequency is conducted based on the application of frequency characteristics using the transfer functions obtained. We show that in the low-frequency region, a consideration of the added rotational inertia using the proposed transfer function leads to a significant difference compared to the result obtained with the existing calculation method.
