船舶推进系统是一个复杂的非线性系统，如何实现推进系统与船体特性的合理匹配是当前船舶动力领域研究的热点问题。因此，开展船机桨匹配特性研究对提高船舶整体性能具有非常重要的指导意义。本文基于Matlab/simulink仿真平台，采用模块化建模方法建立了某型船舶船机桨匹配数值模型。通过典型工况下推进系统稳态特性仿真，验证了模型准确性。在此基础上，开展了不同控制策略下加减速工况动态推进特性仿真。研究结果表明，主机功率调整越快，工况切换越迅速，是影响船舶动力系统动态特性的主要因素；螺距比变化率则会显著影响工况切换过程的稳定性，螺距比控制策略应与主机功率控制策略相适应，才能获得较好的船机桨匹配特性。
The ship propulsion system is a complex nonlinear system. How to achieve a reasonable match between the propulsion system and the characteristics of the hull is a hot topic in the field of marine power research. Therefore, conducting research on the matching characteristics of ship-engine-propeller systems is of great significance for improving the overall performance of ships. Based on the Matlab/simulink simulation platform, this paper establishes a numerical model of the ship-engine-propeller matching system using a modular modeling method. The accuracy of the model is verified through the simulation of the steady-state characteristics of the propulsion system under typical operating conditions. On this basis, dynamic propulsion characteristics simulations under different control strategies are carried out. The results show that the faster the adjustment of the engine power, the quicker switching of operating conditions are. Speed of the adjustment of engine power is the main factors affecting the dynamic characteristics of the marine power system; the change rate of pitch ratio will significantly affect the stability of the operating condition switching process, and the pitch ratio control strategy should be adapted to the engine power control strategy to achieve better matching characteristics of the ship's engine and propeller.
