作动器是主动控制的重要动力部件，用于船舶推进轴系主动控制的作动器对低频范围的输出力值有较高要求。本文以电磁作动器为研究对象，建立动力学模型，利用Ansoft Maxwell对该电磁作动器进行磁路优化分析，确定该电磁作动器具有最优磁路尺寸。通过电磁作动器仿真计算得到的电磁力大小与实际测试出的电磁力大小基本相等，证实该电磁作动器建模仿真方法的正确性。得到电磁作动器的最佳频率输出范围，说明电磁作动器具有低频大力值输出的特点。该作动器的优化方法及性能分析为船舶推进轴系等结构的低频大力值主动控制提供了理论及技术支撑。
The actuator is an important power component of active control, and the actuator used for active control of marine propulsion shafting has higher requirements for the output force in the low frequency range. In this paper, taking the electromagnetic actuator as the research object, the dynamic model is established, the magnetic circuit optimization analysis of the electromagnetic actuator is carried out by using Ansoft Maxwell, and the optimal magnetic circuit size of the electromagnetic actuator is determined. The electromagnetic force calculated by the electromagnetic actuator simulation is basically equal to the actual measured electromagnetic force, which confirms the correctness of the electromagnetic actuator modeling and simulation method，and obtains the optimal frequency output range of the electromagnetic actuator. It shows that the electromagnetic actuator has the characteristics of low frequency and large force output. The optimization method and performance analysis of the actuator provide theoretical and technical support for the low frequency large force active control of ship propulsion shafting and other structures.
