摘　　要：军舰驱动用直线同步电机的牵引力特性对其性能提升有着显著的影响。为此,基于虚位移原理,提出了一种新型超导直线同步电机的磁阻力特性的解析计算方法——分段磁密双边傅里叶分解方法。首先,对该系统的牵引结构和虚位移原理做了简单介绍;接着通过系统储能的变化,利用虚位移原理推导了该模型的磁阻力解析表达式;最后利用有限元仿真验证了该原理计算的准确性,分析结果表明利用虚位移法可合理准确的分析超导直线同步电机的磁阻力特性。本文提出的新型傅里叶解析方法对军舰驱动用直线同步电机的初始电磁结构设计提供了快速准确的研究方法。The propulsion characteristics of linear synchronous motors(LSM)used for warship drive have a significant impact on their performance improvement.Therefore,based on the principle of virtual displacement,a new analytical calculation method for the detent force performance of superconducting LSM,the segmented flux density bilateral Fourier analysis is proposed.Firstly,it briefly introduces the traction structure and virtual displacement principle of the system;then,based on the changes in system energy storage,the analytical expression of the detent force of the model is derived using the principle of virtual displacement;finally,the accuracy of the principle calculation is verified through finite element simulation,and the analysis results showed that the virtual displacement method can be used to analyze the detent force characteristics of superconducting LSM reasonably and accurately.The new Fourier analysis provides a fast and accurate research method for the initial electromagnetic structure design of LSM used for warship drive.
