【摘要】 随着直线运动领域的增多，直线电机的需求不断增加。动圈式永磁直线振动电机越来越多的广泛应用在飞机、航天器、汽车、计算机硬盘、医疗器械、空气压缩机等部件内。作为直线运动的伺服执行机构或动力源，国内外都大力开发研制直线振动电机。除了样机本身的特点外，本文对动圈式直线振动样机进行了具体研究： (1)使用电磁场分析软件Ansys对几种不同类型的直线振动电机的空载磁场和静特性进行分析比较； (2)介绍了振动电机的结构和有关设计的问题，利用美国Ansoft公司的电磁分析Maxwell 2D对动圈式直线永磁振动样机的静特性进行分析，分析了磁场分布和静推力特性。 (3)动态仿真：用Ansoft软件和Mathcad数学分析软件对动圈式电机进行动态分析，搭建实验台和实验电路，具体分析了电压恒定时，频率变化对电机动态特性的影响，得出了频率单行程曲线。更多还原

【Abstract】 Moving Coil Linear Permanent Magnet Oscillatory Actuator (alias ’MCLPMOA’ ) is widely applied in aeroplane , spaceflight apparatuses,automobile,computer HD,medical treatment machines ,air compressor more and more. As the servo system or driving source of the linear motion. Besides the characteristic of the motor style, The subject of this thesis is to study on MCLPMOA and the major works in this thesis are summarized as follows:1) Several basic types of Linear Oscillatory Actuator(LOA) as well as their basic configuration and performance principle are introduced.Analysis of the static characteristic of each type of LOA: moving coil LOA, moving core LOA, moving magnet LOA by Finite Element Method, besides applied situations of each style.2) Introduction of motor structure and some question on design. Determination of the static thrust characteristics of MCLPMOA by software MAXWELL 2D of Ansoft.3 ) Realization of dynamic simulation of MCLPMOA by Ansoft software Transient, Mathcad and experiments. Introduction detailed of the frequence changes effect on dynamic characteristic , obtained of stroke vs.frequence curve.更多还原
