| 摘 要： | 针对 一种超低频电动水平振动台实际的机电一体化结构，分析了其工作原理，给出了其数学模型，文中特别讨论了振动台的非线性因素，包括磁场的非线性，功率放大器输出的非线性以及动圈反应等方面。这些因素导致了谐波分量的引入，致使波形严重失真，就此提出了减少超低频电动水平振动台的非线性因素的方法。

| Abstract: | Based on the mechatronics practical structure of the ultra-low frequency electromagnetic vibration platform. this paper studies the mathematical model and the operating principle. Furthermore, some nonlinear factors of the vibration platform, such as magnetic field's nonlinear, moving-coil response and nonlinear output of power amplifiers and so on. are discussed in detail. These factors lead to a lot of harmonic vibration and severe vibration waveform distortion. So some measures to decrease the nonlinear factors are proposed for the low frequency electromagnetic vibration platform. |
