超声近场悬浮稳定性分析与实验研究
首发时间:2015-11-19
摘要:目前在超声近场悬浮研究中,缺少定量判断悬浮稳定性的依据,大多关于超声近场及回复力的研究都以经典理论为基础,忽略高阶量的影响,在一个或多个假设前提下进行。本文将帧间差分法应用于超声波近场悬浮研究,设计一套针对悬浮稳定性分析的测量装置,捕捉悬浮片运动,在MATLAB环境中编写处理程序,建立实验悬浮片运动模型和回复力模型。?????

Analysis and Experiment Investigation of Near Field Acoustically Levitation Stability
Abstract:At present research in the near field acoustic levitation, lack of quantitative judgment for the stability analysis. Most researches about acoustic near-field and restoring forces based on classical theories, ignored the impacts of higher order quantities and under some assumptions. In this paper, the interframe difference algorithm was applied in the research of near-field acoustic levitation. Designed a measuring equipment for stability analysis of levitated disk. Captured the motions of levitated disk.Programmed handlers in MATLAB environment. Established movement model and restoring forces model of levitated disk.?????
Keywords: Near field acoustic levitation Stability Interframe difference algorithm Movement model Restoring forces?????
