东北大学硕士学位论文摘要I论我国振动利用工程的发展现状和发展前景摘要“振动利用工程”是研究振动与波利用的理论、技术及设备的一门新兴的学科。它是机械振动学三个主要分支（机械振动的理论基础、机械振动的控制和机械振动的利用）中与人类生活和生产联系十分密切的一个分支，“振动利用工程”是融机械学、力学、电工学与电子学、控制理论等为一体的交叉学科，是一门面向工程实际的技术科学。在人类生活与生产等各个方面均获得广泛应用，并已扩展到生物工程与社会经济等众多领域，目前它正处在迅速发展过程中，由于该学科所涉及的有关技术与工农业生产及人类生活联系十分密切，已正真成为人类生产活动与生活过程中一种不可缺少的手段与必要的机制。振动（包括波动）按其类型可分为：线性与近似于线性的振动、非线性振动、波动以及电磁振荡等，因此，相应地可把振动的利用划分为在这些方面的应用。振动与波不仅已广泛应用工程技术部门，目前正在向信息技术、生物工程、社会经济领域以及人类日常生活的各个方面，预计它还会得到更进一步的发展。本文将对以上一些方面的发展做较系统的介绍，其中包括了我科研组在研究和发展“振动利用工程”中所做的一些贡献。关键词：振动利用；线性振动；非线性振动；波动；电磁振荡东北大学硕士学位论文AbstractIIRecentDevelopmentofVibrationUtilizationEngineeringSubjectAbstract“Vibrationutilizationengineering”isanewsubject,whichmainlystudyonthetheory,technologyandequipmentofvibrationandwave.Itisalsotheoneoftreemainbranches(theoreticalbasis,controlandutilizationofmechanicalvibration),whichiscloselyrelatedtohumanlifeandproduction.VibrationutilizationengineeringisaninterdisciplinarysubjectandatechnologysciencefacingpracticalEngineering,whichmergesmechanics,electrotechnics,electronicsandcontroltheory.Ithasfoundwideapplicationinhumanlifeandproductionandhasbeenextendedtovariedfields,suchasbioengineering,socialeconomy,etc.Atpresent,itisintheprocessofrapiddevelopmentandbecomesanindispensablemeansandessentialmechanismasaresultofthecloserelationofrelatedtechnologyofthissubjectandhumanlifeandproduction.Vibration(includingwave)canbedividedinto,accordingtoitstype,linearandnearlinearvibration,nonlinearvibration,wave,electromagneticoscillation,etc.Accordingly,vibrationutilizationisalsodividedbythis.Vibrationandwaveisnotonlyappliedinengineeringtechnologydepartmentsbutalsoininformationtechnology,bioengineering,socialeconomyandeveryaspectofthehumandailylife.Itisexpectedthatvibrationandwavewillfurtherdevelop.Inthispaper,thedevelopmentofsomeaspectsinvibrationutilizationsubjectwillbesystematicallyintroduced,includingsomecontributionsofourteamcollegesinprocessofstudyinganddevelopingvibrationutilizationengineering.Keywords:Vibrationutilizationengineering;linearvibration;non-linearvibration;wave;electromagneticoscillatio东北大学硕士学位论文目录III目录摘要...........................................................................................................................................................................IAbstract......................................................................................................................................................................II目录.........................................................................................................................................................................III第1章振动利用工程的概念和理论框架.........................................................................................................-1-1.1提出了“振动利用工程”的概念..................................................................................................................-1-1.2构建了该学科的理论框架.........................................................................................................................-1-1.3完善了该学科某些分支的理论.................................................................................................................-1-第2章研究了若干新的工艺理论与技术.........................................................................................................-2-第3章研究出多种新型振动机构.....................................................................................................................-3-3.1惯性共振式概率筛的近共振机构.............................................................................................................-3-3.2软式与硬式组合的复杂分段线性非线性的近共振振动筛.....................................................................-4-3.3双激振器驱动由内圆锥组成的振动破碎机.............................................................................................-4-3.4激振器偏转式大型冷烧结矿振动筛的自同步非共振机构.....................................................................-5-3.5振动同步传动的自同步新机构.................................................................................................................-5-第4章非线性动力学理论在振动机械的应用.................................................................................................-6-4.1提出了惯性力项为非线性的力学新模型.................................................................................................-6-4.2提出了不对称的软式的分段线性的非线性的力学模型.........................................................................-7-4.3构建了带有间隙的滞回非线性的力学模型.............................................................................................-8-4.4构建了振动机分段慢变与双参数慢变的非线性的动力学模型.............................................................-9-4.5研究了大长度振动机弹性弯曲的理论.....................................................................................................-9-第5章双激振器的同步理论...........................................................................................................................-10-5.1激振器偏转式的自同步振动机的同步性判据.......................................................................................-10-5.2出倍频同步自同步振动机的同步理论及振动同步...............................................................................-10-5.3将同步理论扩
