【摘要】：EMS磁懸浮列車作為一種新型的非接觸式地面有軌交通工具,其與傳統(tǒng)的輪軌鐵路相比,在爬坡能力、安全性、環(huán)保、經(jīng)濟性、舒適性等方面具有顯著的優(yōu)勢,在軌道交通領域具有廣闊的應用前景。采用德國TR技術的上海高速磁浮線已于2006年正式投入運營,日本采用HSST技術的東部丘陵線也于2005年投入運營,并已經(jīng)取得優(yōu)良的運營業(yè)績。我國經(jīng)過近10多年的研究,中低速磁浮列車采用了 EMS技術方案,具有自主知識產權的磁浮鐵路現(xiàn)已進入最后的工程實踐階段�？梢灶A見,未來EMS磁浮鐵路技術在我國具有廣闊的應用空間。由于EMS磁浮列車懸浮時依靠控制系統(tǒng)產生電磁力,該懸浮在受到多種車-軌因素影響時可能會發(fā)生磁浮車輛振動和軌道振動相互影響的特有現(xiàn)象。雖然經(jīng)過國內外多年的研究,但在工程實踐中并沒有能夠完全解決。在我國磁浮列車試驗線中,也出現(xiàn)了很多與車-軌系統(tǒng)振動相關的問題,迫切需要解決。因此,為磁浮鐵路國產化展開相應的理論研究顯得十分急迫。針對上述問題,本文將從EMS磁浮列車系統(tǒng)振動的內在機理出發(fā),跟蹤國內外磁浮車輛動力學和控制理論等相關領域的最新動態(tài),針對EMS磁浮系統(tǒng)振動機理進行較為詳細的研究,并尋找有效抑制磁浮系統(tǒng)振動方法。EMS磁浮列車不同于傳統(tǒng)輪軌鐵路的關鍵在于使用電磁力代替了輪軌系統(tǒng)中的一系懸掛支撐力,這是磁浮系統(tǒng)特有振動問題的根源。本文第二章基于國內外的研究成果,建立了單磁鐵懸浮系統(tǒng),考慮車輛-軌道之間的相互耦合作用,對磁浮系統(tǒng)起浮后的靜態(tài)懸浮過程進行了分析,理論分析了系統(tǒng)振動的內在機理,討論了懸浮控制器及車-軌主要參數(shù)對系統(tǒng)振動的內在影響,并采用數(shù)值仿真的方法驗證了理論分析的結論。為展開磁浮系統(tǒng)振動的研究提供了理論基礎。EMS磁浮列車在高速運行時,影響磁浮系統(tǒng)振動的因素較列車靜浮時更加復雜。隨著磁浮列車速度的提高,車輛以更快的速度通過軌道,必然使軌道的形變和振動增大,車-軌耦合后使整個車廂-懸浮架-軌道的系統(tǒng)振動變得更加劇烈,對磁浮車的穩(wěn)定運行造成極大的影響。本文第三章研究了 EMS磁浮列車運行中的振動特性,理論分析了懸浮控制器、車-軌主要參數(shù)對于振動影響的機理。提出了一種快速判斷彈性軌道上磁浮列車動力穩(wěn)定性的新方法,給出了相關的判據(jù),并通過數(shù)值仿真驗證了理論分析的結論。該研究為EMS磁浮鐵路系統(tǒng)的設計提供了理論依據(jù)。中低速EMS磁浮列車具有爬坡能力強的特點,但磁浮列車通過較大坡度的軌道時由于軌道快速變化,使系統(tǒng)穩(wěn)定性變差,對車輛的安全性和舒適性造成影響。針對磁浮系統(tǒng)軌道在坡道處的線路設計國內外并無相應的理論研究成果的情況,本文第四章建立了磁浮車輛通過軌道變坡點的系統(tǒng)模型,理論分析了折線變坡點及豎曲線兩種軌道條件下,車輛速度及軌道曲線等主要參數(shù)對系統(tǒng)振動的影響,最后進行相應的仿真驗證了理論推導的結論。該研究對于中低速EMS磁浮系統(tǒng)在上下坡處的軌道設計提供了相應的理論依據(jù),對于高速EMS磁浮系統(tǒng)的軌道設計也具有參考價值。形成EMS磁浮列車振動的因素很多,如行駛中切割空氣形成的力、推進及各種輔助設備形成的振動、車-軌耦合、軌道不平順等。由于這些因素的存在,其振動本身不可避免,如何抑制振動,提高磁浮列車行駛的平穩(wěn)性、舒適性是一個系統(tǒng)工程。但由于EMS磁浮列車在國內的工程化應用處于起步階段,其相關的減振技術在理論研究、工程實踐方面還太少。本文在第五章中介紹了磁浮系統(tǒng)軌道譜及車輛振動評價指標,理論分析了 EMS磁浮車輛抑制振動的基本原理,分別就磁浮列車在靜浮和運行中提出的振動抑制的方案,并進行了相應的數(shù)值仿真驗證。該研究對于國產磁浮系統(tǒng)的成功運營具有重要的工程應用價值。綜上所述,本文較系統(tǒng)的展開了 EMS磁浮系統(tǒng)振動的內在理論研究,分析了懸浮控制、車輛-軌道的主要結構、參數(shù)在系統(tǒng)振動過程中相互作用的內在機理,并分別給出了抑制車輛靜浮振動和運行中振動的具體方案,其成果填補了我國在中低速磁浮列車研究中的一些空白,為完善我國磁浮交通系統(tǒng)的國產化提供相應的理論基礎。
[Abstract]:As a non-contact surface model of the EMS maglev train rail transportation, compared with the traditional railway, the climbing ability, safety, environmental protection, economy, comfort has significant advantages, has broad application prospects in the field of rail transportation. The German TR Shanghai high-speed maglev technology the line was officially put into operation in 2006, Japan adopted HSST technology Linimo in 2005 put into operation, and achieved good operating performance in China. After nearly 10 years of studies, the low-speed maglev train uses EMS technology solutions, with independent intellectual property rights of the maglev railway has entered the final stage of engineering practice can be expected, the future of EMS maglev railway technology has a broad application space in our country. As the train suspension on control system of electromagnetic force in the EMS maglev, suspension by various vehicle The special phenomenon may occur the mutual influence of maglev vehicle vibration and rail track vibration factors. Although after years of research at home and abroad, but in engineering practice and not be able to completely solve the maglev train in China. In the test line, there are also many and train track system vibration related problems, the urgent need to solve. Therefore, for the localization of the maglev railway expansion theory to study the corresponding is very urgent. Aiming at the above problems, this paper from the perspective of internal mechanism of vibration of EMS maglev train system, tracking the latest developments at home and abroad the maglev vehicle dynamics and control theory and other related fields, and make a relatively detailed study on vibration mechanism of EMS maglev system, and to find the effective vibration suppression method of maglev system of.EMS maglev train key is different from the traditional railway is the use of electromagnetic force instead of a series of supporting wheel system in suspension Support force, which is the root of a particular vibration problem of maglev system. In the second chapter, based on the research results at home and abroad, the establishment of a single magnet suspension system, considering the coupling interaction between vehicle and track, the maglev system static floating suspension process is analyzed after the theoretical analysis, the intrinsic mechanism of the vibration of the system, the the influence of the main parameters of suspension controller and vehicle track on the vibration of the system is discussed, and the method of numerical simulation to verify the theoretical results. Provide a theoretical basis for.EMS maglev train is running at high speed for research on maglev system vibration, impact factor of maglev system vibration is more complicated. The static floating train with maglev the increase of the train speed, the vehicle at a faster speed by rail, will inevitably lead to deformation and vibration increases, vehicle track coupling vibration system so that the whole car suspension frame rail It has become more intense, and caused a great impact on the running stability of maglev vehicle. The third chapter studies the vibration characteristics of the EMS maglev train operation, the theoretical analysis of the suspension controller, vehicle track main parameters on the vibration mechanism of influence. This paper proposes a new method of rapid judgment on elastic track of maglev train dynamic stability, are given the relevant criterion, and the conclusion of theoretical analysis is verified by numerical simulation. The research provides a theoretical basis for the design of EMS maglev railway system. The low-speed maglev train EMS has the characteristics of strong climbing ability, but the larger slope of the maglev train track by track of rapid change, make the system instability caused by impact the safety and comfort of the vehicle. For the maglev system in rail ramp circuit design at home and abroad there is no corresponding theoretical research results, the fourth chapter of this article The system model is established by the maglev vehicle on track, the theoretical analysis of two kinds of track line slope changing points and vertical curves under the influence of the main parameters of vehicle speed and track curve of the vibration of the system, finally verify the theoretical conclusion of the corresponding simulation. The research for low speed maglev system EMS downhill at the track on provide the corresponding theoretical basis for design, also has a reference value for EMS high speed maglev system design. Many factors in the formation of rail vibration of EMS maglev train, such as air travel in the form of cutting force, vibration and various auxiliary equipment in the formation of the vehicle track coupling, track irregularity and so on. Because of the existence of these factors, the vibration itself is inevitable, how to restrain the vibration, improve the stability of the maglev train running, comfort is a system engineering. But because of the EMS maglev train in China. The process used in the initial stage, the related vibration technology in the theoretical research, engineering practice is too little. This paper introduces the evaluation index system of maglev vehicle vibration and track spectrum in the fifth chapter, the theoretical analysis of the basic principle of EMS maglev vehicle vibration, vibration respectively on the maglev train in static and running forward the suppression scheme, and numerical simulations were conducted accordingly. The study has important engineering application value for the successful operation of domestic maglev system. To sum up, this paper systematically researched the theory of intrinsic vibration of EMS maglev system, analyzes the main structure of the suspension control, vehicle track, the internal mechanism of the interaction parameters the vibration in the system in the process, and the concrete scheme to suppress the vibration of the vehicle vibration and static floating operation are given, the results fill in our country in medium and low speed maglev trains Some gaps in the study provide a theoretical basis for improving the localization of the maglev transportation system in China.
