摘要隨著對地鐵列車舒適性、平穩性要求的提高，有必要運用模態分析技術了解其結構動力特性，為車體結構的合理設計提供依據。It emphasizes on the analyse of using syntony demodulation technology to final the long - distance coming train. at the same time, it gives a preliminary analyse in the signal for different cases, takes a research on the identified technology for the coming train, designs and assembles the hardware and software of this system. all of them have got past the test on the spot and got a satisfying result
課題中的關鍵是如何得到列車運行信號的特徵規律，在本文中對這些列車接近信號的一些分析方法作了介紹，著重分析了採用共振解調技術發現遠程來車的信號，同時針對不同情況下的信號進行了初步分析，研究了來車的識別技術，並對系統的軟硬體進行了設計和組裝，通過了現場試驗，得到了令人滿意的結果To solve the problem of the fear of inadequacy of armor protection on the already heavily armored kv - 1 model 1941, it was decided to bring the armor protection of the turret up to a thickness to 75mm. since the capability of producing such a thick armor plate was lacking at the time, so an interim solution was to use bolt on armor, 25 mm of thickness, bolt directly to the outside of the turret and some other parts of the hull. this type was usually referred to as kv - 1s ehkranami
針對kv - 1 1941年型的裝甲防護能力不足的問題，設計人員進行了一系列強化裝甲的工作，改進后的kv - 1的炮塔裝甲達到了大約75毫米的厚度但在具體製造中由於為kv坦克提供裝甲鋼板的工廠沒有能力生產必要厚度的裝甲鋼板，因此，作為臨時解決方案用螺栓在車體和炮塔上加裝了25毫米厚的附加裝甲，這種改進的kv坦克被命名為kv - 1附加裝甲型。A uniform cooling system of the motor and its controller is designed to solve the cooling problem and the problem of the motor and its controller being deposited separately
摘要一種電機和電機驅動器的一體化散熱系統能夠很好地解決電動汽車中電機和電機驅動器的冷卻問題，同時可以解決電機和電機驅動器的分離布置帶來的一系列問題。For the modeling of this kind of problem, because the time - order curves of viaduct column bearing the loads of vehicles are expect to get, the present finite element analysis software ? ansys can be used to solve it quite well
對這一問題的計算，只需能夠求得列車武漢理工大學博士學位論文荷載作用下橋墩的時程曲線，則現有的有限元軟體ansys己能較好地求解。Discussing the structure of the data management system lor train diagram, and proposing a web - based distributed application settlement scheme which bring convenience to the users
對列車運行圖數據管理系統採用的體系結構進行了討論。並提出了基於動態web的分散式應用解決方案，使系統的使用更加靈活方便。The main research contents are as follovvs : after the analyzing of the process of making train diagram, according with its character, and take into account the trend of innovation, chooses the total solution based on the b / s architecture, 3 - tier operation distributed and 2 - tier data distributed to separate the data from operation and simplify the development and maintenance ; the e - r data model that is accord with the 3nf criterion is designed after analyzing the data structure of the train diagram system. emphasis on the permission security of the distributed system, take the view schema, coupled with the login authentication and permissions validation, to ensure the data accessing domination, and take the synchronization, error control, and restore capability to advance the data security ; on the basis of b / s solution architecture, after comparing the existing transportation technologies, b - isdn and adsl is selected as the major solution architecture based on the package - svvitched networks. furthermore, error control, firewall, and encryption techniques are introduced to prevent the hacker attack and ensure the networks safety
論文的主要研究內容包括：對目前我國列車運行圖管理體制和編制流程進行詳細分析，根據其「幾上幾下」的特點，並結合未來「網運分離」體制改革的變化預測，選擇採用與之相適應的基於b s體系架構、三層業務分佈、二層數據分佈的整體方案，實現業務與數據的分離，降低開發與應用過程的復雜度和總體成本；對列車運行圖系統的數據信息進行分析，設計符合3nf規范的數據e - r關系模型，並著重研究處于分散式系統中的列車運行圖數據信息的訪問權限和數據安全問題，提出以視圖模式結合用戶識別權限審定實現數據權限劃分，以並發處理、容錯技術、恢復技術提高系統的數據安全性；在基於b s架構的系統整體方案基礎上，對當前多種數據傳輸技術進行分析比較，採用b - isdn為主幹網、 adsl為接入端的基於公用數據網路分組交換技術的系統網路體系結構，並針對網路自身安全性和黑客攻擊與侵入問題，詳細討論綜合採用差錯控制、防火墻、數據加密解密等技術手段提高系統的網路安全性能。分享友人
