【正文】 namic instability is resulted in. Thus following problems can be put forward : Mechanism of“ spectre chatter” arose from sticking sliding friction and partial hydrodynamic lubrication in rolling interface , instability condition and mechanism of constraint between smooth surface and rotating body under the circumstance of high speed ,heavy duty and boundary lubrication , Lubrication film absorption mechanism and physical chemistry behaviour of interface of unceasingly regenerative surface ,the relationship between rheological characteristic and machine operation parameters. 3. 3 Multi Body Non Linear Contact Mechanism Under the Condition of Extra High Pressure Field To build the super strength pressure field on large area is one of basic function of material processing machine , and it is also necessary to 5 form by once large size structure element (such as spacecraft , intercontinental vehicles ,car and large scale aeroplane etc) . The ability to build super strong pressure field is one of important feature and the base of independent national defense. Under the circumstance of super strength pressure field ,multi body strong nonhertz contact and non linear friction will be produced ,thus local permanent deformation and degrading of element accuracy may be led. New theory foundation of design of machine with super strength pressure field will be furnished through study of multi body strong non hertz contact mechanism , multi body non linear friction mechanism (such as providing force displacement mixed solving process of three dimension multi body) . 3. 4 Load Distribution Law in Multi Sliding Pair With Structure Bias Load With regard to statically indeterminate structure ,load distribution of constraint point is determined by deformation patibility condition. However ,concerning some plane large size statically indeterminate structure with sliding degree of freedom in third dimension ,load distribution can not be determined by deformation patibility condition. Thus new theory basis will be provided by analyzing of contact behaviour and mechanism of sliding pair (such as creep ,force of friction ,integral deformation patibility condition ,etc) . 3. 5 Coupling Mechanism and Stability of Multi Physical Fields in Material Processing Systems In the wake of system function being more and more diversified , conventional technology limits in material processing machine is being broke through unceasingly ,system structure also bees increasingly plicated ,and system performance bees increasingly multi causal . For example ,any instantaneous state of roller in fast rolling mills is affected by elastic deformation ,plastic flow ,heat transfer process , hydro dynamic lubrication process ,interface physical chemistry molecular state and so on . In addition ,electromechanical coupling in processing system have already gone beyond conventional concept ,for instance ,some singular point phenomenon (such as micro variable can be transformed into macro variable) ,are present ,thus roller operation instability may be led by perturbation[8 ] . Therefore ,this subject will study the interaction mechanism of multi physical field and the influence on processing system stability and processing material quality started with analysis of micro state of executive body. 6 3. 6 Multi Te chnology Integration and Coalescence of Accurate Control The material processing machine ,which operate under the circumstance of extraordinary physical field ,is a plicated large scale system ,and some parameters of the system vary on feasible field boundary 。例如：在高溫環(huán)境下能使那些高溫波或者脈沖以超過(guò) 104~106K/s的速度冷卻下來(lái)；將外表面的凝固、變形合成一體，然后在將超強(qiáng)接觸面應(yīng)力重新組合成新的分界面；融化的大 金屬薄片的湍流；隨機(jī)的低頻率磁場(chǎng)用于金屬末加熱的微波、用于大量凝固的超聲波等等都已經(jīng)被應(yīng)用了。 在高壓場(chǎng)條件下非線性接觸式機(jī)械裝置 在大范圍內(nèi)組建一個(gè)超強(qiáng)力壓力場(chǎng)是材料加工設(shè)備的一個(gè)基本功能。因此我們需要在重要部位采用具有新功能的原料；例如：尺度功能有傾向的材料是想當(dāng)可貴的。一般來(lái)說(shuō) ,這種設(shè)計(jì)可以使我們會(huì)學(xué)會(huì)知識(shí)體系相關(guān)鏈接 ,這暴露了不足之處。因?yàn)樵诳刂颇Ｐ椭卸喾N交互作用的存在，根據(jù)退耦控制模型而建立綜合框架是必要的；精確的控制基于綜合技術(shù)。它們影響著材料加工設(shè)備抗摩擦裝置的成型。 （ 3）原料加工處理正在向高速、重載和高精度在線控制方向上邁進(jìn)。 procession machine 。功能材料 12 1 機(jī)械材料加工的時(shí)代背景 在人類進(jìn)步的一段長(zhǎng)時(shí)間范圍內(nèi)，許多工具、機(jī)械和方法被提出來(lái)；不同的原料用不同的工具來(lái)加工。產(chǎn)品的精確度指 數(shù)可以列舉如下：宏觀上精確度可達(dá)到 ，微觀上的晶狀體結(jié)構(gòu)非常均勻，濃度誤差在 。 負(fù)荷分配規(guī)律 關(guān)于超靜定結(jié)構(gòu)，抑制點(diǎn)的負(fù)荷分配規(guī)律由相容性條件決定。因此，它在我們四年的大學(xué)生活中占有重要的地位。 轉(zhuǎn)眼間 4周的機(jī)械制造技術(shù)和專用夾具的設(shè)計(jì)就結(jié)束了 ,周圍的課程設(shè)計(jì)審查對(duì)生活的感悟作為一個(gè)提升的過(guò)程 ,并在課程設(shè)計(jì) ,會(huì)不斷地看到教材 ,看參考書(shū)看資料 ,遇到問(wèn)題卻不明白我們一起分析或向老師請(qǐng)教等找到一個(gè)有用的與我們的設(shè)計(jì)數(shù)據(jù)和資料 ,然后他們會(huì)成為我們的設(shè)計(jì)為原料 ,通過(guò)這種設(shè)計(jì)我們學(xué)到了很多的知識(shí) ,學(xué)習(xí)并熟悉與查表 ,檢查參考書(shū) ,也掌握了證明和 CAD相關(guān)的操作 ,因?yàn)椴糠止に囋O(shè)計(jì)有著深刻的認(rèn)識(shí)和理解的夾具設(shè)計(jì)也有了一定的了解 ,知道一些基本的夾具的具體結(jié)構(gòu)部件 ,如 皮瓣 ,鉆套 ,頂頭??。因此新的基礎(chǔ)理論由分析接觸行為和變形裝置獲得（例如：摩擦力、變形相容性條件，等等）。這樣的話，那些特別性能的原料就能被處理加工了。在 當(dāng)前世界中日益激烈的競(jìng)爭(zhēng)和人們追求幸福生活的今天，物質(zhì)的功能已經(jīng)遠(yuǎn)遠(yuǎn)超出了人類現(xiàn)有的并不斷增長(zhǎng)的知識(shí)及想象。and thereafter a brief discussion is given. Keywords: interface。 （ 2）突破傳統(tǒng)的物質(zhì)限制，將溶化、凝固、造型一體化，然后加熱得到具有特殊功能的原料，這樣就可以降低加工費(fèi)用。關(guān)
