In order to transmit power there must be a difference in the belt tension as it approaches and leaves the drive pulley. These conditions are true for steady state running, starting, and stopping. Traditionally, belt designs are based on static calculations of running forces. Since starting and stopping are not examined in detail, safety factors are applied to static loadings (Harrison, 1987). This paper will primarily address the starting or acceleration duty of the conveyor. The belt designer must control starting acceleration to prevent excessive tension in the belt fabric and forces in the belt drive system (Suttees, 1986). High acceleration forces can adversely affect the belt fabric, belt splices, drive pulleys, idler pulleys, shafts, bearings, speed reducers, and couplings. Uncontrolled 7acceleration forces can cause belt conveyor system performance problems with vertical curves, excessive belt take-up movement, loss of drive pulley friction, spillage of materials, and festooning of the belt fabric. The belt designer is confronted with two problems, The belt drive system must produce a minimum torque powerful enough to start the conveyor, and controlled such that the acceleration forces are within safe limits. Smooth starting of the conveyor can be accomplished by the use of drive torque control equipment, either mechanical or electrical, or a combination of the two (CEM, 1979).What is the best belt conveyor drive system? The answer depends on many variables. The best system is one that provides acceptable control for starting, running, and stopping at a reasonable cost and with high reliability (Lewdly and Sugarcane, 1978). Belt Drive System For the purposes of this paper we will assume that belt conveyors are almost always driven by electrical prime movers (Goodyear Tire and Rubber, 1982). The belt "drive system" shall consist of multiple components including the electrical prime mover, the electrical motor starter with control system, the motor coupling, the speed reducer, the low speed coupling, the belt drive pulley, and the pulley brake or hold back (Cur, 1986). It is important that the belt designer examine the applicability of each system component to the particular application. For the purpose of this paper, we will assume that all drive system components are located in the fresh air, non-permissible, areas of the mine, or in non-hazardous, National Electrical Code, Article 500 explosion-proof, areas of the surface of the mine.Belt Drive Component Attributes Size.Certain drive components are available and practical in different size ranges. For this discussion, we will assume that belt drive systems range from fractional horsepower to multiples of thousands of horsepower. Small drive systems are often below 50 horsepower. Medium systems range from 50 to 1000 horsepower. Large systems can be considered above 1000 horsepower. Division of sizes into these groups is entirely arbitrary. Care must be taken to resist the temptation to over motor or under motor a belt flight to enhance standardization. An over motored drive results in poor efficiency and the potential for 8high torques, while an under motored drive could result in destructive overspending on regeneration, or overheating with shortened motor life (Lords, et al., 1978).Torque Control. Belt designers try to limit the starting torque to no more than 150% of the running torque (CEMA, 1979; Goodyear, 1982). The limit on the applied starting torque is often the limit of rating of the belt carcass, belt splice, pulley lagging, or shaft deflections. On larger belts and belts with optimized sized components, torque limits of 110% through 125% are common (Elberton, 1986). In addition to a torque limit, the belt starter may be required to limit torque increments that would stretch belting and cause traveling waves. An ideal starting control system would apply a pretension torque to the belt at rest up to the point of breakaway, or movement of the entire belt, then a torque equal to the movement requirements of the belt with load plus a constant torque to accelerate the inertia of the system components from rest to final running speed. This would minimize system transient forces and belt stretch (Shultz, 1992). Different drive systems exhibit varying ability to control the application of torques to the belt at rest and at different speeds. Also, the conveyor itself exhibits two extremes of loading. An empty belt normally presents the smallest required torque for breakaway and acceleration, while a fully loaded belt presents the highest required torque. A mining drive system must be capable of scaling the applied torque from a 2/1 ratio for a horizontal simple belt arrangement, to a 10/1 ranges for an inclined or complex belt profile.Each drive system will require a control system to regulate the starting mechanism. The most common type of control used on smaller to medium sized drives with simple profiles is termed "Open Loop Acceleration Control". In open loop, the control system is previously configured to sequence the starting mechanism in a prescribed manner, usually based on time. In open loop control, drive-operating parameters such as current, torque, or speed do not influence sequence operation. This method presumes that the control designer has adequately modeled drive system performance on the conveyor. For larger or more complex 9belts, "Closed Loop" or "Feedback" control may he utilized. In closed loop control, during starting, the control system monitors via sensors drive operating parameters such as current level of the motor, speed of the belt, or force on the belt, and modifies the starting sequence to control, limit, or optimize one or wore parameters. Closed loop control systems modify the starting applied force between an empty and fully loaded conveyor. The constants in the mathematical model related to the measured variable versus the system drive response are termed the tuning constants. These constants must be properly adjusted for successful application to each conveyor. The most common schemes for closed loop control of conveyor starts are tachometer feedback for speed control and load cell force or drive force feedback for torque control. On some complex systems, It is desirable to have the closed loop control system adjust itself for various encountered conveyor conditions. This is termed "Adaptive Control". These extremes can involve vast variations in loadings, temperature of the belting, location of the loading on the profile, or multiple drive options on the conveyor. There are three common adaptive methods. The first involves decisions made before the start, or 'Restart Conditioning'. If the control system could know that the belt is empty, it would reduce initial force and lengthen the application of acceleration force to full speed. If the belt is loaded, the control system would apply pretension forces under stall for less time and supply sufficient torque to adequately accelerate the belt in a timely manner. Since the belt only became loaded during previous running by loading the drive, the average drive current can be sampled when running and retained in a first-in-first-out buffer memory that reflects the belt conveyance time. Then at shutdown the FIFO average may be use4 to precondition some open loop and closed loop set points for the next start. The second method involves decisions that are based on drive observations that occur during initial starting or “Motion Proving". This usually involves a comparison In time of the drive current or force versus the belt speed. if the drive current or force required early in the sequence is low and motion is initiated, the belt must be unloaded. If the drive current or force required is high and motion is slow in starting, the conveyor 10must be loaded. This decision can be divided in zones and used to modify the middle and finish of the start sequence control. The third method involves a comparison of the belt speed versus time for this start against historical limits of belt acceleration, or 'Acceleration Envelope Monitoring'. At start, the belt speed is measured versus time. This is compared with two limiting belt speed curves that are retained in control system memory. The first curve profiles the empty belt when accelerated, and the second one the fully loaded belt. Thus, if the current speed versus time is lower than the loaded profile, it may indicate that the belt is overloaded, impeded, or drive malfunction. If the current speed versus time is higher than the empty profile, it may indicate a broken belt, coupling, or drive malfunction. In either case, the current start is aborted and an alarm issued.The best belt starting system is one that provides acceptable performance under all belt load Conditions at a reasonable cost with high reliability. No one starting system meets all needs. The belt designer must define the starting system attributes that are required for each belt. In general, the AC induction motor with full voltage starting is confined to small belts with simple profiles. The AC induction motor with reduced voltage SCR starting is the base case mining starter for underground belts from small to medium sizes. With recent improvements, the AC motor with fixed fill fluid couplings is the base case for medium to large conveyors with simple profiles. The Wound Rotor Induction Motor drive is the traditional choice for medium to large belts with repeated starting duty or complex profiles that require precise torque control. The DC motor drive, Variable Fill Hydrokinetic drive, and the Variable Mechanical Transmission drive compete for application on belts with extreme profiles or variable speed at running requirements. The choice is dependent on location environment, competitive price, operating energy losses, speed response, and user familiarity. AC Variable Frequency drive and Brush less DC applications are limited to small to medium sized belts that require precise speed control due to higher present costs and complexity. However, with continuing competitive and technical improvements, the use of synthesized waveform electronic drives will expand.南京理工大學(xué)泰州科技學(xué)院學(xué)生畢業(yè)設(shè)計（論文）中期檢查表學(xué)生姓名 王鋒 學(xué) 號 0501510137 指導(dǎo)教師 張衛(wèi) 張少文課題名稱 防恐電子擋車器設(shè)計——擋車器總體及控制系統(tǒng)設(shè)計難易程度 偏難 適中 √ 偏易選題情況工作量 較大 合理 √ 較小任務(wù)書 有 √ 無開題報告 有 √ 無符合規(guī)范化 的要求外文翻譯質(zhì)量 優(yōu) 良 √ 中 差學(xué)習(xí)態(tài)度、出勤情況 好 一般 √ 差工作進度 快 按計劃進行 √ 慢中期工作匯報及解答問題情況優(yōu) 良 中 √ 差中期成績評定：中所在專業(yè)意見：學(xué)習(xí)態(tài)度認(rèn)真，基本按進度和規(guī)定要求完成設(shè)計任務(wù)。負(fù)責(zé)人： 2009 年 4 月 1 日 南 京 理 工 大 學(xué)畢業(yè)設(shè)計（論文）任務(wù)書系 部 ： 機械工程系專 業(yè) ： 機械工程及自動化學(xué) 生 姓 名： 王鋒學(xué) 號：0501510137設(shè)計 (論文 )題目 ： 防恐電子擋車器設(shè)計擋車器總體及控制系統(tǒng)設(shè)計起 迄 日 期 : 2009 年 3 月 9 日～ 2009 年 6 月 14 日設(shè)計 (論文 )地點 : 南京理工大學(xué)泰州科技學(xué)院指 導(dǎo) 教 師 : 張衛(wèi) 張少文專 業(yè) 負(fù) 責(zé) 人 : 龔光容發(fā)任務(wù)書日期: 2009 年 2 月 26 日任務(wù)書填寫要求1．畢業(yè)設(shè)計（論文）任務(wù)書由指導(dǎo)教師根據(jù)各課題的具體情況填寫，經(jīng)學(xué)生所在專業(yè)的負(fù)責(zé)人審查、學(xué)院（系）領(lǐng)導(dǎo)簽字后生效。此任務(wù)書應(yīng)在畢業(yè)設(shè)計（論文）開始前一周內(nèi)填好并發(fā)給學(xué)生；2．任務(wù)書內(nèi)容必須用黑墨水筆工整書寫或按教務(wù)處統(tǒng)一設(shè)計的電子文檔標(biāo)準(zhǔn)格式（可從教務(wù)處網(wǎng)頁上下載）打印，不得隨便涂改或潦草書寫，禁止打印在其它紙上后剪貼；3．任務(wù)書內(nèi)填寫的內(nèi)容，必須和學(xué)生畢業(yè)設(shè)計（論文）完成的情況相一致，若有變更，應(yīng)當(dāng)經(jīng)過所在專業(yè)及學(xué)院（系）主管領(lǐng)導(dǎo)審批后方可重新填寫；4．任務(wù)書內(nèi)有關(guān)“學(xué)院（系） ”、 “專業(yè)”等名稱的填寫，應(yīng)寫中文全稱，不能寫數(shù)字代碼。學(xué)生的“學(xué)號”要寫全號（2000 級為 10位數(shù)） ，不能只寫最后 2 位或 1 位數(shù)字；5．任務(wù)書內(nèi)“主要參考文獻”的填寫，應(yīng)按照國標(biāo) GB 7714—87《文后參考文獻著錄規(guī)則》的要求書寫，不能有隨意性；6．有關(guān)年月日等日期的填寫，應(yīng)當(dāng)按照國標(biāo) GB/T 7408—94《數(shù)據(jù)元和交換格式、信息交換、日期和時間表示法》規(guī)定的要求，一律用阿拉伯?dāng)?shù)字書寫。如“2004 年 3 月 15 日”或“2004-03-15” 。畢 業(yè) 設(shè) 計（論 文）任 務(wù) 書1．本畢業(yè)設(shè)計（論文）課題應(yīng)達到的目的：本課題擬設(shè)計一種剛性擋車器，在重點進行抗沖撞設(shè)計的同時，充分發(fā)揮計算機控制技術(shù)的優(yōu)勢，實現(xiàn)系統(tǒng)的自動控制。要求學(xué)生在對剛性擋車器的工作條件和功能需求作出認(rèn)真分析的基礎(chǔ)上，做好擋車器總體方案設(shè)計及控制系統(tǒng)的詳細(xì)設(shè)計。通過這一典型機電一體化產(chǎn)品的開發(fā)設(shè)計，培養(yǎng)學(xué)生綜合運用所學(xué)專業(yè)知識設(shè)計開發(fā)新產(chǎn)品及解決工程實際問題的能力。2．本畢業(yè)設(shè)計（論文）課題任務(wù)的內(nèi)容和要求（包括原始數(shù)據(jù)、技術(shù)要求、工作要求等）：本課題要求學(xué)生在對剛性擋車器的工作條件和功能需求作出認(rèn)真分析的基礎(chǔ)上，做好擋車器總體方案設(shè)計及控制系統(tǒng)的詳細(xì)設(shè)計。具體內(nèi)容及要求如下：（1）調(diào)查研究、查閱及翻譯文獻資料，撰寫開題報告；（2）擋車器工作條件及功能需求分析；（3）總體方案設(shè)計與計算；（4）控制系統(tǒng)的詳細(xì)設(shè)計；（5）文檔整理、撰寫畢業(yè)設(shè)計說明書及使用說明書。相關(guān)設(shè)計技術(shù)條件及要求如下：（1）路幅寬：5 米；（2）極限沖擊力：1000KN；（3）動作時間：10s；（4）控制核心：單片機；（5）控制方式：現(xiàn)場按鈕控制、中央計算機集中控制、地感應(yīng)智能控制。畢 業(yè) 設(shè) 計（論 文）任 務(wù) 書3．對本畢業(yè)設(shè)計（論文）課題成果的要求〔包括畢業(yè)設(shè)計論文、圖表、實物樣品等〕：（1）資料翻譯譯文及開題報告；（2）總體方案設(shè)計與計算；（3）單片機控制系統(tǒng)原理圖、電子線路板圖及控制系統(tǒng)的軟件；（4）畢業(yè)設(shè)計說明書及使用說明書。4．主要參考文獻：[1] 張俊謨.單片機中級教程—原理與應(yīng)用[M].第 2 版,北京:北京航空航天大學(xué)出版社,2006.[2] 孫桓,陳作模,葛文杰.機械原理[M].第七版,北京:高等教育出版社,2006.[3] 濮良貴,紀(jì)名剛.機械設(shè)計[M].第八版,北京:高等教育出版社,2006.[4] 尹志強.機電一體化系統(tǒng)設(shè)計課程設(shè)計指導(dǎo)書[M].北京:機械工業(yè)出版社,2007.[5] 左建民.液壓與氣壓傳動[M].北京:機械工業(yè)出版社,2007.[6] 梁景凱,蓋玉先.機電一體化技術(shù)與系統(tǒng)[M].北京:機械工業(yè)出版社,2007.[7] 張立勛,黃筱調(diào),王亮.機電一體化系統(tǒng)設(shè)計[M].北京:機械工業(yè)出版社,2006.[8] 江思敏,姚鵬翼,胡榮,等.Protel 電路設(shè)計教程[M].北京:清華大學(xué)出版社，2002.[9] 劉朝儒,吳志軍,高政一,等.機械制圖[M].第五版,北京:高等教育出版社，2006.[10] 成大先.機械設(shè)計手冊(第 5 卷)[M]. 第三版.北京：化學(xué)工業(yè)出版社,2000. 畢 業(yè) 設(shè) 計（論 文）任 務(wù) 書5．本畢業(yè)設(shè)計（論文）課題工作進度計劃：起 迄 日 期 工 作 內(nèi) 容2009 年3 月 9 日 ～ 3 月 15 日3 月 16 日 ～ 3 月 22 日3 月 23 日 ～ 4 月 12 日4 月 13 日 ～ 5 月 10 日5 月 11 日 ～ 5 月 31 日6 月 1 日 ～ 6 月 7 日6 月 8 日 ～ 6 月 14 日接受畢業(yè)設(shè)計任務(wù)，熟悉畢業(yè)設(shè)計要求；查閱資料，完成外文資料翻譯工作。撰寫開題報告及文獻綜述。功能需求分析，總體方案設(shè)計與計算。控制系統(tǒng)硬件設(shè)計?？刂葡到y(tǒng)的軟件設(shè)計。文檔整理、撰寫畢業(yè)設(shè)計說明書。準(zhǔn)備論文答辯。所在專業(yè)審查意見：負(fù)責(zé)人： 年 月 日學(xué)院（系）意見：院（系）領(lǐng)導(dǎo)： 年 月 日
