Being a sort of new principle micromotor in the fronitier of science. the ultrosonic motor ( usm ) is developed at recently twenty years. utilizing the stator surface particle elliptical motion excited by piezoceeramics, the usm is drived by friction force between the stator and rotor. compared with the conventional electromagnetic motor, the ultrasonic motor has the following features : high speed, high holding torque when power is off and so on. because of it ' s characteristics, the ultrasonic motor has obtained some widespread application in robots, precise instrument, house electronical appliance, sapceecraft automobile and micromechanism
超聲波電機（ ultrasonicmotor ）是近二十年來發展起來的一種新原理電機，其原理不同於傳統的電磁型電機，它是利用壓電陶瓷的逆壓電效應使定子的表面質點產生橢圓運動，通過定子和轉子之間的摩擦力驅動轉子運動。這種新型的電機與傳統電磁電機相比，具有響應快、不受電磁干擾、結構緊湊、低速、大扭矩、斷電自鎖等優點，因而在微型機械、機器人、精密儀器、家用電器、航天器、汽車等方面顯示出廣泛的應用前景。The surface rubbing technique has been commonly used for fabricating liquid crystal display panels by lcd industry. however, the rubbing process may cause electrostatic charge, dust or scratches that tend to destroy the display quality
然而在摩擦過程中會引起靜電、塵埃造成成品率下降，最嚴重的是摩擦產生的溝痕使微顯示器件的顯示質量降低。Ultrasonic motors are a new kind of solid actuators that come into being since 1980 ’ s, which use inverse piezoelectric effect of pzt to excite stator ’ s elliptical vibration and produce driving power by frictional coupling
超聲波馬達是上世紀80年代開始發展起來的一種新型驅動器，它是利用壓電陶瓷的逆壓電效應激勵出定子表面質點的橢圓軌跡振動，依靠摩擦耦合來實現驅動。This machine has great feeding ability, easy to be regulated, can be fed with fixed quantity under control of time delay relay ; it is divided into one - way feeding and bidirectional feeding in terms of feeding direction, suspending type and seating type in terms of installation ; in order to assure precision of feeding, roller encapsulation is equipped to increase frictional coefficient between adhesive belt and rollers ; the rectangle discharging mouth has large dimension which can prevent humping up materials ; this machine has close structure, reliable application and can be easily repaired because it has many similar parts with belt type conveyor
該機給料能力大，調節給料量方便，又可在時間繼電器的控制下定量給料按給料方向該機可分為單項給料和雙向給料，按安裝方式又分為吊掛式和座式為了保證給料的精度，主動滾筒包膠，以增加膠帶與主動滾筒的摩擦系數料倉矩形卸料口的尺寸大，物料不易起拱該機結構緊湊，使用可靠，它與帶式輸送機有許多通用部件，故維修方便。In large rotating machinery using filmatic bearing ( turbogenerator, air compressor, etc. ) there is a potential trouble from impefect installation or running conditions, a metals " contact between rotors and shells. the trouble is usully called rubbing. the advantage of ae technologe in the rubbing diagnosis and early detection is showed. instead of classical ae characteristic parameters ( counts, amplitude, energy, duration and the other ones ) a new feature extraction by frequency analysis of ae envelop signals is discussed. both research of ae process and field experements indicate that periodic components in the envelop spectrum related to rotational speed increase evidently at the beginning of rubbing production, hence are highly sensitive to the rubbing fault diagnosis. according to the new design an acoustic emission equipment for the rubbing diagnosis named buaa ae testing system is developed and described
汽輪發電機、空氣壓縮機等採用油膜支撐的大型轉動機械，由於安裝或運行中的原因，在轉子旋轉過程中，可能和器壁發生輕微的摩擦和碰擊，簡稱碰摩.聲發射技術在碰摩發生特別是故障早期診斷上有優越性.本系統的特點是沒有沿用傳統的計數、幅度、能量和持續時間等聲發射特性參數，而是在聲發射包絡信號的頻率分析中進行特徵提取.聲發射發生的過程分析和現場試驗都表明這種方法對碰摩檢測很敏感，在碰摩發生的起始階段，包絡譜中與轉速同步的周期性分量顯著增加.根據這種新的設計思想自行研製了buaa碰摩聲發射檢測儀並對此作了介紹分享友人
