This thesis analyzes all kinds of throttle components, points out the advantage of adapting eev, and analyzes the start - up and the discharge characteristics of eev, and dynamic response of refrigeration systems when the opening degree of eev is changed, etc. eev is placed into a tumoff position while the unit starts up, and after being kept for a period of time it is placed into a bigger position, after some more time it is put into a basic control
本文對比分析了冷藏箱製冷系統各種節流元件的特點，指出電子膨脹閥應用的優勢，同時分析了電子膨脹閥的啟動特性、流量特性以及系統在閥開度變化時的動態響應。電子膨脹閥在啟動時應先使電子膨脹閥處于關閉位置，延時一段時間后，再將閥開至一個較大的位置，再延時一段時間后轉移到基本的控制。Firstly, the relationship of atomic force and distance is studied. the scan type of samples and the working mode of probe is confirmed, then pzt is chosen as actuator for micro scan displacement, and optical deflexion method is used to detect the deflexion value of cantilever. after all these work, the system light path design is finished, and its mathematical model is completed
首先，分析了原子力探針系統的中原子力?距離的關系，並確定探針系統的探針的工作模式和樣品的掃描模式，從而選擇壓電陶瓷作為掃描微位移驅動器;採用光學偏轉法檢測微懸臂偏轉量，並選用了psd作為傳感元件，並在此基礎上進行了系統光路設計及其數學模型的建立。A permanent magnet synchronous motor is selected so that the system could work excellently. multiform measures are taken to weakening the torque ripple, such as adopting stator - flume, choosing right ratio of magnet - width and slot - width, and programming properly. a permanent magnet synchronous motor cad software is worked out for predigesting the design of the motor
力矩脈動是衡量交流伺服系統性能優劣的重要指標，為達到理想的控制效果，系統採用正弦波驅動的稀土永磁同步電動機作為執行元件，電機本體的設計綜合採用定子斜槽、將轉子永磁體連續移位、合理選擇永磁體寬度和齒槽寬度比等方法，基本消除了齒槽轉矩；對于紋波轉矩，系統採用軟體的方式加以削弱和補償。The disease in jaw surface will be drop the bite force ; the bite force in the patient who disease in temporal jaw joint descent obviously than normal person ; serious mistake in join deformity, the acute damage in the area arthritis can also drop the bite force evidently ; compare to normal children, wenneberg fund that the bite force lower and the duration of the biggest bite force shorter in the children who fall ill of the chronic arthritis ; the bite force also be used in appraise of the recovery condition in surgical operation 、 disorder in jaw arthritis and the serious bone offset in bite lopsided etc. some materials, it will be produce polarization phenomenon inside when suffered some force in certain direction, at the same time, it produce opposite electric charge in two of the surface ; and resume to the station of on - electrification when removed the outside force ; change the direction of the outside force, the polarity of the electric charge also be changed, this kind of phenomenon is called as “ piezoelectric effect ”
本文設計了石英晶體壓電傳感器，以它作為傳感元件把咬合力信號轉變成電信號;利用ts5860型準靜態電荷放大器把傳感器的電荷信號轉變成電壓信號;選用usb7822數據採集卡，編寫該數據採集卡的驅動程序，採集該電壓信號並送到計算機里;編寫labview程序對該信號進行處理，得出咬合力值和咬合力曲線，並把測量結果以電子表格的形式保存，以便做進一步的分析和研究。通過對該測量儀的靜態標定、動態標定、溫度漂移標定以及實際測量試驗，證實了本測量儀具有較高的靈敏度、受動態力和溫度變化的影響比較小、能實時地顯示咬合力曲線和較準確地顯示咬合力值，滿足了咬合力測量的要求。分享友人
