  1. Thirdly, it simulated the pumping circuit & dividing circuit with the widely used software matlab / simulink. the displacement of the rod piston and the impact of hydraulic are analyzed in the different input flow ( frequency of pump ) and different reversing time. it found out the cause of hydraulic impact ( one - to - one incorrespondence between the response time of dividing circuit and the operation time of rod piston ), and gave some methods to weaken hydraulic impact. in the final part of the paper, the reliability of the theory analysis is further verified by the experiment of hydraulic system

    首先在變學原理的基礎上,深入分析混凝土在輸送道內的動狀態,得出混凝土泵的負載特性方程;然後根據功率鍵合圖的建模方法,建立泵送迴和分配迴的數學模型,並運用模擬軟matlab simulink對泵送和分配迴模型進行了模擬,分析了在不同的輸入量(泵送頻率)和換向時間下,活塞桿的位移和系統的液壓情況,找到了引起液壓的根本原因(即分配迴的響應時間(固定值)與活塞桿的運動時間(變化值)不相匹配) ,並提出了相應的改進方法。
  2. The impact on the muffler performance is realized by the high - speed pulsation gas flow, which regenerates noises and strikes the acoustic elements of the muffler such as the pipe run, the body case and the separator plate to arouse the vibration radiated noise

    影響消聲器性能的主要原因是發動機排氣的高速脈動氣再生噪聲,其次是這種氣消聲器的、殼、隔板等聲學元件,進而激發振動輻射噪聲。
  3. Reactive power are calculated using the new algorithm. on the basis of analyzing different kinds of control strategies of var compensation, the paper applies the criterion of voltage and var to control switching and illustrates a improved mode of switching capacitor which can prevent the switched - capacitor from the impacting of instantaneous rush currents by means of zero - crossing triggering of scr components, and can realize auto - tracking var and auto - switching shunt capacitor bank. initial operating parameters are stored in information flash memory of the mcu using flash self - programming technique in order to decrease complexity of the circuit and improve stability

    高壓智能無功補償控制器以flash型16位單片機msp430f149為控制核心,採用了一種相角實時測量的新演算法,並在此基礎上計算出了功率因數、有功和無功,減少了運算量提高了精度;在分析了各種無功補償控制策略的基礎上,以母線電壓和無功功率復合判據控制投切,並提出一種改進的電容器投切方式? ?暫態投切控制晶閘過零觸發,避免了電容器投切時的電;穩態運行時接觸器替代晶閘,實現無功補償的自動跟蹤和電容器的自動投切,解決了投切時的暫態電和穩態時可靠運行的難題;控制器的原始運行參數採用flash自編程技術,將其保存在msp430f149片內的信息flash中,簡化了硬,大大提高了系統的可靠性。
