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
首先在流變學原理的基礎上,深入分析混凝土在輸送管道內的流動狀態,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,建立泵送迴路和分配迴路的數學模型,並運用模擬軟體matlab simulink對泵送和分配迴路模型進行了模擬,分析了在不同的輸入流量(泵送頻率)和換向時間下,活塞桿的位移和系統的液壓沖擊情況,找到了引起液壓沖擊的根本原因(即分配迴路的響應時間(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。The second chapter simply introduces the development of alternate asynchronous inverter technology and retrospects some types of energy - saving systems for hydraulic elevators. then the working principles of the project are discussed and analyzed at four different working status, i. e. light load upwards, heavy load upwards, light load downwards and heavy load downwards. and the chapter focus on the introduction of structure design of pump station, calculation and type selection of pump / motor reversible units, research on oil leakage principles of accumulator circuit, design of accumulator - pump / motor pressure - energy transformer and integrated valve blocks, etc. the last but not the least, the electrical wiring of vector inverter control cabin and design of computer control and data acquisition system are introduced
