  1. Comparing and analyzing the synchronous control strategy, which brings up the new method to control the double un - symmetry jars proceed synchronously with the combination of proportional valve and servo valve, which forms closed loop control ; basing on the above methods, models are made to get mathematics models of position control system and to analyze system model theoretically by using pid controller, we can realize regulating parameters, minimizing synchronous errors and enhancing the dynamic performances ; the simulink tool box in matlab software is used to imitate the system according to the model, which not only makes the result visual and easy to adjust the parameters in interactive way but also lets us understand the effects of different parameters and optimizes the dynamic properties. the theory of plc control in dshp is discussed after advanced understanding of the system movements. hardware design and general regulation are given on the base of siemens company products s7 - 200 plc

    本文根據大量的國內外文獻,對研配液壓機的工作原理及設計結構進了簡介;對位置同步的控制方法進了比較分析,提出比閥和伺服閥復合控制的環結構來對非對稱雙缸進同步控制電液比同步控制方案;在此基礎上著重對比閥控非對稱缸建模,最後得到位置控制系統的總體數學模,從理論上對同步系統動態特性進了分析,並用pid控制器進參數整定,減小雙缸同步誤差、提高系統的動態響應性能;其中控制性能的分析藉助于matlab軟體中的simulink工具箱,由已建立的數學模形成模擬模,得到可視化的模擬結果,從而利於交互方式下調整參數,了解不同的參數對系統的影響,優化同步系統的動態性能;在深入了解系統的動作特性后,對plc控制研配液壓機的原理進了探討,針對siemens公司s7 ? 200plc給出了硬體設計的總體規劃,編制出研配液壓機動作控製,在編中著重研究位移傳感器與plc的通訊、雙缸同步運的pid控制在plc上的實現及bcd碼撥盤輸入的植入問題。
  2. Then a laplace equation can be deduced and through computation, the blade profile coordinates and geometry of the cascade result from an analytical solution. next, an optimization method, taking the geometry parameters of the unclosed profile as its objective functions, is used to obtain an optimized blade profile. and last, the optimized profile is refined with round arcs added in the leading and trailing edges

    本文採用的勢、流函數解析法法中,將無旋方用新的類無旋方替代,這樣在計算域上得出速度場的解析關系式,計算得出初始葉;然後以此初始葉的幾何參數,如前尾緣的封度和葉彎角等為目標函數,通過優化對初始速度進自動調節直到目標函數值最小為止。
