    實驗教學(xué)是高等學(xué)校理工科教學(xué)中的重要組成部分,因為實驗教學(xué)不僅僅是學(xué)生獲得知識的重要途徑,,而且對培養(yǎng)學(xué)生的綜合素質(zhì),、實際工作能力、科學(xué)研究能力和創(chuàng)新能力都具有十分重要的作用,。而液壓與氣壓傳動是機械類專業(yè)必修的專業(yè)基礎(chǔ)課,,是一門實踐性很強的課程,所以現(xiàn)代液壓教學(xué)不只是單純教授學(xué)生理論知識,,更應(yīng)加強學(xué)生實際動手能力的鍛煉,。( Z5 _0 s( ?6 Z  m( P1 u+ B

嘿嘿,,大哥,,這是四種控制方式啊,?,??哪里有六種,?額,,中文就有問題的話,,只能說明本人語言能力不行.....O(∩_∩)O哈哈~  發(fā)表于 2011-4-28 14:27
中文看起來就有問題。第一句可簡化為控制系統(tǒng)由PLC,、計算機控制,、手動、自動控制等方式組成,。是說控制系統(tǒng)有6種控制方式嗎,?  發(fā)表于 2011-4-28 11:53

# o+ x* K  S4 E(1)液壓實驗臺測試壓力較低、輸出流量比較小,。從成本和學(xué)生使用安全角度考慮,,目前實驗室內(nèi)的兩臺試驗臺,一臺壓力為15MPa左右,,另一臺最高壓力為22MPa左右,。變量泵液壓系統(tǒng)的最大輸出流量為32L/min,定量泵液壓系統(tǒng)的額定流量為12L/min,。. `! }7 l5 p  H3 o0 @- v3 p' Q6 P
2)現(xiàn)有液壓實驗臺可以做通用液壓元件的實驗,,卻不能滿足特殊液壓元件(如插裝閥和多路換向閥)的測試。

Out of consideration for the cost and students use safety ,,the two test bench in laboratory at present both have the characteristic of lower test pressure and small out flow.

/ \' c  Y4 }" L) Q  C5 a8 E    綜合上面兩個原因,如果想使液壓實驗技術(shù)和液壓技術(shù)的發(fā)展同步,,可以采取優(yōu)化現(xiàn)有液壓實驗臺的方法來實現(xiàn),。本文中,在參考YCS-DII電液伺服比例實驗臺的基礎(chǔ)上,,完成實驗臺優(yōu)化中增設(shè)液壓回路的設(shè)計,,完成優(yōu)化液壓實驗臺電氣系統(tǒng)并繪制出相應(yīng)的控制圖。通過仿真軟件AMESim的應(yīng)用,,為增設(shè)液壓回路建立仿真模型并設(shè)置參數(shù),,從而得到比較合理的液壓系統(tǒng)和比較理想的元件參數(shù)。! ~& |* P5 u& z4 O.

     Comprehensive considered  two reasons above,,if we want to creating a synchronous development of experiment and technology in hydraulic ,,we should optimize the existing hydraulic test bench. In this paper,have finished the design of hydraulic loop which are added in experimental platform optimization design in reference to the  YCS – DII  electro-hydraulic Servo proportion experimental platform.

Besides, the hydraulic and pneumatic transmission program is an Compulsory specialized fundamental course of Machinery specialized. So  modern hydraulic program should not only tell student theory knowledge, but also reinforce the students’ practical ability of exercise.個人觀點,,請參考,。
