Therefore , to test servovalve become an important work for improving control system ' s characteristic in chapter one , the work ' s origin and computer ' s applications in the hydraulic test ' s fields are showed , and the same product ' s position at present is briefly introduced . in chapter two , the basic characteristics of the eledtrohydraulic servovalve and the basic test methods are introduced 伺服閥的檢測對于保證伺服閥的性能指標、保證電液伺服系統準確快速穩定的工作有重要的意義論文主要闡述了以工控機、數據采集卡、信號發生器等硬件為基礎,運用虛擬儀器的思想,開發電液伺服閥計算機輔助測試系統的過程、收獲和最后取得的成果。

Aiming at several representative electric - hydraulic control module of the construction machine control system based on the can bus will stand out all the electric - hydraulic control system of the construction machine . based on what we have said above , we design the communication adapter , data acquisition module , data control module and the hydraulic test flat which is controlled by the high - speed switch valve 針對工程機械幾種典型的電液控制模塊,分析其功能需求,并探討了其實現的控制方式、控制復雜程度和數據傳輸和處理的量,經過縱橫向比選后,認為基于can - bus的數字電液控制系統必將成為下一代工程機械電液控制的主流。

Two methods “ principle of three dimensional stress determination developed from the above four basic ones by yangtze river scientific research institute are presented , one based on hydraulic fracturing and hydraulic tests on preexistent fractures in single borehole , another one based on ckx - 97 hollow package 3 direction strain gauge 并對長江科學院完善的單鉆孔中水壓致裂法三維地應力測量和ckx - 97型空心包體式鉆孔三向應變計的三維地應力測量的計算公式作了推導。

At first the design scheme of the test system of electro - hydraulic servo valve based on virtual instrument was proposed . according to this design scheme , the hydraulic test unit and measurement unit were developed 本文首先在介紹電液伺服閥特性和測試遠離以及虛擬儀器技術的基礎上,提出了基于虛擬儀器的電液伺服閥測試系統設計方案,以此方案研制了測試系統的液壓試驗單元和測控單元。

The structure arrangement of the intake tower for the underground hydropower station of baise project is suit to the complex topography and geology condition , and the hydraulic test shown that the flow pattern entering the tower is well 百色水利樞紐地下水電站進水塔結構布置,較好地適應了地基復雜的地形地質條件,水流流態良好。

No , corrosion was observed on the submerged production pump after its return on the surface , nor in the production pipes which were shown , for the statements of the hydraulic testing manager , surprisingly easy to dissemble 水利測試經理難掩驚訝地說,在將潛水生產泵拉回地面時,發現無腐蝕狀況,而生產管線也沒有出現腐蝕。

Chapter four introduces the implementation of other signal processing software based on the signal processing software platform . it also takes the computer - aided hydraulic testing software system as an example 第四章以液壓計算機輔助測試系統為列,講述了如何在信號分析軟件平臺的基礎上實現其它具體的信號分析系統。
