This dissertation first analyzes the overlap measuring data of the syt - i measuring platform and comes to the conclusion that the measuring error caused by pressure change is as high as 7 . 27 % 本文對syt - i型測量臺的測量數(shù)據(jù)進行分析,得出壓力變化引起的測量誤差高達7 . 27 % 。
Based on this method , design the system oil circuit and constant - pressure hydraulic power station as well as the hydraulic manifold block , measuring platform , electrical cabinet and reclaiming oil tank 在此油源方案的基礎上,設計出測量系統(tǒng)油路、油源泵站系統(tǒng),同時進行了液壓集成塊、測量臺架、電氣控制柜和漏油回收油箱的設計。
During the performances of the syt - i servo valve overlap hydraulic measuring platform , the pressure difference between the exit and the entrance keeps changing , which causes comparatively great principle error in the measurement and affects the accuracy of the measuring system 在syt - i型伺服閥疊合量液動測量臺進行伺服閥疊合量的測量過程中,閥入出口壓力差變化給疊合量的測量帶入較大原理性誤差,影響了測量系統(tǒng)的精度。
Due to this , it is important to improve the hydraulic power system and enable it to control the pressure change at the measuring points of the servo valve , thus to develop the syt - ii servo valve overlap hydraulic measuring platform and improve the processing quality of servo valve 因而對其油源系統(tǒng)加以改進,使其能控制伺服閥測量口處壓力變化,進而開發(fā)出高精度的恒壓油源,研制出syt - ii型伺服閥疊合量液動測量臺,提高伺服閥的加工制造水平。
Through real - time , accurately and fast measuring and controlling of the parameters such as pressure , torsion and rotational speed , the system can calculate out the shim thickness needed with axial according to the size relations of measuring platform , display the shim ' s storehouse number and their parameters , draw the wave form trends as well as store and type the historical data 系統(tǒng)通過對壓力、轉速等參數(shù)實時、準確、快速的測控,根據(jù)基準測量平臺的尺寸關系能準確的計算出軸向所需的墊片厚度,并能實現(xiàn)系統(tǒng)所要求的墊片庫號及參數(shù)值實時顯示、波形動態(tài)繪制、歷史數(shù)據(jù)存儲和打印等功能。
