The Technology Research On The Hydraulic Computer Aided Test (CAT) Using In AGC Cylinder Test System

In the nearest decades, with the development of the theory and technology in each scientific field, hydraulic CAT system has changed greatly, and the hydraulic CAT (Computer Aided Test) systems based on virtual instruments have been developed constantly.AGC cylinder is one of the most important hydraulic components of the rolling line in the hot rolling and cold rolling factory in Panzhihua Iron and Steel Co. This paper utilizes hydraulic CAT technology to study the technology for developing the testing system of AGC cylinder according to the requests of the factual performance measurement of cylinder.In the development of the measure and control system of AGC cylinder, the development of the measure and control software is a very important link, the author adopts frequency and responds principle to analyze the theory of and method of the dynamic characteristic measurement, use dispersed mathematics and computer control theory to set up the mathematical model of its dynamic characteristic, and further investigate to testing the parameter , testing the data , method of testing etc., the error has been analyzed to the choice and sampling of sampling cycle.The thesis study on the simulation of the console of and control interface of and design of software and net of ACG measure by combining knowledge such as virtual instruments technology, automatic control theory, computer technology, choosing VC 6.0 as the software developing instrument.The AGC cylinder measure and control system developed passes experiment test and examine and comparison analysis, reaches the requirement with real project, improves production efficiency and measure precision, reduces the maintenance cost of the apparatus, and well solves the key technology problem in the hydraulic pressure measuring.
