With the development of the science and technology, fluid driving is used widely in more and more fields. The function test of hydraulic component is more frequent. The traditional hydraulic technology of test depends on the manual operation, and the way of data collection is sensor and simulation quadric meter. By this means, the factitious error is very serious in conclusion, lower efficiency and precision, and the test process is loaded down with trivial det--ls, not convenient. *ming at above-mentioned, according to the using demand, referring to interrelated nation and calling hydraulic test criteria, the dissertation designs a set of hydraulic compositive test bed, for the synchronous hydraulic system and the typical hydraulic components of double-bomb transport vehicle as test object.Based on the project of factory, the dissertation will do the design and research as follows:(1) The hydraulic system of test bed is designed according to the using demand and the test outline. *ming at the typical test circuit, the dissertation analyzes its designing idea and working principle.( 2 ) The dissertation brings forward a grade-pattern automatic control scheme of upper-computer & lower PLC, elaborates the compiling idea of the applied program of PLC control system, adopts programming way of pattern plate to do the applied program of upper computer based on VB. In order to assure the credibility of the test data from sensors in the process of collection and transmission, the sensor signal is compensated non-linearity and modified by upper computer, and the characteristic curve is bedecked.(3 ) In order to assure the test precision of the system, the dissertation goes on analyzing as follows: The paper builds the dynamics model of the valve-core movement and the mathematics model of hydraulic impact resulting from the movement of the valve-core. Through the simulation and analysis, the dissertation sets up the matching relation of precursor control pressure, action time, hydraulic impact, providing theory supporting for choosing difference control pressure under different test require. The dissertation sets up the data model of the precursor core of the pressure valve, analyzes its dynamic response performance under hydraulic impact, proves its good response characteristic. According to analyzing the localABSTRACTtest relation curve about the control electricity and the flow of the variable pump, it proves that the proportion adjusting performance of the variable system is very good.(4) The analysis results for the local test show that the hydraulic compositive test bed of double-bomb transport vehicle att--ns expected design purpose, and the precision grade att--ns C.
