Double-proof Car Test Bed Hydraulic Control Program Coordination, Design And Test

With the development of the science and technology, fluid driving is used widely in more and more fields. The function text 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 details and being inconvenient for analization. Aiming 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 has done the following the design and research:(1) Based on the interrelated hydraulic test criteria, the hydraulic system of test bed is designed according to the required demand of the user.(2) Aiming at the difference test item and content, the dissertation chooses some representative typical test circuit to analyze and discuss, and shows the compositive multi-function capability.(3) The analysis results for the local test show that the structure of the bed is logical, the operation is simple and reliable, and the test bed can achieve the function test of the synchronous hydraulic system and the typical hydraulic components, and the precision grade attains C, which satisfies the required demand of user.
