Abstract:The antiskid valve is a key part in the antiskid braking system. At present, the comprehensive research on the dynamic characteristics of antiskid valves is relatively missing. Especially, the simulation results and test results cannot be unified. Firstly, a simulation model of antiskid valve based on MATLAB/Simulink software is formulated. The simulation curve of antiskid valve dynamic characteristics is obtained. Secondly, the dynamic characteristics test of the antiskid valve is achieved according to the data acquisition technology and the pneumatic control technology. In this way, the detection of dynamic characteristics is realized. The correctness of the simulation model and the reliability of the detection system are interactively verified with the highly fitted simulation curve and experimental curve. Finally, to comprehensively analyze the influence of relevant parameters on the dynamic characteristics, the saliency analysis theory and the regression analysis theory are utilized. The response surface method is used to complete the mathematical analysis of the experimental parameters and the dynamic characteristics. Experimental results show that the effect determination coefficients R2 are 0999 9 and 0996 7, the correction determination coefficients R2adj are 0998 5 and 0995 2, and the prediction determination coefficients R2pre are 0997 7 and 0992 7. These numerical values verify the rationality of the experiment design, which provide a reasonable and feasible method for optimizing the structure of the antiskid valve.
