Abstract

Abstract:

Aiming at the uncertainty of internal leakage for spool valve couple at zero position effected by the size parameters perturbation， a mathematical model of internal leakage at zero position considering parameter perturbation is established. Then， the distribution characteristics of internal leakage at zero position under the perturbation of size parameters are obtained. Furthermore， a Kriging surrogate model of the mapping relationship between process parameters and distribution characteristic parameters of internal leakage at zero position is established. Based on the Kriging surrogate model， the global sensitivity analysis of distribution characteristic of internal leakage at zero position to process parameters is carried out by Sobol method， which can provide a theoretical support for reducing internal leakage and improving consistency. The results show that the internal leakage at zero position under the size parameters perturbation obeys normal distribution law. Influence of the interaction among process parameters on the distribution characteristics can be ignored. Compared with the axial size process parameters， distribution characteristics are more sensitive to the variation of radial size process parameters and throttling edge corner radius process parameters. Minimum radial clearance of spool valve couple has the greatest influence on the average value of internal leakage at zero position， while the maximum corner radius of throttle edge of spool has the greatest influence on the consistency of internal leakage at zero position. Experimental values of the internal leakage at zero position of spool valve couple present a certain fluctuation， which is consistent with the overall prediction trend of the theoretical model.

Key words: spool valve couple, leakage at zero position, distribution model, sensitivity analysis, process parameters
