Hydraulic system contaminate performance simulation and optimization design

This paper mainly describes optimization design for a kind of pollution control for hydraulic system. It is mainly used to improve the reliability and life expectancy of the hydraulic system. Through the analysis on the basis of the theory of hydraulic knowledge, and from all hydraulic components to the purification system application software simulation analysis, the optimization design of hydraulic cleaning system are obtained. Firstly, based on the derivation of hydraulic system pollution dynamic equation, the changing trends of solid particle concentration with time can be simulated by Matlab. Therefore the optimal time of completing purification can also be determined from the simulation result. Secondly according to the NASA-1638, turning different pollution levels into level 6, thus the optimal selection of parameters optimization setting and purify the critical time can be determined. Thirdly, from the angle of the pollution control, according to the simplified model of hydraulic cleaning system. Parameters of the filter and layout of the system are set by establishing model and simulation by HyPneu, Finally, an example will demonstrate the feasibility of the scheme. It is verified that this method can improve the efficiency of filtering and improve the service life and reliability of the system.
