Hydraulic piston pumps are commonly used in aircraft. In order to improve the viability of aircraft and energy efficiency, intelligent variable pressure pump systems have been hydraulic more widely. Efficient fault diagnosis plays an important role improving reliability performance systems. this paper, a method system (IHPS) based on nonlinear unknown input observer (NUIO) is proposed. Different from factors full-order Luenberger-type observer, IHPS considered NUIO. Firstly, new type...
An accurate estimation of the remaining useful life (RUL) not only contributes to an effective application aviation piston pump, but also meets necessity condition based maintenance (CBM). For current RUL evaluation methods, a model-based method is inappropriate for degradation process pump due difficulties modeling, while data-based rarely presents high-accuracy prediction in long period time. In this work, adaptive-order particle filter (AOPF) prognostic proposed aiming at improving...
Abstract As a key aircraft component, hydraulic piston pumps must be developed with high reliability. However, collecting failure time data of such for reliability analysis is big challenge. To save testing time, performance degradation obtained from tests can used quick estimation pumps. This paper proposes an engineering‐driven method considering the nature mechanical wear First, mechanism type pump investigated. By taking into account close relationship between rate and mechanism, inverse...
The precipitation of dissolved gas in oil is a challenging problem pollution control hydraulic systems. When the self-excited oscillation jet formed, there are two low-pressure regions cavity, and reduction pressure causes to precipitate out. Here, we investigated effect cavity on dissolution oil. We studied performance by simulating velocity fields inside under different ratios dimensionless structure parameters. results indicated that parameter intervals for maintaining good were...
