Rule- Based Expert System as a Decision Support Tool in the Analysis of the Impact of Vibrations on a Microhydraulic Valve

There is a relationship between design and operational parameters in the context of the influence of vibrations on the operation of micro-hydraulic components. The analysis of the author's and co-author's research work to date indicates the need to carry out research related to determining the influence of structural parameters, i.e. valve seat diameter, type and stiffness of the spring, different design of the side slope of the cone of the closing element, and operational parameters, i.e. flow rate, operating pressures, on the frequency of external mechanical vibrations acting on the microvalve. Previous analyses have been carried out using the method of multi- valued logic trees, and induction trees, which have tentatively determined the rank of importance of design parameters on pressure pulsations during the occurrence of external mechanical vibrations. For a comprehensive analysis, it was decided to use a rule-based expert system (BrES) as a decision support tool.
