Description
Summary:Valves are susceptible to fatigue fractures, long response times, and excessive leakages due to various influencing factors, directly impacting their safety and reliability. This study investigates the random uncertainties associated with performance and potential failure factors in a shifting hydraulic valve. It introduces an integrated analytical approach that combines the Monte Carlo method with uncertainty analysis, addressing both performance and potential failure considerations in reliability optimization design. The results obtained through the proposed method indicate that the reliability of the entire valve can reach 99.92%. This is a significant improvement of 65.49% compared to optimizing solely for performance and a 2.22 % increase compared to focusing solely on potential failure mitigation. The proposed method provides an effective approach for achieving optimal valve reliability design.
