Abstract
This work provides novel insights into the uncertainty quantification and reliability sensitivity analysis of a direct-operated relief valve undergoing vibration. A reliability model for pressure tolerance failure of the relief valve is developed based on the criterion that the pressure tolerance exceeded the allowable value, incorporating the vibration and multiparameter uncertainty. The Simulink simulation is employed to analyze the nonlinear behaviors of the valve. To avoid excessive nonlinear calculations, a Kriging-based strategy is adopted for reliability sensitivity analysis, allowing for rapid estimation of nonlinear responses. The results are compared with those obtained by MCS to verify the performance of the proposed method. The sensitivity results indicate that the proposed method saves 98 % of computational time without much loss of accuracy. Furthermore, more attention should be paid to the spring stiffness, valve element mass, and controlled chamber volume in the structural reliability design of relief valves.
期刊介绍:
The aim of the Journal of Mechanical Science and Technology is to provide an international forum for the publication and dissemination of original work that contributes to the understanding of the main and related disciplines of mechanical engineering, either empirical or theoretical. The Journal covers the whole spectrum of mechanical engineering, which includes, but is not limited to, Materials and Design Engineering, Production Engineering and Fusion Technology, Dynamics, Vibration and Control, Thermal Engineering and Fluids Engineering.
Manuscripts may fall into several categories including full articles, solicited reviews or commentary, and unsolicited reviews or commentary related to the core of mechanical engineering.
