An Efficient Polynomial Chaos Method for Stiffness Analysis of Air Spring Considering Uncertainties

open access: yesComplexity, 2021
Traditional methods for stiffness analysis of the air spring are based on deterministic assumption that the parameters are fixed. However, uncertainties have widely existed, and the mechanic property of the air spring is very sensitive to these ...

Time-Dependent Reliability-Based Design Optimization Utilizing Nonintrusive Polynomial Chaos

open access: yesJournal of Applied Mathematics, 2013
Time-dependent reliability-based design optimization (RBDO) has been acknowledged as an advance optimization methodology since it accounts for time-varying stochastic nature of systems. This paper proposes a time-dependent RBDO method considering both of
