RISReliability Analysis of Nonlinear Vibratory Systems Under Non-Gaussian Loads
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A general methodology is presented for time-dependent reliability and random vibrations of nonlinear vibratory systems with random parameters excited by non-Gaussian loads. The approach is based on polynomial chaos expansion ...
Reliability Analysis of Nonlinear Vibratory Systems Under Non-Gaussian Loads Using a Sensitivity-Based Propagation of Moments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper proposes a new methodology for time-dependent reliability analysis of vibratory systems using a combination of a first-order, four-moment (FOFM) method and a non-Gaussian Karhunen–Loeve (NG-KL) expansion. The ...
