RISReliability-Based Topology Optimization Using Mean-Value Second-Order Saddlepoint Approximation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A reliability-based topology optimization (RBTO) approach is presented using a new mean-value second-order saddlepoint approximation (MVSOSA) method to calculate the probability of failure. The topology optimizer uses a ...
Reliability Analysis Using Second-Order Saddlepoint Approximation and Mixture Distributions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes a new second-order saddlepoint approximation (SOSA) method for reliability analysis of nonlinear systems with correlated non-Gaussian and multimodal random variables. The proposed method overcomes the ...
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 ...
Collision-Avoidance Reliability Analysis of Automated Vehicle Based on Adaptive Surrogate Modeling
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a reliability analysis method for automated vehicles equipped with adaptive cruise control (ACC) and autonomous emergency braking (AEB) systems to avoid collision with an obstacle in front of the vehicle. ...
