An efficient approach for reliability-based topology optimization

Engineering Optimization, 2015
This article presents an efficient approach for reliability-based topology optimization (RBTO) in which the computational effort involved in solving the RBTO problem is equivalent to that of solving a deterministic topology optimization (DTO) problem. The methodology presented is built upon the bidirectional evolutionary structural optimization (BESO ...

Reliability-based topology optimization for electromagnetic systems

COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2004
This paper presents a probabilistic optimal design for electromagnetic systems. A 2D magnetostatic finite element model is constructed for a reliability-based topology optimization (RBTO). Permeability, coercive force, and applied current density are considered as uncertain variables.

Reliability-based topology optimization of continuous structures

2008 7th World Congress on Intelligent Control and Automation, 2008
A new structural topology algorithm based on reliability is proposed. Moreover, the mathematical model of topology optimization based on the reliability for continuous structures is developed, in which the level set function is taken as design variables, minimization of the compliance is taken as objective function, reliability constraint is included ...

Reliability-based topology optimization considering corrosion

2012 Proceedings Annual Reliability and Maintainability Symposium, 2012
Mechanical engineers always expect to design a structure which could work properly in its whole lifetime. But there exist many random factors, such as dimension, material property and applied forces. Hence structures based on determinate design could fail with high probability.

Reliability‐based topology optimization of structures under stress constraints

International Journal for Numerical Methods in Engineering, 2018
SummaryIn this paper, we propose an approach for reliability‐based design optimization where a structure of minimum weight subject to reliability constraints on the effective stresses is sought. The reliability‐based topology optimization problem is formulated by using the performance measure approach, and the sequential optimization and reliability ...

Reliability-Based Topology Optimization of Laser Scanned Model

10th AIAA/ISSMO Multidisciplinary Analysis and Optimization Conference, 2004
Recent engineering process requires fast development and manufacturing of the products. This paper mainly discusses the process of rapid product development (RPD) from the reverse engineering to the optimal design. A laser scanning system scans a product and the efficient data processing method reduces the scanned point data.
