Reliability‐Based Multidisciplinary Design Optimization under Correlated Uncertainties [PDF]
Mathematical Problems in Engineering, 2017 Complex mechanical system is usually composed of several subsystems, which are often coupled with each other. Reliability‐based multidisciplinary design optimization (RBMDO) is an efficient method to design such complex system under uncertainties. However, the present RBMDO methods ignored the correlations between uncertainties.

Multifidelity Multidisciplinary Whole-Engine Thermomechanical Design Optimization [PDF]
Journal of Propulsion and Power, 2014 Traditionally, the optimization of a turbomachinery engine casing for tip clearance has involved either two-dimensional transient thermomechanical simulations or three-dimensional mechanical simulations. This paper illustrates that three-dimensional transient whole-engine thermomechanical simulations can be used within tip clearance optimizations and ...
