The design of a recycled-carbon fiber–reinforced plastic/metal hybrid (PMH) engine cradle is realized via combined optimization techniques. Topology optimization (TO) and free-size optimization (FSO) techniques are exploited in the design process to find the optimal rib configuration and location of...
The paper presents an introductory overview of modeling techniques used by the authors for MDO–PD (MultiDisciplinary Optimization – Preliminary Design). The algorithms used by the authors in their MDO–PD code for modeling aerodynamics and aeroelasticity are reviewed. For the aerodynamic analysis, a...

Using the NDF approach, the most favorable structure for the optimization goal can be selected in three schemes: (1) adding bracings at unstable nodes, (2) removing unstable nodes and replacing short bars with long ones, or (3) selecting a new topology form to avoid containing unstable ...
This work develops a topological optimization framework for parametric lattice structure design under harmonic load based on the scale-dependent multiscale finite element method (MsFEM). Two different design variables are introduced and optimized simultaneously in the topology optimization, i.e., the con...
This paper takes the complex shell cylinder structures for example, optimizes the structures as a whole with multidisciplinary design optimization method. The complex structures contain grid stiffened structure, cone structure and rood beams which are made of composite materials and metal.Building the pa...
In this investigation, an Improved Collaborative Optimization (ICO) method based Multidisciplinary Design Optimization (MDO) framework for front structure of an electric car body-in-white (BIW) is presented. ICO method based on 1-norm and dynamic flabby coefficient, which shows relatively high efficie...
