An Alternative Formulation of Collaborative Optimization Based on Geometric Analysis
(The American Society of Mechanical Engineers (ASME), 2011)Collaborative optimization (CO) is a multidisciplinary design optimization (MDO) method with bilevel computational structure, which decomposes the original optimization problem into one system-level ... -
On the Design of Interference-Fitted and Adhesively Bonded Joints for Lightweight Structures
(The American Society of Mechanical Engineers (ASME), 2011)Interference-fitted and adhesively bonded joints are hybrid fastening systems that involve a hub (cylindrical or asymmetric) and a shaft (solid or hollow) locked together by both a frictional ... -
Constraint-Based Limb Synthesis and Mobility-Change-Aimed Mechanism Construction
(The American Society of Mechanical Engineers (ASME), 2011)This paper proposes a new synthesis approach by using constraints for limb synthesis to target mobility-change in the mechanism construction. The limbs therefore produced have the facility to ... -
Joint Probability Formulation for Multiobjective Optimization Under Uncertainty
(The American Society of Mechanical Engineers (ASME), 2011)This paper presents a new approach to solve multiobjective optimization problems under uncertainty. Unlike the existing state-of-the-art, where means/variances of the objectives are used to ensure ... -
The Instantaneous Efficiency of Epicyclic Gears in Flight Control Systems
