Evaluation of System Evolvability Based on Usable Excess
(The American Society of Mechanical Engineers (ASME), 2016)Complex, largescale engineered systems are an integral part of modern society. The cost of these systems is often high, while their ability to react to emergent requirements can be low. This paper proposes evolvability, ... -
Position Space Based Compliant Mechanism Reconfiguration Approach and Its Application in the Reduction of Parasitic Motion
(The American Society of Mechanical Engineers (ASME), 2016)This paper introduces a positionspacebased reconfiguration (PSR) approach to the reconfiguration of compliant mechanisms. The PSR approach can be employed to reconstruct a compliant mechanism into many new compliant ... -
Gear Flank Modification Using a Variable Lead Grinding Worm Method on a Computer Numerical Control Gear Grinding Machine
(The American Society of Mechanical Engineers (ASME), 2016)Tooth crowning of a ground helical gear is usually done by adjusting the radial feed with respect to the axial feed of the grinding worm on the modern CNC gear grinding machine. However, when the amount of crowning and the ... -
Decomposition Based Design Optimization of Hybrid Electric Powertrain Architectures: Simultaneous Configuration and Sizing Design
(The American Society of Mechanical Engineers (ASME), 2016)Effective electrification of automotive vehicles requires designing the powertrain's configuration along with sizing its components for a particular vehicle type. Employing planetary gear (PG) systems in hybrid electric ... -
Part Worth Utilities of Gestalt Principles for Product Esthetics: A Case Study of a Bottle Silhouette
(The American Society of Mechanical Engineers (ASME), 2016)Reaching a balance between product form and function is one of the main challenges of design teams. When users make choices among products with similar functionality and price, esthetics becomes a decisive factor, and ... -
Excess Identification and Mapping in Engineered Systems
(The American Society of Mechanical Engineers (ASME), 2016)A system must continue to meet stakeholder needs throughout its service life to maintain value. Excess that is embedded into components during the design phase can enable inservice system evolution when new or changed ... -
On Global Convergence in Design Optimization Using the Particle Swarm Optimization Technique
(The American Society of Mechanical Engineers (ASME), 2016)The particle swarm optimization (PSO) method is becoming a popular optimizer within the mechanical design community because of its simplicity and ability to handle a wide variety of objective functions that characterize a ... -
Optimal Design of Vibrating Systems Through Partial Eigenstructure Assignment
(The American Society of Mechanical Engineers (ASME), 2016)This paper proposes an inverse structural modification method for eigenstructure assignment (EA), which allows to assign the desired mode shapes only at the parts of interest of the system. The presence of unimposed ... -
Topology Generation for Hybrid Electric Vehicle Architecture Design
