RISDesign for Disassembly With High-Stiffness Heat-Reversible Locator-Snap Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent legislative and social pressures have driven manufacturers to consider effective part reuse and material recycling at the end of product life at the design stage. One of the key ...
Design Optimization of Vehicle Structures for Crashworthiness Using Equivalent Mechanism Approximations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new method for crashworthiness optimization of vehicle structures is presented, where an early design exploration is done by the optimization of an “equivalent” mechanism approximating a vehicle ...
Topology Optimization of Multicomponent Beam Structure via Decomposition-Based Assembly Synthesis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a method for synthesizing multicomponent beam structural assemblies with maximum structural performance and manufacturability. The problem is posed as a relaxation of ...
Decomposition-Based Assembly Synthesis for Structural Stiffness
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a method that systematically decomposes product geometry into a set of components considering the structural stiffness of the end product. A structure is represented as a ...
Decomposition-Based Assembly Synthesis of Space Frame Structures Using Joint Library
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a method for identifying the optimal designs of components and joints in the space frame body structures of passenger vehicles considering structural characteristics, ...
Three-Dimensional Assembly Synthesis for Robust Dimensional Integrity Based on Screw Theory
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a three-dimensional (3D) extension of our previous work on the synthesis of assemblies whose dimensional integrity is insensitive to the dimensional variations of individual ...
High-Stiffness, Lock-and-Key Heat-Reversible Locator-Snap Systems for the Design for Disassembly
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Driven by the moral sense of obligation, legislative and social pressures, manufacturers now consider effective part reuse and material recycling at the end of product life at the design stage. ...
Decomposition-Based Assembly Synthesis of a Three-Dimensional Body-in-White Model for Structural Stiffness
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an extension of our previous work on decomposition-based assembly synthesis for structural stiffness, where the three-dimensional finite element model of a vehicle body-in-white ...
A Co-Evolutionary Approach for Design Optimization via Ensembles of Surrogates With Application to Vehicle Crashworthiness
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In many engineering application, where accurate models require lengthy numerical computations, it is a common design practice to perform design of experiments (DOE) and construct surrogate models ...
Automated Vehicle Structural Crashworthiness Design via a Crash Mode Matching Algorithm
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an automated algorithm for the design of vehicle structures for crashworthiness based on the analyses of the structural crash mode (CM). The CM is the history of the ...
