Modular Structural Component Design Using the Decomposition-based Assembly Synthesis
نویسندگان
چکیده
The design problem addressed in this study involves simultaneous optimization of two structures for the locations of joints and joint attributes (assembly synthesis), while investigating the possibility of sharing some of the components among two products (design for modularity). A genetic algorithm is employed for the solution of the problem. The objective function attempts to minimize the reduction of structural strength due to introduction of spotweld joints and maximize the manufacturability of the components. The method is applicable to 3-D beam-based structures, and a case study on automotive bodies is presented to demonstrate the capabilities of the developed software.

متن کاملModular Decomposition Method Based on Design Structure Matrix and Application
Modular decomposition is an effective means to achieve a complex system, but that of current part-component-based does not meet the needs of the positive development of the production. Design Structure Matrix (DSM) can simultaneously reflect the sequence, iteration, and feedback information, and express the parallel, sequential, and coupled relationship between DSM elements. This article, a mod...

∗ corresponding author ABSTRACT A method is presented for synthesizing multi-component structural assemblies with maximum structural performance and manufacturability. The problem is posed as a relaxation of decomposition-based assembly synthesis [1,2,3], where both topology and decomposition of a structure are regarded as variables over a ground structure with non-overlapping beams. A multi-ob...
متن کاملModular Distributed Models of Engineering Structures
Approaches to engineering design and manufacturing such as integrated design and manufacture and just in time fabrication depend on interaction with and among component supply companies that most often use very diverse technologies. The Internet Engineering Design Agents (i-EDA) software system uses a distributed, component-based, agent methodology that is realized following a strong black box ...
