| description | 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,
where both topology and decomposition of a structure are regarded as variables
over a ground structure with nonoverlapping beams. A multiobjective genetic
algorithm with graph-based crossover, coupled with FEM analyses, is used to
obtain Pareto optimal solutions to this problem, exhibiting trade-offs among
structural stiffness, total weight, component manufacturability (size and
simplicity), and the number of joints. Case studies with a cantilever and a
simplified automotive floor frame are presented, and representative designs in
the Pareto front are examined for the trade-offs among the multiple criteria. |
