Synthesis of Optimal Shape and Topology of Structures

摘要: In this paper, a method is proposed for the design optimization of structural components where both shape and topology are optimized. The boundaries structure represented using contours density function. contour function corresponding to threshold value defined as boundary shape. over feasible domain by continuous piece-wise interpolation finite elements used analysis. values at nodes serve variables problem. advantage representation that can be modified optimized algorithm. Unlike previous methods optimization, material not modeled porous or composite homogenization method. Instead properties assumed depend on many approximate property-density relations have been studied. with objective minimizing compliance subject constraint total mass structure.
