Abstract
This research focuses on the establishment of a constructive solid geometrybased topology optimization CSGTOM technique for the design of compliant structure and mechanism The novelty of the method lies in handling voids nondesign constraints and irregular boundary shapes of the design domain which are critical for any structural optimization One of the most popular models of multiobjective genetic algorithm nondominated sorting genetic algorithm is used as the optimization tool due to its ample applicability in a wide variety of problems and flexibility in providing nondominated solutions The CSGTOM technique has been successfully applied for 2D topology optimization of compliant mechanisms and subsequently extended to 3D cases For handling these cases a new software framework involving optimization routine for geometry and mesh generation with FEA solver has been developed The efficacy of the approach has been demonstrated for 2D and 3D geometries and also compared with state of the art techniques
