Topology optimization of constrained layer damping structure under multi-constraints

摘要：

The topology optimization of structures with constrained layer damping was studied in this paper. The modal damping ratio weighting function was defined according to the character of dynamic. The sensitivity formula of the object function of the deleted elements and the corresponding flow of the optimization was introduced to optimize the modal damping ratio weighting function under certain frequency of the material quantity and structure of constrained damping. Finally, a numerical example demonstrates that the method used in this paper is effectively.
