Abstract:: The Solid Isotropic Material with Penalization (SIMP) was applied to establish the topology optimization model of constrained layer damping (CLD) structure.The minimum of displacement response was considered as the objective function and the volume fraction of constrained layer damping material as constrained conditions.The sensitivity of modal damping ratio was introduced in the sensitivity analysis of the objective function,making the sensitivity more accurate and sensible.The topology optimization model was solved by Method of Moving Asymptotes (MMA).The numerical examples demonstrated that the proposed dynamics optimization of CLD structure was of validity and effectiveness.
