A novel multiobjective topology optimization method for suppressing vibration

To improve the dynamic characteristics of structures, an optimum method is to obtain the best dynamic topology structure without an additional dynamic absorber or actuator. This paper presents an ESO-SIMP multiobjective optimization methodology to solve the problem caused by an external excitation. In this approach, sensitivity filtering technique is introduced to eliminate the numerical instability phenomena. A two sides clamped plate is chosen as the numerical experiment model. Both static and dynamic characteristics are analyzed by using a compromise programming approach in topology optimization. The numerical simulation results validate the proposed methodology.
