Abstract EN
This paper deals with an optimal layout design of the constrained layer damping (CLD) treatment of vibrating structures subjected to stationary random excitation.
The root mean square (RMS) of random response is defined as the objective function as it can be used to represent the vibration level in practice.
To circumvent the computationally expensive sensitivity analysis, an efficient optimization procedure integrating the pseudoexcitation method (PEM) and the double complex modal superposition method is introduced into the dynamic topology optimization.
The optimal layout of CLD treatment is obtained by using the method of moving asymptote (MMA).
Numerical examples are given to demonstrate the validity of the proposed optimization procedure.
The results show that the optimized CLD layouts can effectively reduce the vibration response of the structures subjected to stationary random excitation.
