Inverse Problems and Global Optimization of the Oscillatory Systems
Most of the known methods of structural optimization involve local optimization, i.e., the determination of optimal parameters for the system with specified configuration, or local modification of this configuration [1,2]. In this paper, an approach is presented for global optimization of linear mechanical oscillatory systems using the inverse problem solution for the system with given frequency response. The optimization is conducted in the function space of frequency responses rather than in the system parameters domain. The connection between the two domains is provided by the solution of the inverse problem.
With this approach, the limiting performance of the linear multi-degrees-of-freedom vibration isolation systems is investigated and the procedure for the determination of optimal configuration and parameters is developed.
