报告摘要：Passive vibration control is widely used in engineering because of its high reliability and low cost. There are numerous passive vibration control strategies. Ours is assigning natural frequencies so that resonance can be avoided or assigning modes to influence how vibration may form. These are achieved through suitable structural modifications determined through inverse analysis. Our approach uses only a small number of measured receptances and in principle a theoretical model of the structure to be controlled is not needed. The solution of the required modifications become that of an optimisation problem. Other types of optimisation problems may be encountered in this vibration control methodology.

In this talk, our vibration control strategy and the concept of receptances are explained, the key challenges using this approach are highlighted and what can be achieved is demonstrated through several practical examples.
