Abstract
In this paper the computational methodology for evaluating vibro-isolation properties of the vibration reduction systems is discussed. The proposed procedure supports selecting the non-linear dynamic behaviour of passive systems and helps to perform the controller synthesis of active systems. Primarily, the mathematical model of a vibration reduction system is developed for the purpose of simulating its dynamic behaviour under different operating conditions. In the next step, the selected vibro-isolation criteria are determined numerically that are related to the opposed requirements of modern vibration reduction systems. Finally, an application of the Pareto-optimal approach is employed to find a trade-off regarding the high efficiency of vibration attenuation at the lowest suspension travel.
