Abstract

This paper addresses the design and application of active interfaces and semi-active vibration absorbers that can be used to reduce annoying vibration or noise levels. Currently, these devices are mainly used in automotive applications but they can easily be adapted to meet the requirements of aerospace applications. The design process and the numerical simulations that are necessary to assess the performance of such active interfaces are described. This includes the modeling of the mechanical structure, of the components of the active interface, and of the controller. The simulation results are compared with experimental measurement results, which agree very well. An application example is presented as well. Finally, the design, application, and effect of a semi-active vibration absorber are described.
