Structural damping using nonlinear dampers (NES)

We start by summarizing noise and vibration problematics.Then available modeling tools are presented: materials and sub-structures, absorption, isolation, damping and encapsulation.Concerning vibrations, emphasis is put on structural damping: decoupling pads, viscous damping, Tuned mass dampers and Non-linear energy sinks. These solutions are compared in terms of pro and cons.
