پد میرایی با یک لایه محدود – کامسول

This model presents a method to analyze acoustic damping pads. These pads use a constrained layer of viscoelastic material to dissipate energy and thus reduce the energy radiated as noise. Damping pads are used in many different industries to reduce the noise generated by vibrating panels and offer a lightweight method to reduce noise in some applications.

The model analyses the difference between a untreated panel and one with an acoustic treatment. The model also shows results using the traditional approach of modeling the damping pads, as an additional mass and damping. It is seen that this traditional approach leads to inaccurate results when compared to a full multiphysics model.
