This video shows a simulation of a damped structure with two independent masses located inside the structure. This study has been done to analyzed the damping effects of spring-dampers located in different position on the structures under a shock of about 80g.
The structure and dampers replied very well to the shock, the FEA calculated correctly the displacement and acceleration of the structure keeping the stress within allowable stress.
A second analysis has been performed to study the frequency responce of the structure under typical horizzontal load, the video is at the following link:
