| Abstract: | The experimental modal analysis of the apparatus cabin of CZ 3a launch vehicle is performed firstly.In response of the dynamic characteristics of the apparatus cabin the hybrid vibration control for instrument board of apparatus cabin is experimentally performed by applying controllable constrained layer damping.Research results show it is very effective that applying the controllable constrained layer damping suppresses the vibration of the apparatus cabin of the launch vehicle. |
