Vibration And Impact Induced Sound
(2010-10-22)Sound generated by impacting structures is of considerable importance in noise control. Sound is generated by a vibrating structure by inducing pressure fluctuations in the surrounding medium. Impact induced noise is the ... -
Vibration mitigation in spacecraft components using Stewart platform and particle impact damping
A spacecraft encounters two regimes of vibrations: launch loads and on-orbit loads. Both these loads propagate through the spacecraft structure, which is primarily made up of honeycomb sandwich. The launch loads that are ... -
Vibration Testing of Structures under Random Support Excitations
(2018-07-30)Vibration testing of structures constitutes a crucial step in design and commissioning of engineering structures. The focus here is on simulating field conditions in a laboratory so that detailed investigations of the ... -
Vibrational Energy Harvesting : Design, Performance and Scaling Analysis
