vibration control

In this paper, we discuss two problems concerning scattering and localisation of flexural waves in structured elastic plates. Firstly, we compare the scattering amplitudes of waves in a thin plate, generated by a point source, due to a single mass and to a large number of smaller masses, having the same equivalent mass and located around a circle. We show that in the second case, the scattering can be reduced, in particular in the medium- and high-frequency regimes.

Abstract:

Three fully funded PhD positions are available in Dr. Lei Zuo's group in the department of mechanical engineering at Virginia Tech starting from Fall, 2016. One opening is about design and control of wave energy converter, one is on vibration energy harvesting fro oil drilling system and another one is about energy harvesting from backpack while human walking or running.

The position is still open for apply.



You will perform research and development work using active/passive vibration control measures to reduce vibration of typical offshore structures. You will also develop new

numerical models, new control algorithm, and optimize the locations of actuator/sensors.  



Requirements:



·               A PhD in Mechanical/Civil Engineering
