Mechanical Vibrations and Vibration Control

1994
In these lectures, an introduction is given into the basic concepts of the theory of active and passive vibration damping. First one degree of freedom systems are discussed with respect to the different solution techniques and with view to damping and isolation mechanisms.

Vibration Controller of Marine Electromagnetic Vibrator

2009 International Conference on Measuring Technology and Mechatronics Automation, 2009
Marine electromagnetic vibrator is a non-explosive seismic source, for high resolution detection of marine seismic exploration ?which used sublevel sweep mode of marine electromagnetic vibrator. The vibration controller provides sublevel Chirp signal by marine geology condition. The Chirp signal was sent to exciter through power amplifier.

Design and control of a vibrating gyroscope

Proceedings of the 2004 American Control Conference, 2004
This work presents design and control of a vibrating gyroscope. The MEMS based device has been designed in the Pro-E environment and simulated in a finite element domain in order to approximate its dynamic characteristics with a lumped model. The device is a modified version of the existing MEMS gyroscope proposed in Yoichi, M, et al. (2000).

Vibration Analysis vs. Vibration Control

SAE Technical Paper Series, 2005
<div class="htmlview paragraph">Car manufacturing companies and their suppliers allocate significant human and financial resources to NVH-related R&amp;D. While the most advanced instrumentation and analytical techniques are used for these activities, the incremental improvements of NVH are rather small due to extreme complexity of the ...

Vibration control by confinement of vibration energy

The Journal of the Acoustical Society of America, 2005
A method for controlling vibration energy in a structure having a vibrating member using a vibration confinement device is provided. The vibrating member has boundaries and vibrates relative to the boundaries. The method includes selecting a vibration confinement region in the vibrating member relative to the boundaries.

On Optimal Control of the Vibrating String

SIAM Journal on Control, 1969
The paper under discussion refines some work done by the reviewer [SIAM J. Control 4, 276--294 (1966; Zbl 0166.35805)]. It is concerned with control of the vibrating string, represented by the partial differential equation \[ \rho \frac{\partial^{2} w}{\partial t^{2}}-\tau \frac{\partial^{2} w}{\partial x^{2}}=0, \quad 0 \leq x \leq l, \quad 0 \leq t ...
