Abstract EN
The performance of pulse-switching vibration control technique is investigated using a new method for switching sequence, in order to enhance the vibration damping.
The control law in this method which was developed in the field of piezoelectric damping is based on triggering the inverting switch on each extremum of the produced voltage (or displacement); however, its efficiency in the case of random excitation is arguable because of the local extremum detection process.
The new proposed method for switching sequence is only based on the fact that the triggering voltage level was determined using windowed statistical examination of the deflection signal.
Results for a cantilever beam excited by different excitation forces, such as stationary and nonstationary random samples, and pulse forces are presented.
A significant decrease in vibration energy and also the robustness of this method are demonstrated.
