Transverse Vibrations of Rotating Prismatic Beams Produced by Variable-materials
Transverse vibration Natural frequency Variable material Rotating beam
2009/10/13
In this study, transverse vibrations of rotating prismatic beams based on variable materials are investigated.Natural frequencies are obtained by the Rayleigh-Ritz method. These results are compared w...
Fuzzy Logic Control of Vibrations of Analytical Multi-Degree-of- Freedom Structural Systems
Fuzzy logic control PD control Multi-degree-of-freedom structure Earthquake-induced vibratio
2009/10/12
A fuzzy-logic-based controller and a PD controller are designed for an active control device considering a multi-degree-of-freedom analytical structure against earthquakes. The advantage of the fuzzy ...
Analysis of Viaduct Road Vibrations Using Cluster Filtering and Actuation
Distributed-parameter structures Spillover e ect Cluster fltering and actuation
2009/10/12
An infinite number of modes of distributed-parameter structures cause spillover destabilization creating problems in controlling vibrations. This paper introduces cluster filtering and actuation in th...
EXPERIMENTAL AND NUMERICAL STUDIES ON STEEL PENSTOCK VIBRATIONS CAUSED BY PRESSURE PULSATIONS
steel penstock pressure pulsation vibration test numerical analysis design standard
2008/12/25
In our previous paper, we described vibrations with circumferential mode number n = 2 when a frequency of a pressure pulsation in a turbine coincides with the natural frequency of a steel penstock. W...
