... actuators forced vibration laminated composite plates piezoelectric materials sensors Laminated composite structures are very commonly used in various industries because of their high strength to weight ratio. Many researchers have investigated composite material structures in the past...

... limitations of many commercial piezoelectric accelerometers. To alleviate this difficulty, we present a low-frequency resonance accelerometer to capture extremely low speed rolling bearing faults. The design details are reported in this paper. With this new sensor, the resonance demodulation technique can...

...Xianmin Zhang; Arthur G. Erdman The optimal placement of sensors and actuators in active vibration control of flexible linkage mechanisms is studied. First, the vibration control model of the flexible mechanism is introduced. Second, based on the concept of the controllability and the observability...

...S. M. Yang; G. J. Sheu It has been stated that a uniform rotating shaft in the Rayleigh beam model has only a finite number of critical speeds and precession modes. This paper presents a controller design of optimal sensor/actuator location and feedback gain for steady state unbalance response...

...Senthil S. Vel; Brian P. Baillargeon An analytical solution is presented for the static deformation and steady-state vibration of simply supported hybrid cylindrical shells consisting of fiber-reinforced layers with embedded piezoelectric shear sensors and actuators. The piezoelectric shear...

.... This paper shows that the volume displacement of a vibrating beam can be measured through the use of a set of localized PVDF sensors each spanning only an area of interest. Summation of the volume displacements measured by these sensors would yield the total beam volume displacement. In this application...

...Marcellin B. Zahui; James W. Kamman; Koorosh Naghshineh Further development of local volume displacement sensors is presented. This development supports the implementation of noise control techniques that are based on minimization of local volume displacements, velocities, or accelerations...

...Yuan Shu-Qing,; Xu Qing-Yu,; Zhang Ling Experiments are performed to actively suppress vibration of a flexible four-bar linkage mechanism bonded with piezoelectric materials as sensor and actuator. The control system is built up with computer, A/D and D/A converter, low-pass filter, voltage...

...F. J. Shelley; W. W. Clark The purpose of this two-part work is to apply active mode localization techniques to distributed parameter systems where control actuator and sensor placement is a limiting factor. In this paper, Part 2 of the study, the SVD eigenvector shaping technique examined in Part...

...Franz J. Shelley; William W. Clark The purpose of this two-part work is to apply active mode localization to distributed parameter systems where the number of control sensors and actuators is a limiting factor. In this part, the theoretical development portion of the study, two approaches...
