Bending Vibration Characteristics of a Novel Piezoelectric Composite Trilaminar Vibrator [PDF]
Materials, 2021 In this work, the bending vibration characteristics of the 2-2 piezoelectric composite trilaminar vibrator are studied by the finite element simulation and experiment. The simulation results show that the trilaminar vibrator has lower resonant frequency and larger vibration displacement under the fixed boundary condition compared with that of the free ...

Vibrational characteristics of harp soundboards
The Journal of the Acoustical Society of America, 2008 Harps exist in different forms, from large factory-made concert harps to small hand-made folk harps. This variety presents both a challenge and an opportunity for acousticians. The musical quality of a harp depends on many factors, but key among these is the soundboard. This work sets out to define some general desirable qualities of a harp soundboard.

Characteristics and Applications of Vibration Galvanometers [PDF]
Transactions of the American Institute of Electrical Engineers, 1912 In the vibration galvanometer we have a type of synchronous motor which is distinctly different from all the ordinary types of dynamo electric machines. Further it does not have any of the characteristics of any of the ordinary galvanometers and except for the fact that it is used in the detection or measurement of small currents and voltages, it ...
