Development of velocity and displacement sensor for vibration control

摘要

This study is concerned with the development of a new type of sensor for vibration control. This sensor belongs to the class of seismo-type. The main features of this sensor compactness, robust against shock and also to measure velocity and displacement simultaneously under the low frequency range. Until now, in order to measure the absolute displacement under low frequencies, the conven- tional sensor has to be made with its low natural frequency.
