 Abstract:

Impulsive excitation is a non-destructive test to determine the elastic properties of materials. The transient-decaying signal can be measured using a contact or non-contact type of sensor. The aim of this study is to assess the optimal contact sensor position for an impulsive excitation test purpose. Rectangular bar of medium carbon steel S50C is considered as a specimen in the experimental test with various contact sensor positions. The vibration dynamic responses in the resonant frequency in flexure mode from various different contact sensor positions are statistically analyzed to measure the precision of each position and to determine the significance differences among the all the positions.
