Development of autonomous downhole vibration measuring equipment
Известия высших учебных заведений: Геология и разведка, 2023 Background. Drilling vibrations may cause damage to the bit and early failure of downhole instruments. The main approach to solving this problem consists in measuring downhole vibrations while drilling by adding sensors near the bit in to the bottom hole

Longitudinal vibrations in piano strings [PDF]
The Journal of the Acoustical Society of America, 1987 The percussive excitation of a piano string by a hammer is expected to produce longitudinal string vibration components in addition to the desired transverse ones [e.g., Yanagisawa et al., J. Acoust. Soc. Jpn. 33, 412–416 (1977)]. However, so far little quantitative information exists in current acoustics literature on the contribution of such ...
