Paper Abstract

In order to replace complex and expensive equipment for measurements of damping, an intelligent instrument was developed using a cantilever beam with computer control and analysis. Both an acceleration transducer and an eddy transducer were installed in this instrument. This allowed one of them to be selected when measuring material damping properties using samples either in regular or irregular shapes. Damping properties of several materials, such as magnesium alloys and aluminum alloys, were measured using this instrument in order to validate its veracity and reliability. The data obtained were found to agree well with those obtained from other raditional equipment applying the turning and swing method, which requires strict control of the shape and size of the sample. The results show that this miniature material damping measurement instrument avoids the deficiency of traditional equipment, and therefore should be very useful for engineering damping measurements that occur in unattenuated forced vibrations.
