ABSTRACT:
The present invention is a system and method for nondestructive vibrational testing of a specimen, such as a paper core tube. The system analyzes transverse vibrations of the simply supported specimen. The system measures the weight change at one end of the specimen and determines the frequency of vibration and the rate of energy loss. The testing is such that the specimen can be used after testing.
