Abstract
A method for forming a propshaft assembly. The method includes: providing a hollow shaft; tuning a mass and a stiffness of at least one liner to form an intermediate damper, the intermediate damper being configured to attenuate at least one of a bending moment vibration and a torsion mode vibration that occurs at a first predetermined frequency; tuning the intermediate damper to form a tuned damper, the tuned damper attenuating the at least one of the bending moment vibration and the torsion mode vibration at the first predetermined frequency and also attenuating shell mode vibration; and installing the tuned damper into the hollow shaft.
