Abstract
One embodiment includes a damped product including a first portion, a second portion, a first cavity formed in one of the first portion or the second portion, and a frictional damping insert at least partially received in the first cavity so that the first portion and the second portion completely enclose the frictional damping insert and so that vibration of the product is damped by the insert.
Claims41
A method comprising:
- providing a first portion of a part;
- providing a second portion of the part, and wherein at least one of the first portion or the second portion has at least a first cavity;
- providing a frictional damping insert constructed and arranged to provide frictional damping of the part;
- positioning the insert so that at least a portion of the insert is received in the first cavity;
- and
- joining the first portion and the second portion of the part to enclose the insert.
