摘要：
A propshaft assembly includes a shaft structure having a hollow cavity and an insert member being positioned within the hollow cavity and engaging the shaft structure. The shaft structure vibrates in response to receipt of an input of a predetermined frequency such that a shell mode anti-node is generated. The insert member is located at a position that approximately corresponds to the anti-node and has a compressive strength that is tailored to an anticipated displacement of the anti-node to thereby attenuate vibration of the shaft structure.
