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.

Description

technical field [0001] The present disclosure relates to a method for manufacturing a damped propshaft assembly. Background technique [0002] This section provides background information related to the present disclosure which is not necessarily prior art. [0003] Consumers of modern autonomous vehicles are increasingly influenced by their satisfaction with the vehicle's acoustic quality in their purchasing decisions and their opinion of the vehicle's quality. In this regard, consumers increasingly expect the interior of a vehicle to be quiet and free from noise from the powertrain and drivetrain. Consequently, vehicle manufacturers and their suppliers are under constant pressure to reduce noise to meet increasingly stringent consumer expectations. [0004] Powertrain components and their integration into a vehicle typically play an important role in the sound quality of a vehicle, as they can provide a reinforcing function that stimulates specific driveline, suspension ...
