Abstract
A camshaft assembly may include a first shaft adapted to be rotationally driven, a first lobe member fixed for rotation with the first shaft, and a torsional damper fixed to the first shaft. The torsional damper may include a mass structure fixed to the first shaft and an elastic member disposed between and coupling the mass structure and the first shaft. The elastic member may have a spring constant providing a first sideband natural frequency and a second sideband natural frequency for the camshaft assembly.
