Abstract
In an aspect, a torsional vibration damper is provided, comprising a hub portion that mounts to a crankshaft, an outer ring that includes an inertial mass, a plurality of radial connectors that are elastically deformable and a plurality of spacers that extend circumferentially between the radial connectors and which are elastically deformable by the radial connectors during flexure thereof. The spacers are non-metallic and dissipate energy from deformation via conversion to heat. The plurality of radial connectors have a circumferential spring rate Kin bending in a circumferential direction about the axis, and have an axial spring rate Kin bending in an axial direction, wherein Kis at least 10 times as large as K. The plurality of spacers have a circumferential spring rate Kra in the circumferential direction, and an axial spring rate Krb in bending in the axial direction, wherein Kra is less than 1% of K
