ABSTRACT:
A dynamometer in combination with a torsional damping apparatus for damping torsional vibration between a prime mover and the dynamometer. The torsional damping apparatus includes a body plate rotatably coupled to a finger plate by a bearing, wherein the torsional damping apparatus interconnects the dynamometer and the prime mover. The finger plate includes a plurality of substantially radially outwardly protruding finger members engageable with a plurality of spring members at least partially disposed in corresponding recesses arranged about the rotation axis on the inner side of the body plate. An outer retainer ring removably coupled on the inner side of the body plate over the plurality of spring members for retaining the spring members in the corresponding recesses of the body plate. The finger members are engageable with the plurality of spring members to compress the plurality of spring members in response to relative rotational movement between the body plate and the finger plate about the rotation axis, wherein the spring members dampen torsional stress transmitted from the prime mover to the dynamometer.
