  • Prognostic torsional damper damage determination in machine system
    Patent number: 10890121
    Abstract: Prognostically warning of damper damage in a machine system includes monitoring a machine operating parameter linked with torsional loads on a crankshaft, and a temperature parameter. The prognostic warning strategy also includes populating an operating history of a machine system based on the monitored parameters, calculating a damper damage term based on the operating history, and triggering a damper damage warning where the damper damage term exceeds a threshold.

  • VISCOUS PENDULUM DAMPER
    Publication number: 20100175956
    Abstract: A damper that shears a fluid to dampen rotational force fluctuations and moves a plurality of masses within a fluid to dampen dynamic loading force fluctuations. The damper includes a case, a ring, a plurality of pockets, a mass, and a fluid. The case at least partially defines a case fluid cavity containing the fluid. The pockets are in the ring and the masses are in the pockets.
