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.
