PROGNOSTIC TORSIONAL DAMPER DAMAGE DETERMINATION IN MACHINE SYSTEM

Prognostically warning of damper damage in a machine system (10) includes monitoring a machine (12) operating parameter linked with torsional loads on a crankshaft (20), and a temperature parameter. The prognostic warning strategy also includes populating an operating history of a machine system (10) 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.
