SYSTEM AND METHOD FOR MONITORING THE HEALTH OF A DAMPER FOR A RAIL VEHICLE

There is provided a method for detecting failure of a gas-hydraulic damper for a rail vehicle, comprising: - receiving a first input signal (S1) indicative of a stroke related parameter of the gas-hydraulic damper determined at a first time instance, - determining a first stroke value, based on the...

Beschreibung
Zusammenfassung:	There is provided a method for detecting failure of a gas-hydraulic damper for a rail vehicle, comprising: - receiving a first input signal (S1) indicative of a stroke related parameter of the gas-hydraulic damper determined at a first time instance, - determining a first stroke value, based on the first input signal (S1), - receiving, at least one second input signal (Si), wherein each subsequent signal (Si) is indicative of a respective stroke related parameter measured at a respective subsequent time instance, - determining a respective stroke value based on each of the second input signals (Si), - determining a stroke value over time based on the determined stroke values, and - determining that there is a failure of the gas-hydraulic damper if the stroke value over time, fulfils a first criterion. Also provided are a system, a gas-hydraulic damper and computer program product.
