EN Vibration tests of marine gas turbine engines are performed as research of on-line and off-line types. On-line Systems generally monitored one or two vibration symptoms, which asses the limited and/or the critical values of parameters and they, potentially, can warn and/or shutdown engines. Off-line Systems are usually used for vibration analysis during non-steady state of work. The paper presents comparison of different methods of analysis of vibration symptoms measured under run-up and shut-down processes of marine gas turbine engines. Results of tests were recorded on gas turbine engine DR76 type of the COGAG type propulsion system. Main goal of the research was qualified on helpfulness and unambiguous result, from synchronous measurement, order tracking and auto tracking. All vibration symptoms were chosen from the methodology of the diagnosing gas turbine engines operated in the Polish Navy, called Base Diagnosing System. Second purpose of the paper was the estimation of the possibility of usage those analysis methods of gas turbine engines for on-line monitoring systems.
