Reducing vibrations generated in a gas turbine model MS9001E used in south Baghdad power plant station by improving the design of bearings with damper

الملخص EN

Gas turbines are engines an energy plant makes use of for generating the rotary motion to show power generators.

The gas turbine is largely a combustion engine for changing natural gas or different liquid fuels to rotational mechanical energy.

Often, the gas turbine generates excessive noise or vibrations.

In this work, the problem of vibrations occurrence in the gas turbine model MS9001E used in the south Baghdad power station is solved.

This is done by making a groove in the bearing pad to increase the oil flow, replacing the bearing type with a tilt-pad bearing type with damper.

The finite element method was used in the analysis process by ANSYS program.

The results showed a decrease in the values of vibration amplitude, total deformation, stress, and strain
