Performance Enhancement the Gas Turbines of Power Plants by using Tilt Bearings Development

Abstract

The gas turbine in Power Plants is an internal combustion engine that transforms liquid fuels into mechanical energy. The gas turbine frequently produces exaggerated vibrations or noise. This work aims to replace the type of bearing with a tilt-bearing kind with a mechanical damper and numerically replicate the process by creating a depression in the bearing pad to improve the oil's flow and reduce the generated vibration. The ANSYS application employed the finite element approach during the analysis phase. The analytical simulation to execute a dynamic analysis system for gas turbines proposed two cases before and after the development, simulating and comparing the outcomes of the cases. Following the adjustments, the system's deformation value dropped to 46.17%, its stress value dropped to 39.66%, and its strain value dropped to 61.47%. The harmonic analysis revealed that the deformation value fell to 38.18%.
