Comprehensive Performance Testing And Analysis Of Fluid Bearing Tilting Pad Journal Bearings

Tilting pad bearings have friction due to low power consumption, more stable operation, with automatic regulation, is widely used in high-speed, heavy-duty work environment. The rapid development of science and technology in the industry today, large rotor system vibration and noise reduction has become the industry trends, so the traditional lack of tilting pad bearings dynamic properties make it difficult to meet the vibration and noise reduction now on industrial demand. This paper studies a fluid bearing tilting pad bearings, bearing the traditional tilting pad bearings improved mechanical fulcrum for flexible use of fluid to support Bush, to further improve the fluid tilting pad bearings overall performance, and will have a favorable impact on the operating conditions of the rotating shaft.First, tilting pad journal bearing fluid overall performance is analyzed theoretically. By finite difference method tilting pad bearings Reynolds equation, written computer program three watts tilting pad journal bearing oil film pressure distribution, using MATLAB software iteration Reynolds equation to calculate the oil film bearing capacity and bearing oil film thickness, draw a comprehensive performance space film pressure and film thickness distribution, sorting out the various performance parameters in order to estimate the value of the bearing fluid bearing tilting pad bearings. Then the fluid tilting pad bearings overall performance experimentally tested. By inverted bearing performance test station bearing static load test and dynamic load test, get the bearing capacity fluid bearing tilting pad bearings, temperature and axis trajectory static stiffness and damping properties and other dynamic performance data. By being mounted bearing performance bench comparative tests conducted damping bearings, get performance data damping fluid bearing tilting pad bearings.Finally, the fluid tilting pad bearings comprehensive performance test data post-processing work. By writing MATLAB data analysis software analysis and calculation finishing a lot of experimental data and has been integrated performance parameters fluid tilting pad journal bearings. Comparative test results and theoretical analysis results were mutually verified and comprehensive assessment of the fluid tilting pad bearings overall performance characteristics.
