Reliability and structural integrity evaluation of rotating machinery: a case study on turbo-compressors with ANSYS workbench

Testbeds are essential structures in industrial labs for conducting machine testing, where the geometry and material properties play a critical role. These tests often use rotating equipment, such as turbines and turbo-compressors (TC). In order to achieve the best possible conditions, testbeds are created using ANSYS Workbench, which incorporates four mechanical procedures: modal, static, harmonic, and transient analyses. Simulations are used to reproduce attributes such as natural frequency, safety factor, and the highest and lowest levels of mechanical stress. This paper describes a quick way to check if the structure of a turbo-compressor is vibrated, by looking at things like its natural frequency, safety factor, and maximum mechanical stress. This study covers unknown factors and uncertainties by analyzing the operational states of the compressor. To achieve this, a reliability structure model and engineering methods like modal analysis for controlling vibrations, structural analysis to ensure the rotor rotates steadily, transient structural analysis to determine the appropriate startup conditions, and harmonic response analysis to determine how speeds change over time, are used to prevent to natural frequencies from interacting with operational frequencies, finally, transient analysis demonstrates initial shock and vibrations that result maximum stress.
