DESIGN AND ANALYTICAL INVESTIGATIONS OF CRACK PROPAGATION ON ROTOR SHAFT

The fast-moving rotary components of various machines (such as steam turbines, gas, pumps, generators, high-speed compressors, etc.) are widely used in various fields, such as aircraft, cars and power generation. The rotor column is one of the main parts of the various rotary machines. Due to manufacturing defects or periodic loading, there is often a fatigue force in the shaft. Stress is one of the main causes of catastrophic spin failure. Thermal machines such as steam turbines, thermal stress and thermal shock are also responsible for high voltage density, which is also a reason to start cracking and reproducing. In this project, constant analysis is determined to identify distortion, voltage, pressure on rotor force, and typical analysis of frequency distortion in different situations to determine vibrations of rotor and fracture analysis.
