Process driving turbines have been used for a long time in high-temperature and high-pressure environments and are placed in poor environmental conditions, so the stability of the design to prevent deformation or damage is very important. The retainer, which is a core part of the turbine, rotates under steam pressure of high temperature and high pressure, so safety against deformation and damage due to vibration must be ensured. Therefore, safety verification after design is an essential process in turbine design. The purpose of this study is to verify the stability of the process retainer design by finite element analysis. There may be several methods for verifying the stability of a machine, but as machine parts become more complex and diversified, the finite element method is increasingly used. For stability verification, after verifying the deformation and damage of the part by static analysis, the possibility of fatigue failure was checked through the fatigue safety factor and fatigue life through fatigue analysis. In order to verify the safety of the rotating retainer, the possibility of occurrence of resonance according to the natural frequency was confirmed, and total deformation was confirmed through a harmonic response. Through this series of processes, it was verified that the designed retainer, the subject of this research, is safe.
