In the study presented in this paper, finite element analysis was used to optimize the design of a stator coupling in order to increase its natural frequency. Through design iterations and analysis, it was discovered that by increasing the center hole diameter of the coupling as well as introducing stiffening ribs at the flexible part of the structure, natural frequency will increase from its original design of 714Hz to an optimized design of 1611Hz.
