Evaluation and Comparison of Coupling Stiffness and Damping based on Frequency Characteristics

抄録

This study proposes an evaluation method for the coupling characteristics based on the measured frequency function. Stiffness and damping can be identified from the resonance frequency and maximum vibration amplitude at the resonance frequency, respectively. Characteristics of various types of coupling; leaf-spring type couplings and a resin type coupling are evaluated by the proposed method to compare the difference of the characteristics. As the results, it is confirmed that the proposed evaluation method can adequately evaluate the coupling stiffness and damping characteristics. In addition, the difference of the characteristics of different types and structures of coupling can be evaluated and compared by the proposed method.
