Vibration Characteristic Analysis of a Coupling System for Compound Biaxial and Inter-Shaft Bearings

<div>Amplitude-frequency curves of different stiffnesses of the inter-shaft bearing. Green: The coefficient of stiffness is 0.8. Blue: The coefficient of stiffness is 1. Pink: The coefficient of stiffness is 1.2 (Corresponding excitation resonance peak, inner shaft: BI<sub>K1</sub>, BI<sub>K2</sub>, BI<sub>K3</sub>, outer shaft: BO<sub>K1</sub>, BO<sub>K2</sub>, BO<sub>K3</sub>). (a) Inner shaft. (b) Outer shaft.</div>
