The dual‐rotor structure was usually adopted in aeroengine for the sake of higher efficiency, where high‐pressure (HP) rotor and low‐pressure (LP) are coupled together through an intershaft bearing. For convenience manufacturing maintenance, bolt connections widely high‐power rotors to fasten multiple parts that manufactured separately. mechanical properties significantly affect dynamics, which need be precisely controlled design. Vibration transmission bearings leads complex dynamic behaviors connection system, more difficult control behavior connection. This study established motion equations a system with HP using finite element method deal effect mechanism vibration from LP on nonlinear responses Newmark solve equations, complicated influenced by different offset positions unbalanced force disk analyzed cascade spectrums, frequency–amplitude diagrams, time‐domain waveforms, shaft obits, bending stiffness diagram results show affects rotor’s response Finally, numerical simulation verified based test rig. investigation is helpful modeling can used predict characteristics during design process.

The turbine disk is the core component of an aero-engine whose position and unbalanced force seriously affect vibration stability rotor system. Ignoring influence offset may result in discrepancies between real-world scenarios numerical simulation results. present work aims to explore nonlinear dynamic characteristics systems under coupling bolted joint effect, as well its on system behavior bending stiffness also investigated. governing equations a rotor-bearing with were established based finite element method derived dimensionless expression first. Then, Newmark was employed for solution motion equations, then bifurcation analysis evolution studied. Next, by comparing frequency-amplitude diagrams, time history, shaft obits, diagrams joint, effect revealed. Finally, experimental study carried out verify using test rig disk. can provide theoretical guidance structure design aero-engine.
