ANALYSIS OF NONLINEAR VIBRATION CHARACTERISTICS OF DUAL-ROTOR SYSTEM UNDER BEARING MISALIGNMENT-RUB-COUPLING FAULT

Analysis of nonlinear vibration characteristics of dual-rotor system under bearing misalignment-rub-coupling fault

In order to reveal the vibration characteristics of fault rotor systems caused by the bearing misalignment, the expression of the rotor deflection displacement under the bearing misalignment was derived through the coordinate transformation here relation.On this basis, the dynamic model of the double disk rotor system with the coupled bearing misal

Double Redundancy Electro-Hydrostatic Actuator Fault Diagnosis Method Based on Progressive Fault Diagnosis Method

The electro-hydrostatic actuator (EHA) is the key component of most electric aircraft, and research on its fault diagnosis technology is of great significance to improve the safety and reliability of aircraft flight.However, traditional fault diagnosis methods only focus on partial failures and cannot completely diagnose the whole EHA system.In thi
