“…The hybridization of these passive solutions is on the way in two main directions, apart from electromagnetic actuators, with the use of MR fluids or non-linear dampers. For the first alternative, recent works confirm its interest for an automotive application (Dong et al, 2020;Gao et al, 2019;Wang et al, 2022). This technology can also be hybridized with centrifugal pendulums to further improve damping capabilities (Abouobaia et al, 2020).…”

Recent hybrid control concepts, mixing active control with a fail-safe passive device, have drawn attractivity as they benefit from a theoretical hyperstability, ensuring very high stability margins. However, they have been experimentally tested until now only for the control of bending vibrations. The main purpose of this paper is to prove the performance of such systems also on torsional vibrations, with a specifically designed electromagnetic device, in order to contemplate the possibility to use them also for rotating machinery. As these control laws are model-free and require the adjustment of a few parameters related to the passive damper only, we demonstrate here their ease of integration for an application in rotating machines and we exhibit a direct experimental validation on an academic test bench. The latter which enables this experience despite the peculiarities of the rotation is therefore described, and the torsion reduction permitted by the hybrid control laws is assessed. A comparison between two of the newest hybrid control laws is also provided, proving the robustness and performance of these two hyperstable control laws. The main control parameters have been investigated and the performances are given through classical indicators but also in terms of energy consumption.

“…The current research on semi-active dampers focuses on smart materials, 12 for instance, magnetic fluid (MF), 13 magnetorheological fluid (MRF), 14 Since the smart materials can be adjusted according to external needs, they have a wide range of applications in damping, lubrication, etc. 15,16 Due to the large yield stress and damping force of MRF, it has been widely used in the field of damping, for instance, MRF dampers with double annular damping gap, 17 Integral MRF dampers, 18 MRF dampers for FUZZY-PID controller. 19 However, micron-scale MRF tend to aggregate and precipitate with poor stability.…”

For towering structures under complex time-varying excitation, the tuned magnetic fluid rolling-ball dampers (TMFRBD) cannot achieve self-tuning damping. In this paper, considering the operating characteristics of the TMFRBD, a damper self-tuning control algorithm, namely particle swarm optimization (PSO)-FUZZY-PID, is proposed for real-time adjustment of the intrinsic frequency of TMFRBD, which can greatly improve the damping effect, namely self-tuning magnetic fluid rolling-ball dampers (STMFRBD). Firstly, the equivalent dynamics model of the damping system is established, deriving the structural dynamic amplitude response as a function of the excitation frequency to structural frequency ratio. Different frequency tracking schemes of the damper are compared and analyzed. Then magnetic field simulations and magnetic fluid magnetic property measurements are performed for the dampers, respectively. Secondly, the self-tuning PSO-FUZZY-PID control algorithm is designed to improve the damping performance of STMFRBD under time-varying excitation by optimizing factors of the FUZZY-PID controller with PSO. To confirm the effectiveness of the damper self-tuning control algorithm, the frequency tracking of dampers with different control algorithms under time-varying excitation is compared. The results show that the damper’s frequency can be tuned quickly and accurately tracking excitation frequency by PSO-FUZZY-PID. Finally, the simulation and experimental results of STMFRBD and passive mass damper (PMD) under different loads are analyzed, and the structural amplitude response is analyzed using the Hilbert-Huang transform (HHT). In addition, the damping of STMFBD and TMFBD under different loads is compared. The results show that STMFRBD has better vibration-damping performance than PMD and TMFRBD.

“…Dual-rotor bearing systems, which are at the heart of aeroengines, have sophisticated structures, complex mechanical behaviors, multi-physics field coupling and multi-nonlinearity coupling [1,2]. Moreover, these systems generally work for a long time with a high rotational velocity, a large span between the fulcrum and a large thermal deformation [3]. If the whole or parts of these systems slightly malfunction, the consequences are most likely tragic.…”

Taking the dual rotor system in the aero-engine as the research object, the vibration behaviors of the dual rotor bearing system with fault-free, misalignment fault, rub impact fault and misalignment rub impact coupling fault are studied, respectively. Firstly, the three-dimensional model of the dual rotor bearing system is established, and then the first six modes and critical speeds of the dual rotor bearing system are obtained by the finite element method. Then, the dynamic equations of the dual rotor bearing system with fault-free, misalignment fault, rub-impact fault and misalignment rub-impact coupling fault are derived based on the Lagrange method. The Runge-Kutta method is used to solve the dynamic equation, and the nonlinear dynamic response of the system is obtained. The vibration behaviors of the dual rotor system with misalignment fault, rub-impact fault and misalignment rub impact coupling fault are analyzed and discussed through the time history, phase diagram, and frequency spectrum of the rotor. The vibration behaviors of the first six modes of the dual rotor system with fault-free, misalignment fault, rub-impact fault and misalignment rub-impact coupling fault are analyzed, respectively. The results can provide theoretical guidance for structural optimization design of the aero-engine rotor system and the prior decision information for misalignment and rub-impact coupling fault diagnosis.
