“…The Lorentz force electromagnetic actuator yields a linear output force and a stable eddy current damping. 7,8 Applications of electromagnetic actuators 9–13 and magnetic damping 14–18 in vibration absorbers have been investigated extensively. If magnetic damping force and Lorentz force are realised in the same magnetic circuit, the structural dimensions of the EHVA can be further reduced.…”

This paper presents a novel type of electromagnetic hybrid vibration absorber (EHVA) with a double-ring series permanent magnetic circuit applied to improve the two-stage vibration isolation system of marine power machinery. The EHVA comprises a mover with several groups of coils having a series connection, as well as a stator with internal permanent magnets and external permanent magnets, which form a novel magnetic circuit structure based on an improved Halbach array. In this magnet circuit, two adjacent groups of magnetic induction lines overlap at the coil position, thereby strengthening the magnetic field intensity. When the mover moves axially, the coil cuts the magnetic induction line to produce Lorentz force and magnetic damping force. First, the dynamic parameters of the EHVA were calculated based on multi-rigid-body dynamic theory and fixed-point theory. Second, the mechanical and electromagnetic structures of the EHVA were designed. Finally, a test stand was constructed, the system control channel was identified, and the simulation as well as experiment for vibration control using an [Formula: see text] controller were performed. Results indicated that the hybrid vibration reduction system under control reduced the acceleration amplitude by 12.3 dB at 30.6 Hz and achieved better vibration absorption effects between 27 and 33 Hz compared with the uncontrolled system.

<div class="section abstract"><div class="htmlview paragraph">Hybrid electric vehicles (HEVs) with multiple vibration excitation sources have complex torsional vibration problems of the drivetrain. When the drivetrain system resonates, it will lead to an increase in vehicle vibration and noise. The parameters of the passive damping mechanisms cannot be adjusted in real time according to the torsional vibration level of the vehicle, and it is difficult to meet the damping requirements of each vibration frequency band. Active torsional vibration control systems need high cost and energy consumption, strict maintenance, and complex control technology in practical applications. A novel electronically controlled damper (ECD) is proposed in this paper and is applied to a parallel hybrid power system. The structure of the ECD is introduced, the dynamic model of the ECD is established, and the relationship curve is obtained between the electromagnetic damping torque, excitation current, and speed using finite element analysis (FEA). The dynamic differential equation of the hybrid power system is derived, and on this basis, the topology structure and damping range of the ECD are determined according to the sensitivity simulation results under different working conditions. The co-simulation analysis of AMESim and MATLAB/Simulink is carried out. The simulation results of different ECD systems under the acceleration condition show that the ECD with fuzzy control can significantly reduce the resonance amplitude of the HEV drivetrain, and the damping rate of the critical area between the resonance and the non-resonance can be accurately controlled to achieve the best damping effect. At the same time, the vibration suppression effect in the non-resonant area is always stable.</div></div>
