The vibration frequency characteristics of a rotor system are directly related to its moment of inertia. In this paper, a moment of inertia adjustment device is proposed to adjust the frequency characteristics of a rotor system and better reduce vibration by changing the moment of inertia. First, a mathematical model of the moment of inertia and the temperature field are established. A finite element simulation model of the electromagnetic field of the electromagnetic control unit in the device is established. The influence of current and air gap on the electromagnetic forces is discussed. Then, the validity of the finite element simulation for the electromagnetic control unit is verified using experimental results. In addition, the variations in the displacement and force of the moving mass and the moment of inertia of the device with speed are analyzed. The results show that the proposed moment of inertia adjustment device can be used to significantly adjust the moment of inertia, which provides a reference for better controlling vibrations in rotor systems. Finally, a finite element simulation model for an electromagnetic field analysis of the electromagnetic control unit in the device is established. The results show that the maximum temperature of the electromagnetic control device is 332 K in 60 min, which is in accordance with the requirements.

This study proposes a dual-coil magnetorheological torsional vibration damper (MRTVD) and verifies the effectiveness of semi-active damping control to suppress the shaft system’s torsional vibration via experimental research. Firstly, the mechanical model of the designed MRTVD and its coupling mechanical model with the rotating shaft system are established. Secondly, the torsional response of the shaft system is obtained via resonance experiments, and the influence of the current on the torsional characteristics of the magnetorheological torsional damper is analyzed. Finally, the MRTVD is controlled using the skyhook control approach. The experimental results demonstrate that when the main shaft passes through the critical speed range at various accelerations, the amplitude of the shaft’s torsional vibration decreases by more than 15%, and the amplitude of the shaft’s torsional angular acceleration decreases by more than 22%. These conclusions validate the inhibitory effect of MRTVD on the main shaft’s torsional vibrations under skyhook control.

In addressing the distinct influence mechanisms of torsional stiffness, torsional damping, and moment of inertia on the torsional vibration behavior of transmission systems, a human-simulated intelligent control strategy based on hybrid Taguchi genetic algorithm is proposed for the torsional vibration of magneto-rheological (MR) transmission system with variable stiffness, variable damping and variable inertia. Initially, the research conducts an in-depth analysis of the effects exerted by torsional stiffness, torsional damping, and moment of inertia on the transmission system dynamics. Subsequently, a comprehensive dynamics model for the MR transmission system with adaptable stiffness, damping, and inertia parameters is formulated, grounded on the conceptualization of an MR torsional vibration absorber. Drawing from the dynamic optimization outcomes facilitated by the hybrid Taguchi genetic algorithm, control parameters governing torsional stiffness, torsional damping, and moment of inertia are refined. This refinement process underpins the design of a human-simulated intelligent controller distinguished by its partitioned and multimodal characteristics. Notably, this controller framework is crafted to accommodate considerations across both temporal and spectral domains. Following the controller's design phase, rigorous simulation analyses are conducted to assess its efficacy. Results substantiate that the human-simulated intelligent control mechanism, underpinned by the hybrid Taguchi genetic algorithm, proficiently attenuates torsional vibrations across a broad spectrum of frequency bands. Furthermore, it is observed to markedly enhance the overall output characteristics of the MR transmission system.
