Summary

Vibration is a common phenomenon in nature, which can bring many benefits to human beings, but also brings harm. Beneficial vibrations can be converted into other forms of usable energy, produce beautiful notes, transmit signals, etc., which will bring great benefits to the improvement of human living standards and the development of military technology. However, when the vibration exceeds a certain limit, it will cause damage to human health and facilities, making the instrument and equipment unable to work normally. For example, advanced aircraft such as artificial earth satellites, unmanned aerial vehicles, manned spacecraft, space probes, armed helicopters, strategic missiles, etc., have a serious hazard to the stability of the aircraft system due to the vibration and noise caused by the complex external environment. This makes the system unable to realize the effective positioning of the target during the flight, and the anti-jamming efficiency is poor. Converting these harmful vibrations into energy can not only eliminate harmful vibrations to protect equipment, but also capture energy to power microelectronic devices.

    CMES-Computer Modeling in Engineering & Sciences, Vol.135, No.3, pp. 2425-2448, 2023, DOI:10.32604/cmes.2023.023116
    (This article belongs to this Special Issue: Vibration Control and Utilization)
    Abstract This paper proposed method that combined transmission path analysis (TPA) and empirical mode decomposition (EMD) envelope analysis to solve the vibration problem of an industrial robot. Firstly, the deconvolution filter time-domain TPA method is proposed to trace the source along with the time variation. Secondly, the TPA method positioned the main source of robotic vibration under typically different working conditions. Thirdly, independent vibration testing of the Rotate Vector (RV) reducer is conducted under different loads and speeds, which are key components of an industrial robot. The method of EMD and Hilbert envelope was used to extract the fault feature of… More >

    CMES-Computer Modeling in Engineering & Sciences, Vol.135, No.1, pp. 395-416, 2023, DOI:10.32604/cmes.2022.021650
    (This article belongs to this Special Issue: Vibration Control and Utilization)
    Abstract An underconstrained cable-driven parallel robot (CDPR) suspension system was designed for a virtual flight testing (VFT) model. This mechanism includes two identical upper and lower kinematic chains, each of which comprises a cylindrical pair, rotating pair, and cable parallelogram. The model is pulled via two cables at the top and bottom and fixed by a yaw turntable, which can realize free coupling and decoupling with three rotational degrees of freedom of the model. First, the underconstrained CDPR suspension system of the VFT model was designed according to the mechanics theory, the degrees of freedom were verified, and the support platform… More >

    Numerical Simulation Study of Vibration Characteristics of Cantilever Traffic Signal Support Structure under Wind Environment

    Meng Zhang, Zhichao Zhou, Guifeng Zhao, Fangfang Wang
    CMES-Computer Modeling in Engineering & Sciences, Vol.134, No.1, pp. 673-698, 2023, DOI:10.32604/cmes.2022.021463
    (This article belongs to this Special Issue: Vibration Control and Utilization)
    Abstract Computational fluid dynamics (CFD) and the finite element method (FEM) are used to investigate the wind-driven dynamic response of cantilever traffic signal support structures as a whole. By building a finite element model with the same scale as the actual structure and performing modal analysis, a preliminary understanding of the dynamic properties of the structure is obtained. Based on the two-way fluid-structure coupling calculation method, the wind vibration response of the structure under different incoming flow conditions is calculated, and the vibration characteristics of the structure are analyzed through the displacement time course data of the structure in the cross-wind… More >

    Abstract The high-performance morphing aircraft has become a research focus all over the world. The morphing aircraft, unlike regular unmanned aerial vehicles (UAVs), has more complicated aerodynamic characteristics, making itmore difficultto conduct its design, model analysis, and experimentation.

    (This article belongs to this Special Issue: Vibration Control and Utilization)
    Abstract The static aeroelastic effect of aircraft ailerons with high aspect ratio at transonic velocity is investigated in this paper by the CFD/CSD fluid-structure coupling numerical simulation. The influences of wing static aeroelasticity and the ‘scissor opening’ gap width between aileron control surface and the main wing surface on aileron efficiency are mainly explored. The main purpose of this paper is to provide technical support for the wind tunnel experimental model of aileron static aeroelasticity. The results indicate that the flight dynamic pressure has a great influence on the static aeroelastic effect of ailerons, and the greater the dynamic pressure, the… More >
