Vibration phenomena involve a wide range of engineering systems and structures such as buildings, vehicles, aircrafts, bridges, and electronic components. Due to the undesired effects of the vibration induced motions, the vibration control is a theme on which many researchers are focusing their attention in the recent years. The main scope of the vibration control is the suppression or, at least, the attenuation of the undesirable vibrations by means of passive, semiactive, or active devices. Hard nonlinearities can be found in vibrating systems because of inherent system nonlinear properties and/or the presence of dampers, stiffness elements, and actuators which are often characterized by hysteresis, dead zone, and so forth. This special issue intends to provide an up-to-date overview of recent advances in the vibration control of systems characterized by hard nonlinearities.

In the paper “Modelling of Hysteresis in Vibration Control Systems by means of the Bouc-Wen Model” by C.-M. Chang et al., applications of the Bouc-Wen model in vibration control devices are reviewed. The paper “Novel Distributed PZT Active Vibration Control Based on Characteristic Model for the Space Frame Structure” by H. Zhong et al. presents a novel distributed PZT control strategy based on characteristic model for space frame structure. The paper “Recent Advances in Bidirectional Modeling and Structural Control” by S. Paul et al. gives an overview of building structure modeling and control under bidirectional seismic waves. In the paper “Optimal Trajectory Planning and Linear Velocity Feedback Control of a Flexible Piezoelectric Manipulator for Vibration Suppression” by J. Lou et al., an optimal trajectory planning approach is proposed and applied to a flexible piezoelectric manipulator system. The paper “Nonlinear Seismic Behavior of Different Boundary Conditions of Transmission Line Systems under Earthquake Loading” by L. Tian and X. Gai investigates nonlinear seismic behaviors of different boundary conditions of transmission line system under earthquake loading. The paper “A Water Hammer Protection Method for Mine Drainage System Based on Velocity Adjustment of Hydraulic Control Valve” by Y. Kou et al. proposes a water hammer protection method based on velocity adjustment of hydraulic control valve to deal with the problem of valve-closing water hammer in mine drainage system. In the paper “Novel Hyperbolic Homoclinic Solutions of the Helmholtz-Duffing Oscillators” by Y.-Y. Chen, a new homoclinic solution of the Helmholtz-Duffing oscillator is presented. The paper “Modeling and Simulation of Flexible Transmission Mechanism with Multiclearance Joints for Ultrahigh Voltage Circuit Breakers” by F. Meng et al. proposes a planar rigid-flexible coupling dynamic model of high-speed multilink transmission mechanisms with clearance for ultrahigh voltage circuit breaker. In the paper “Experimental and Theoretical Study on Influence of Different Charging Structures on Blasting Vibration Energy” by W. Gu et al., a study is designed to deduce the law of different charging structures’ influence on blasting vibration energy of far region of blasting and provide reference for controlling side effects of blasting vibration and designing parameters of charging structure. The paper “Nonlinear Dynamics Analysis of the Semiactive Suspension System with Magneto-Rheological Damper” by H. Zhang et al. examines dynamical behavior of a nonlinear oscillator which models a quarter car forced by the road profile. The magneto-rheological (MR) suspension system has been established, by employing the modified Bouc-Wen force-velocity model of magneto-rheological damper.
