This paper presents a new kind of shock absorber, hydraulic electromagnetic energy-regenerative shock absorber (HESA), which can recover energy from vibration of vehicles. The road excitation frequency, load resistance and damping ratio are found to greatly affect the energy recovery of HESA. Based on a quarter-car model, the optimal load resistance and damping ratio for maximizing the energy-r...
In this study the use of an inerter is considered for active vibration control of a structure excited by white noise. The structure is modelled as a single degree of freedom system and the control system consists of a vibration absorber with a mass suspended on a spring, a damper and an inerter. The absorber is equipped with a reactive force transducer velocity of the structure under control me...
This paper presents a simulation study concerning the low-mid frequencies control of flexural vibration in a lightly damped thin plate, equipped with five time-varying shunted vibration absorbers. The panel is excited by a rain-on-the-roof broad frequency band stationary disturbance. The absorbers are composed of piezoelectric patches connected to time-varying RL shunt circuits. Continuous, swe...
An effective wide band active control law through one kind of the Dynamic Vibration Absorber (DVA) is proposed and studied in this paper. With the help of mechanical impedance method, active DVA control law is formulated based on the passive mechanical model. The electrical DVA can generate multi-mode active damping to the structure. The host structure is an aluminum plate and acceleration sign...
