Vibration Control News Today

This article discusses the reasons why vibration control is necessary for active isolation systems.

The inerter was introduced as a mechanical counterpart to the electrical capacitor, completing the force-current analogy. This is a one-port, two-terminal device in which the equal and opposite forces exerted at its terminals are proportional to the relative acceleration between them. Within this relationship, the “inertance” is the coefficient of proportionality and carries the unit of mass. This implies that the inerter can exert an inertial force at its terminals, effectively representing...

This article proposes an electromagnetic damper (EMD) based on a ball screw mechanical structure actuator. To prove the damping effect of the new damper proposed in this paper. In this paper, the EMD suspension is validated on a quarter vehicle suspension. A mathematical model of quarter vehicle suspension is developed and a sliding mode variable structure controller is designed. This sliding mode controller enables vibration control of the suspension and improves ride comfort. To make the EMD t...

As the operation speed of high-speed train increases, trains with fixed suspension stiffness will encounter dramatical vibrations, especially when its lateral resonance occurs. This greatly affects the ride comfort and safety of the trains. Based on this motivation, a novel stiffness variable suspension system using magnetorheological elastomer (MRE) isolator with negative stiffness is proposed. The controllable stiffness can make the train avoid lateral resonance while the negative stiffness ch...
