Inerter Damper

Inerter Damper

Product Introduction

The Inerter Damper is an energy-dissipating device that amplifies the damping effect by virtue of the inerter effect. Integrating inerter elements (featuring a negative mass effect and capable of amplifying relative structural motion) with damping elements, it enhances the damping force through the inerter effect to dissipate vibration energy with high efficiency.

Its core principle is based on the inerter theory: the inertial force of the inerter element is proportional to acceleration, and the element can amplify the relative displacement of the structure, thereby enabling the damping element to generate a greater damping force. Through this displacement amplification - damping enhancement mechanism, it dissipates vibration energy more efficiently and reduces the acceleration and displacement responses of the structure.

 

The relationship between its damping force F and velocity V is expressed as follows:

F=cVα+meV

F: Rated Damping Force (kN)

c: Damping Coefficient (kN/(m/s) α)

α: Velocity Exponent

V: Maximum Response Velocity (m/s)

me: Inertance Coefficient

a: Acceleration (m/s²)
