Product Introduction:Friction dampers consist of one central steel plate flanked by two outer steel plates, with the friction materials sandwiched in between.
Product features:When the central plate moves relative to the outer plates, the kinetic energy is converted into heat due to the friction. The energy dissipation abilities of these dampers are relatively consistent across various speeds and displacements. The hysteresis curves exhibit predominantly a rectangular shape.
Product Introduction
These friction dampers feature a straightforward structure, offering cost-effectiveness and requiring minimum maintenance.
