Sumitomo frcition damper, fricting shearing cut with scissors damper, slide type slot hole bolt node damping device, T shape core plate frictional damping
Device, pseudo-viscous frictional damper, multi-stage friction damper and some friction composite energy dissipation devices.
If the power that frcition damper provides is excessive, it is necessary to improve normal pressure, therefore the parameter error calculated can be caused
It is larger, also energy consumption effect is be easy to cause to significantly reduce, and also be easy to cause the failure of device.Therefore it needs to frcition damper
Progress is further perfect, can mainly pass through and improve area of friction surface, the reliability of Lai Tigao damper.
