The harmonious quality attenuator damping device of two-way ring type

Bi-directional ring type tuned mass damper(TMD) damping device, it relates to a damping device. The utility model discloses a respond the unable problem that realizes reducing knob insulator type electrical equipment earthquake in order to solve the unable knob insulator type electrical equipment that reduces of prior art at the equipment under the earthquake motion effect. The utility model discloses a strutting arrangement, quality device and rigidity device, said strutting arrangement is the open ring type cavity material of trilateral closed one side, and the uncovered face at strutting arrangement is installed to the quality device, in the closed cavity of rigidity device disposed on strutting arrangement and quality device enclose one-tenth. The utility model discloses reduce the earthquake motion of knob insulator type electrical equipment and make the peak response of time spent, reached the purpose that reduces knob insulator type electrical equipment earthquake.
