Abstract

The invention provides a top-mounted multi-tuned mass damper shock absorber, which belongs to the technical field of shock absorbers, and solves the problem that the existing tuned mass damper technology cannot be used for long-period ceramic column type electrical equipment shock absorbers. The damping device includes a support device, a mass device and a stiffness device; the support device includes a vertical support group and N layers of horizontal supports; the quality device includes N pieces of mass blocks, wherein N is a positive integer; the mass blocks pass through the stiffness device Fixed installation on the supporting device. The N layers of horizontal supports correspond to the N mass blocks one by one, and the mass blocks are placed at the center of the upper surface of the horizontal support. The damping device is especially suitable for long-period electrical equipment, has low cost, little change to the equipment, and basically does not age.

Description

technical field [0001] The invention relates to a top-mounted multi-tuned mass damper shock absorber, which belongs to the technical field of shock absorbers. Background technique [0002] Earthquake disasters are sudden and devastating, which seriously threaten the safety of human life and property. Porcelain column electrical equipment is widely used in power systems, and with the development of the power industry, the level of power transmission and transformation equipment is getting higher and higher. The softer and softer the top, the greater the quality of the top, and the higher the requirements for its shock resistance. Porcelain column electrical equipment has been severely damaged in previous strong earthquakes at home and abroad. It is very important to ensure the normal operation of porcelain column electrical equipment under the action of earthquakes to ensure the safe operation of power systems. [0003] The main forms of damage to porcelain post type electr...
