Problems solved by technology

[0005] After adopting the above structure, the change of damping can be realized by using the oil pipe circuit and the pressure gauge, so as to realize the protection of the stroke, but the structure of this method is relatively complicated, the cost is high, and the power supply needs to be connected at all times, which cannot be measured due to earthquakes, strong winds, power supply damage and aging. Factors, controllers and sensors often fail, poor reliability

Abstract

The invention discloses a novel viscous damper with an adjustable damping coefficient. The viscous damper comprises a cylinder body, a piston and a piston rod; the two ends of the cylinder body are provided with guide sealing mechanisms, the two ends of the piston rod are matched with the guide sealing mechanisms at the two ends of the cylinder body respectively, and the piston is arranged in themiddle of the piston rod; the piston rod drives the piston to move in the cylinder body, and the piston divides the cylinder body into a first space and a second space; a damping channel making the first space connected with the second space is formed in the piston rod, and a plurality of openings are formed in damping channel and in the portions, on the two sides of the piston, of the surface ofthe piston rod respectively; the openings are closed or opened by sealing elements along with the displacement of the piston. The viscous damper has the advantages of being simple in structure, low inmanufacturing cost and capable of achieving damping multi-stage adjustment without being connected with a power source.

Description

technical field [0001] The invention relates to a damper, in particular to a novel viscous damper with adjustable damping coefficient. Background technique [0002] Viscous damper is a speed-dependent damper, which was first used in machinery, military industry, aviation and other fields to control the vibration and shock of equipment. With the continuous advancement of technology, viscous dampers are gradually being extended to civil projects such as building structures and bridges to dissipate destructive energy caused by earthquakes and strong winds. The viscous damper mainly includes several technical indicators such as damping coefficient, damping index, and maximum output. The damping coefficient of conventional viscous dampers is a fixed value, which cannot meet the needs of different damping forces at different stages in actual use. [0003] Some existing products can realize the variable demand of the damping coefficient of the viscous damper, but the method of ch...
