Problems solved by technology

However, this kind of damper only uses shape memory alloy to achieve the purpose of energy consumption. Since the price of shape memory alloy is more expensive than that of ordinary alloy, the price of this type of damper is relatively high, which is not suitable for large-scale use.

Abstract

The invention discloses a multiple combination energy-dissipating damper, comprising an auto-adjustable frictional energy-dissipating device and a shape memory alloy energy-dissipating self-restoring device; the auto-adjustable frictional energy-dissipating device comprises a main plate, an upper auxiliary plate and a lower auxiliary plate, the main plate is connected to the upper auxiliary plate and the lower auxiliary plate through high-strength bolts, and friction sheets are penetrated by the high-strength bolts and clamped between the main plate and the upper auxiliary plate as well as between the main plate and the lower auxiliary plate; the shape memory alloy energy-dissipating self-restoring device comprises a rocking plate, a left slide rod, a right slide rod and shape memory alloy wires, the head of the rocking plate is hinged to the main plate, the upper and lower auxiliary plates are each provided with a left slide hole and a right slide hole, the left slide rod and the right slide rod are arranged in the left slide hole and the right slide hole respectively, and the ends of the left and right slide rods are wound with the shape memory alloy wires. The shape memory alloy energy-dissipation and frictional energy-dissipation are combined in the multiple combination energy-dissipating damper; the multiple combination energy-dissipating damper has good energy-dissipating shock reduction and restoring functions; a displacement amplifier is provided, so that the shape memory alloy wires are more value in use and the cost is low.

Description

technical field [0001] The invention relates to the fields of civil engineering and construction, in particular to a multiple composite energy dissipation damper. Background technique [0002] In civil engineering and construction, dampers are commonly used to dampen vibrations caused by earthquakes or high winds. However, durability and corrosion resistance are common problems in current dampers. After a period of use, the damper is prone to aging, or the deformation cannot be recovered, resulting in a decrease in the reliability of the damper. [0003] Shape memory alloy is a new type of functional material with both sensing and driving capabilities. It has the excellent quality of shape memory effect and superelasticity. Compared with other dampers, the passive energy dissipation shock absorber made of shape memory alloy has It has the advantages of good durability and corrosion resistance, long service life, large deformation and recovery. [0004] The Chinese patent w...
