Abstract

The invention discloses a novel self-resetting shearing type lead damper. The novel self-resetting shearing type lead damper comprises a left lug plate, an auxiliary cylinder, a first spring, a main cylinder, an outer barrel, a lead core, an end cover, a right lug plate, a second spring, a first baffle and a second baffle, wherein the right end of the main cylinder and the right lug plate are connected into a whole through a thread pair, the left end of the main cylinder is embedded into the auxiliary cylinder to form sliding fit, the left end of the auxiliary cylinder and the left lug plate are connected into a whole through a thread pair, the first spring is arranged on the inner sides of the main cylinder and the auxiliary cylinder, the left end of the first spring and the left lug plate are fixed into a whole, and the right end of the first spring and the right lug plate are fixed into a whole; the outer barrel is arranged outside the main cylinder, the inner side of the left end of the outer barrel is connected with the auxiliary cylinder into a whole through a thread pair, and the inner side of the right end of the outer barrel is connected with the end cover into a whole through a thread pair; the first baffle is vertically arranged on the outer barrel, the second baffle is vertically arranged on the main cylinder, and the second spring is arranged between the first baffle and the second baffle; the lead core is embedded into a gap ring groove formed between the main cylinder and the outer barrel, the main cylinder drives the lead core to slide relatively when sliding, and energy is consumed in a shearing mode.

Description

technical field [0001] The invention relates to the technical field of energy dissipation and shock absorption, in particular to a novel self-resetting shear type lead damper. Background technique [0002] With the acceleration of the urbanization process in our country, the scale of the city is expanding, and the urban building structure is more complicated. In the seismic design, not only the safety of people's lives must be considered, but also the economic loss caused by the damage to the building structure and equipment should be considered. Traditional structures The anti-seismic method is to passively resist the earthquake action by enhancing the anti-seismic performance of the structure itself. Due to the randomness of the earthquake, people cannot accurately estimate the intensity and characteristics of the future earthquake action. In performance-based seismic design, the "maximum deformation" of a building is an important index to measure the seismic performance a...
