[0066] The second embodiment differs from the first embodiment in that (refer to Image 6 ), there is a gap between the primary spring 14 and the built-in upper oil storage tank cylinder 16, and the multi-objective self-adaptive high-efficiency energy-consuming self-resetting anti-buckling support is divided into three different working stages according to the external excitation and deformation of the structure , and can be automatically adjusted according to the change of external excitation, so that the performance of multi-objective self-adaptive high-efficiency energy-consuming self-resetting anti-buckling support adapts to the current external excitation conditions. In the first stage, when the structure is subjected to environmental vibration (wind vibration, machine vibration, subway vibration, etc.), the multi-objective adaptive high-efficiency energy-consuming self-resetting anti-buckling support deforms very little, and does not need to provide self-resetting force f...

Abstract

The invention discloses a self-adaptive buckling-preventing support which comprises a sealing cylinder cavity. The top face of the sealing cylinder cavity is open. An upper sealing end cylinder is installed on the top face. A hole matched with a piston rod in radial size is formed in the center of the upper sealing end cylinder. The piston rod penetrates through the center hole of the upper sealing end cylinder and is partially installed in the sealing cylinder cavity. An energy consumption partition plate is installed on the piston rod. The energy consumption partition plate is transversely arranged on the piston rod in a sleeving manner, and moves in the sealing cylinder cavity along with moving of the piston rod. The sealing cylinder cavity is filled with damping liquid. Springs are further installed in the sealing cylinder cavity. The self-adaptive buckling-preventing support has the beneficial effects that the energy consumption partition plate can move along with the piston, an upper oil storing box cylinder, a lower oil storing box limiting cylinder and the energy consumption partition plate arranged internally have shearing and extruding effects on the damping liquid, the first-level spring and the second-level spring deform in an extruding manner to generate restoring force, after external force disappears, the piston rod is driven to carry out self restoring, and selfperformance can be adjusted automatically according to the change of the affected external excitation effect.

Description

Technical field: [0001] The invention relates to a shock absorbing device, which belongs to the technical field of shock resistance and shock absorption, in particular to a multi-objective adaptive high-efficiency energy-consuming self-resetting anti-buckling support. Background technique: [0002] Structural passive damping control technology is the earliest damping control method in the field of civil engineering, and has achieved fruitful results in both theoretical research and practical engineering applications. Structural passive shock absorption control technology is to install shock absorbing and energy-dissipating devices in certain parts of the structure, and reduce the dynamic response of building structures under earthquake action through the energy-dissipating capacity of the shock-absorbing and energy-dissipating devices. Structural passive damping control technology is cheap, simple in structure, easy to maintain and does not require external energy. Due to it...
