Abstract

The invention discloses a magnetorheological fat-based self-powered damping adjustment device, which comprises a damping system and an energy conversion and storage system, wherein the damping system comprises a magnetorheological fat working cylinder and a magnetorheological fat damping adjustor for adjusting the pressure difference of two working cavities of the magnetorheological fat working cylinder to form a damping force; and the magnetorheological fat damping adjustor is supplied with power by an electrical energy storage circuit of the energy conversion and storage system. The magnetorheological fat is adopted as a damping medium and has high stability in long time, and the energy conversion and storage system converts alternating pulse pressure fluctuation generated by structural vibration in the two cavities of the magnetorheological fat working cylinder into electrical energy to realize novel efficient vibration energy collection and storage, provide the electrical energy for the magnetorheological fat damping adjustor and ensure the energy supply of the whole magnetorheological controllable damping system without needing external energy input.

Description

technical field [0001] The invention relates to a structure vibration control device, in particular to a damping adjustment device in a semi-active control system that can achieve control effects without external energy supply. Background technique [0002] Structural vibration control is to reduce the seismic response of the structure and ensure the safety of the structure by installing various control devices in the structure. It mainly includes three categories: passive control, active control and semi-active control. [0003] Passive control is to install a passive damper on the structure to limit or damp the vibration of the structure. Its characteristic is that it does not need to input external energy. The characteristics of the damper are uncontrollable, and it can only exert good vibration on the vibration excitation under the design conditions. inhibition. Active control requires real-time measurement of structural vibration characteristics. Active control algori...
