Abstract

A piezoelectric-electromagnetic combined energy gathering vibration damping device is arranged below a floor or a decking, and aims to gather the kinetic energy in the floor or decking and convert same into electric power for storage; the electric power can be released so as to form a damping effect, thus alleviating the floor or decking vibrations; the piezoelectric-electromagnetic combined energy gathering vibration damping device mainly comprises an inductance coil, a permanent magnet, a lithium ion battery, a particle damping container, a multi-grading electromagnetic particle damping, a piezoelectric ceramics, a loading plate, anchoring bolts, an insulation pad, and an electric quantity identification and control induction member; anchoring bolts are reserved on the loading plate and the piezoelectric ceramics; each member is placed in the loading plate according to required positions; the whole device is fixed below the floor or decking through the anchoring bolts. The piezoelectric-electromagnetic combined energy gathering vibration damping device can gather and utilize the energy of vibrations in the environment, and can effectively alleviate the floor or decking vibrations.

Description

technical field [0001] The invention relates to a piezoelectric-electromagnetic composite energy-collecting and vibration-damping device, whose function is to collect, utilize and dissipate the vibration energy in a civil engineering plate structure to achieve the purpose of reducing the vibration amplitude of related components and structures, and belongs to new energy and structural damping. Background technique [0002] At present, with the increasing shortage of non-renewable resources in our country, seeking green renewable resources is an important challenge we face. There are a variety of renewable resources available in daily life, such as the vibration of floors or bridge decks caused by people or vehicles is a good kinetic energy resource, but these resources often cause inconvenience to engineering structures and users or are simply ignored. Therefore, in order to make better use of these unfavorable or negligible energy sources, the present invention proposes a ...
