Problems solved by technology

At present, the three are designed and used independently. When performing active control of structural vibration, the three need to be connected by wires. It is complicated to use and it is easy to bring interference signals from the connecting wires. Many controlled objects are basically designed. There is no space to install the controller, and the actuators do not consider the impact of heat generated during long-term work on performance, and there are problems in practical engineering applications

Abstract

The invention aims at providing an integrated type inertia electromagnetic actuator. The integrated type inertia electromagnetic actuator comprises an outer permeability barrel, an upper end cover, a lower end cover, a first permanent magnet and a second permanent magnet. An upper magnetizer is installed above the first permanent magnet, a middle magnetizer is installed between the first permanent magnet and the second permanent magnet, a lower magnetizer is installed below the second permanent magnet, the upper magnetizer, the first permanent magnet, the middle magnetizer, the second permanent magnet and the lower magnetizer are connected into a whole to form a vibrator through a connecting bolt, the upper end and the lower end of the vibrator are provided with an upper leaf spring and a lower leaf spring respectively, the upper end cover is installed at the upper end of the outer permeability barrel, the upper leaf spring is fixed between the upper end cover and the outer permeability barrel, the lower end cover is installed at the lower end of the outer permeability barrel, the lower leaf spring is fixed between the lower end cover and the outer permeability barrel, and the inner wall of the outer permeability barrel is wound by an upper coil, a middle coil and a lower coil from top to bottom in sequence. The integrated type inertia electromagnetic actuator can be installed and used as long as being powered on, and installing and debugging time is shortened in the controlling process.

Description

technical field [0001] The invention relates to a vibration damping device, in particular to an active vibration damping device. Background technique [0002] With the continuous development of science and technology, the vibration requirements of the environment and equipment are getting higher and higher, and passive vibration isolation can no longer fully meet people's needs. Considering the active control of structural vibration through active components has attracted more and more attention. [0003] The actuator is an important link in the active control system of structural vibration. Its function is to apply control force to the control object according to the determined control law to change the vibration response of the system. Electromagnetic actuators have the advantages of wide operating frequency range, sensitive response, small driving current, large operating force, small volume and weight, and high reliability, and are currently widely used. [0004] Sensor...
