Embodiment Construction

[0027] Referring to the accompanying drawings, a reluctance type electromagnetic active vibration absorber includes: a housing composed of a lower mounting plate 1 of the vibration absorber, a cover 2 of the vibration absorber and an upper mounting plate 3 of the vibration absorber, and a mover assembly located inside the housing and stator assembly;

[0028] The mover assembly includes: two mover silicon steel sheets 12 with permanent magnets 11 embedded in the central groove of the end face; the two mover silicon steel sheets 12 are placed parallel to each other on the lower mounting plate 1 of the vibration absorber, and are installed with the lower vibration absorber. The plate 1 is vertical, and the end embedded with the permanent magnet 11 is opposite to each other. The two sides of each mover silicon steel sheet 12 respectively pass through the mover fixing screw 10 and the left fixed plate 6 of the mover silicon steel sheet, and the right fixed plate of the mover silico...

Abstract

The invention belongs to the technical field of vibration noise control and particularly relates to an active vibration absorber. The magnetic resistance type electromagnetic active vibration absorber comprises a vibration absorber lower installation plate, a vibration absorber cover, a vibration absorber upper installation plate, a rotor assembly and a stator assembly. Four rolling guide rail pairs are installed between the rotor assembly and the stator assembly. The rotor assembly is connected with the vibration absorber lower installation plate and the vibration absorber upper installation plate through springs. The rotor assembly can freely vibrate through the rolling guide rail pairs. The magnetic resistance type electromagnetic active vibration absorber can be installed and used in combination with various types of passive vibration absorbers and can be arranged on a controlled object or a base at will, after a coil is electrified with alternating current, electromagnetic force is generated between the rotor assembly and the stator assembly, the stator coil generates Lorentz force, the resultant force of the electromagnetic force and the Lorentz force drives a vibration absorber rotor to move, the vibration absorption force generated by the vibration absorber rotor is used for offsetting the vibration of the controlled object, and the purpose of controlling vibration is achieved.

Description

technical field [0001] The invention belongs to the technical field of vibration and noise control, in particular to an active vibration absorber. Background technique [0002] Vibration is a common phenomenon in production and life. With the continuous increase of operating speed, the vibration problem of mechanical equipment has attracted more and more attention. Vibration not only easily causes structural fatigue damage and affects the life of equipment, but also reduces the measurement accuracy of instruments and meters, resulting in the failure of electrical components and automatic control systems. At the same time, vibration inevitably generates noise, affecting the normal work of operators and even endangering health. And with the development of science and technology, some vibrations with very low natural frequency and wide frequency domain appear. For this type of vibration, passive vibration damping is powerless. In order to solve these problems, designers have...
