Problems solved by technology

[0005] However, the vibration suppression of the current feed system is generally based on the principle of mechanical friction, and the service life, stability, reliability and speed application range are relatively limited
The eddy current damper has simple structure, long life, high reliability, good stability, and wide application range of speed due to the non-contact and wear-free relative motion of moving parts and static parts in its structure. There is a greater possibility

Abstract

The invention provides an active eddy-current damping device. The active eddy-current damping device comprises a coil, a coil frame, a supporting body, a first conductor, a second conductor, a third conductor and a fourth conductor, wherein the first conductor, the second conductor, the third conductor and the fourth conductor are sequentially arranged from bottom to top. The second conductor and the third conductor are located on the lower surface and the upper surface of the supporting body respectively. The first conductor and the second conductor are supported by a first supporting frame to form first space. The third conductor and the fourth conductor are supported by a second supporting frame to form second space. A guide rail is arranged on the side face of the supporting body. The coil frame is arranged on the supporting body in a sleeving manner and connected with a sliding block. In the work state, alternating current is input in the coil to generate a magnetic field, the sliding block is driven by external force to move along the guide rail, the coil is driven to do no friction motion in the first space and the second space, the eddy current effect is generated, and damp output is achieved. The active eddy-current damping device can be used for the feeding system, restraining on vibration of the feeding system in the motion process is achieved, and motion precision and stability are improved.

Description

technical field [0001] The invention relates to the field of vibration control of a feeding system, in particular to an active eddy current damping device and a feeding system including the active eddy current damping device. Background technique [0002] Vibration is one of the important factors affecting the stability and precision of the high-speed motion process of the feed system. Dampers are an effective means of dampening vibrations. At present, dampers are widely used in static structures such as building structures and equipment beds, such as spring-mass dampers, piezoelectric crystal dampers, and magnetorheological dampers. However, due to limitations in structural performance and the like, it is difficult to apply the above-mentioned damper to moving parts. [0003] The eddy current effect means that when a conductor or semiconductor (hereinafter referred to as conductor) material is in a changing magnetic field or moves relative to a non-uniform magnetic field,...
