Problems solved by technology

Due to the inherent physical properties of materials and structures, existing passive shock absorbers are not ideal for low-frequency vibrations of tens of Hz
Especially because it is difficult to reduce their resonance frequency, there is basically no shock absorption effect for vibration interference below 20Hz

Embodiment 1

[0024] Embodiment 1: Magnetic shock absorption method

[0025] Vibration reduction is achieved by the repulsive force between the magnetic poles of the same sex and the air gap formed between the magnetic poles of the same sex to produce a damping effect.

Embodiment 2

[0026] Example 2: Magnetic shock absorber

[0027] Referring to Fig. 1, an upper magnet 1 and a lower magnet 2 are set opposite to each other. Between the upper magnet 1 and the lower magnet 2, an air gap 3 that changes with load or vibration is formed by the repulsive force between the magnets.

[0028] As shown in Figure 1, in the specific implementation, a cylindrical casing 4 is provided, and the cylindrical casing 4 is divided into two parts that can move relative to the upper and lower parts in the longitudinal direction. In the shape housing 4, the lower magnet 2 is fixedly arranged on the bottom plate 6, and the upper magnet 1 is suspended and fixed under the top cover 5. The overall shape is flat cylindrical. This structure is easy to install and can keep the upper magnet 1 The horizontal stability between the lower magnet 2 and the closure of the magnetic circuit at the same time prevent magnetic flux leakage interference. The upper magnet 1 and the lower magnet 2 us...

Abstract

The magnetic damping method and the dashpot are to form the air space to generate the damping effect by the repellant formed between the magnetic poles. The dashpot is set with the up magnet and the down magnet according to the same polar between which the air space with the thickness changed by the load or vibration is formed from the repellant. The dashpot has the simple structure, low cost and not only decreases the vibration disturbance of 20Hz but below 20Hz.

Description

technical field [0001] The present invention relates to a vibration reduction method and a vibration absorber, more specifically to a vibration reduction method and a vibration absorber for reducing the interference of external vibrations on precision instruments and equipment, such as electron microscopes and optical precision measurement. At the same time, it can also reduce the vibration generated by equipment such as fans and pumps, which interferes with other nearby equipment. Background technique [0002] In various industrial technology applications and precision measurement, in order to avoid the influence and interference of vibration, it is necessary to use various technical means, specifically the use of shock absorbers of various principles. [0003] Shock absorbers can be divided into two categories: active and passive according to their working principles. The active type is that the detector detects the direction and amplitude ...
