Embodiment 1

[0031] In this embodiment, a damping structure is provided, such as figure 1 with figure 2 As shown, it includes: a shock absorber 1, the shock absorber 1 is formed with a closed hollow cavity 11, the hollow cavity 11 is provided with a magneto-rheological fluid, and one side of the hollow cavity 11 is provided with an excitation coil 2, and when the excitation coil 2 is energized , by controlling the current of the exciting coil and adjusting the magnetic field of the exciting coil, the natural frequency of the vibration damping body 1 is changed, thereby reducing the vibration response of the vibration damping structure.

[0032] The damping body 1 in this embodiment can be a damping body, that is, the inside of the damping body is a hollow cavity, which can be formed by buckling and welding two plates with grooves, and the hollow cavity 11 is provided with a magnetic flow The damping body can be used as the casing of the equipment or the cover of the transmission parts. ...

Embodiment 2

[0036] This embodiment provides a device, the device has a vibration source, the device includes the vibration-damping structure described in the first aspect, and the vibration source transmits the vibration to the vibration-damping body.

[0037] The equipment in this embodiment may be an outdoor unit of an air conditioner, or other equipment with a vibration source. When the device is an outdoor unit of an air conditioner, the vibration damping body serves as a housing or a vibration damping foot pad of the outdoor unit of an air conditioner. When the damping body is used as the shell of the air conditioner outdoor unit, the damping body is a sheet metal structure, which can be welded together by two pieces of sheet metal with grooves to form a sheet metal structure, and the two grooves are fastened to form a Hollow cavity 11. Such as image 3 As shown, the housing of the air conditioner outdoor unit is surrounded by a top cover 5, a front panel 9, a bottom panel 6, a rea...

Embodiment 3

[0039] This embodiment provides a method for controlling the equipment described in Embodiment 2 as an example. The equipment in Embodiment 2 is provided with a control system; the control method of this embodiment includes: when the compressor starts to run, the compressor generates The vibration is transmitted to the damping body through the pipeline. At this time, the vibration sensor can collect the vibration frequency of the sheet metal structure and feed it back to the control system. The control system analyzes the current vibration frequency and compares it with the preset vibration frequency. , if the current vibration frequency of the vibration damper is lower than the preset vibration frequency, the current state remains unchanged; if the current vibration frequency of the vibration damper is greater than or equal to the preset vibration frequency, the control system energizes the excitation coil to generate a magnetic field. Through this step, the vibration frequenc...

Abstract

The invention discloses a vibration reduction structure and device, a control method of the vibration reduction structure and device, a processor and a storage medium, belongs to the technical field of vibration, and aims to solve the problem that when vibration is generated during operation of existing equipment, a vibration reduction device cannot be adjusted according to the vibration frequency of the equipment, and the vibration reduction effect is limited. The vibration reduction structure comprises a vibration reduction body, a closed hollow cavity is formed in the vibration reduction body, magnetorheological fluid is arranged in the hollow cavity, a magnet exciting coil is arranged on one side of the hollow cavity, and when the magnet exciting coil is powered on, the magnetic field of the magnet exciting coil is adjusted by controlling the current of the magnet exciting coil, so that the magnetorheological fluid flows into the magnet exciting coil; and the inherent frequency of the vibration reduction body is changed, so that the vibration response of the vibration reduction structure is reduced. The inherent frequency of the vibration reduction body is changed by changing the current of the excitation coil, the current can be adjusted according to the amplitude of an actual equipment vibration source so as to change the inherent frequency of the vibration reduction body, the noise of equipment is reduced, and meanwhile resonance can be avoided.
