An energy harvesting device based on acoustic levitation and an energy recovery method therefor

Abstract

The invention relates to an energy collection device based on acoustic wave suspension and an energy recovery method thereof, belonging to the field of ultra-precision manufacturing. The invention includes: a main body device, an air supply system, a sensing system, and an auxiliary support system. The gas purified and filtered by the air supply system is supplied into the air bearing of the main part to realize the suspension of the main part; the horizontal bracket limits the level of the suspension system. The displacement in the direction; the sensor in the detection system is bonded to the upper surface of the air bearing, and connected with the computer through the LMS detection system. The invention integrates the air bearing and the acoustic suspension, and collects and amplifies the high-frequency vibration of the air bearing during operation through the horn, so as to provide the high-frequency vibration energy required for the suspension for the acoustic suspension, and will not damage the air bearing The work, and recycle and reuse the vibration energy that is inevitably wasted when the air bearing is working, so as to achieve the purpose of energy recovery.

Description

technical field [0001] The invention relates to an energy collection device based on acoustic wave suspension and an energy recovery method thereof, belonging to the field of precision manufacturing. Background technique [0002] The essence of sound waves is also a kind of vibration. Acoustic levitation is a technology that uses high-frequency vibration to generate radiation pressure, and forms a squeezed air film between the radiation end surface and the suspended matter to achieve levitation. The characteristic of the acoustic suspension is that the suspended matter and the radiating end face rely on the air film to bear without contact, so there is no wear, and no air supply system and lubrication are required. In addition, the thickness of the air film suspended by the sound wave reaches the micron level, and the bearing precision is high. The levitation force and air film thickness of the acoustic levitation can be adjusted by adjusting the vibration frequency and am...
