Energy collection device based on acoustic wave suspension and energy recovery method thereof

Abstract

The invention relates to an energy collection device based on acoustic wave suspension and an energy recovery method thereof, and belongs to the field of ultra-precision manufacturing. The energy collection device comprises a main body device, a gas supplying system, a sensing system and an auxiliary supporting system, wherein purified and filtered gas by the gas supplying system is fed into a gasflotation bearing of the main body part to realize suspension of the main body part; a horizontal support limits the displacement of the horizontal direction of a suspending system; and a sensor in adetecting system adheres to the upper surface of the gas flotation bearing and is connected with a computer through an LMS detecting system. According to the energy collection device, gas flotation support and sound wave suspension are integrated into a whole, the high-frequency vibration when the air flotation bearing works is collected and enlarged by an amplitude-changing rod to provide high-frequency vibration energy required during suspension for the sound wave suspension, the work of the air flotation bearing cannot be damaged, and vibration energy which is inevitably wasted when the air flotation bearing works is recovered and reused, so that the purpose of energy recovery is achieved.

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...
