Abstract

The invention relates to a multi-axis ultrasonic suspension device and a control method. The multi-axis ultrasonic suspension device includes: multiple ultrasonic transmitters and brackets used for installing the ultrasonic transmitters, and further includes a control device; each ultrasonic transmitter is used for generating a standing wave to enable a suspension object to suspend; negative polepins of the ultrasonic transmitters are all grounded; multiple output ends are arranged on the control device, and each output end is separately in electric connection with a positive pole pin of an ultrasonic transmitter, wherein the control device is used for controlling output waveforms of the ultrasonic transmitters according to parameters of the ultrasonic transmitters and a three-dimensionalsound field model, so as to change a position of the suspension object. The multi-axis ultrasonic suspension device uses multiple ultrasonic transmitters to generate standing waves to form a sound field to make the suspension object suspend and controls the output waveforms of the multiple ultrasonic transmitters respectively through the control device, so as to change the suspension position ofthe suspension object and realize multi-direction movements.

Description

technical field [0001] The invention relates to the technical field of acoustic levitation, in particular to a multi-axis ultrasonic levitation device and a control method. Background technique [0002] Acoustic levitation technology is one of the key technologies for container-free processing of materials under ground and space conditions. Compared with today's magnetic levitation technology, acoustic levitation technology is not limited by the conductivity of materials, and levitation and other operations are controlled separately. The use of acoustic levitation can realize the non-container treatment of various metal materials, inorganic non-metal materials and organic materials. [0003] At present, the common ultrasonic levitation device is a uniaxial ultrasonic levitation device, which can only realize the movement of the levitated object in one direction. Contents of the invention [0004] Based on this, it is necessary to provide a multi-axis ultrasonic levitation...
