Background technology
Acoustic levitation technique is the crucial skill realizing material solvent-catalyst free under ground and steric requirements
One of art, compares with electromagnetic suspension technology, and whether it is not limited by materials conductive, and suspends
Control respectively with heating, thus may be used to study nonmetallic materials and low-melting alloy without container
Solidification, now, people can pass through acoustic levitation method, it is achieved various metal materials, inorganic non-
Metal and the solvent-catalyst free of organic material, carry out droplet dynamics, material science, analysis
The research of the aspects such as and biochemistry, acoustic levitation is the non-linear effect of the one under the conditions of high sound intensity
Should, its ultimate principle is to utilize sound standing wave to produce the suspension of vertical direction with interacting of object
Power is to overcome the weight of object, and the detent force simultaneously producing horizontal direction secures the object to acoustic pressure
At node, acoustic levitation technique is divided into triple axle and single axle two kinds, and the former in three, space is just
Handing over direction to excite string standing wave to control the position of object respectively, the latter only produces at vertical direction
String standing wave, the sound field of the certain pattern that its suspension detent force is excited by cylindrical cavity is come
There is provided, acoustic levitation be mainly characterized by the electromagnetic performance of sample is not had particular/special requirement, suspend relatively
Stable, it is easily controlled, electromagnetic suspension requires that sample can conduct electricity, and electrostatic suspension then needs examination
Carried charge and the suspended voltage of sample accurately control, and pneumatic suspension lateral stability is poor, light
The size of suspension sample is generally below 150 μm.
