Abstract

The invention relates to a method and a device for measuring suspension force in an ultrasonic suspension machine and belongs to the field of measuring. The device can be divided into two parts: a lever balancing part and a force measuring part, through the lever balancing part, measuring of acoustic suspension force can be converted into measuring of supporting force of a weighing sensor, through the force measuring part, the supporting force applied to a small ball 4 by the weighing sensor can be measured, and a specific numerical value of the acoustic suspension force can be obtained according to the lever principle. The method and the device for measuring ultrasonic standing wave suspension force have the advantages of high accuracy (depends on measuring accuracy of the weighing sensor), low cost, simple structure and easiness in operation, the acoustic suspension force applied to small balls of different sizes at any position between ultrasonic emitting end and a reflection adjusting end can be measured.

Description

technical field

[0001] The invention relates to a method and a device for measuring the standing wave suspension force in an ultrasonic suspension device, belonging to the field of measurement. Background technique

[0002] Because the space environment has remarkable characteristics such as no container, microgravity, and high vacuum, it is beneficial to study the solidification and fluid phenomena of materials, so the space environment is used for the preparation of materials and various experiments. In the past few decades, although aerospace technology has developed rapidly, the cost of conducting space experiments is still very expensive. Therefore, the levitation technology that simulates space without container effect on the ground came into being. Acoustic levitation technology is one of the levitation technologies that can realize material container-free processing under ground and space conditions. Compared with other levitation technologies, acoustic levitation h...
