Embodiment Construction

[0016] This device is a measuring device for ultrasonic levitation force, and its structure refers to figure 1 and figure 2 . The beam 8 is placed on the knife seat 9, the knife seat 9 is fixedly connected to the base 7, the threaded rod 5 and the thin rod 13 are all fixed on the cross beam 8, and the leveling nut 6 can rotate left and right on the threaded rod 5 through threaded connection, The small ball 4 and the small ball 16 are threadedly connected with the threaded rod 5 and the thin rod 13 respectively, and the height of the load cell 3 is adjusted by adjusting the liftable support platform 2, and the load cell 3 is in contact with the small ball 4. There is no effect of force. In this way, a complete ultrasonic levitation force measuring device is formed.

[0017] When using this device to measure the ultrasonic standing wave suspension force, the specific steps are as follows:

[0018] 1. Place the small ball 16 between the ultrasonic transmitting end 17 and the...

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...
