Space mass measurement device by utilizing sensing property of ferromagnetic droplets in gradient magnetic field

Abstract

The invention provides a space mass measurement device by utilizing the sensing property of ferromagnetic droplets in a gradient magnetic field. A rotating shaft is divided into an upper portion and a lower portion which are respectively connected with the upper side and the lower side of a coil housing, the upper end of the rotating shaft is connected with a motor to produce rotational movements, the coil housing wraps a whole coil, an excitation maintaining coil is arranged on a coil support sleeve in a winding mode and evenly wound around the whole coil support sleeve, and two testing coils are arranged on the excitation maintaining coil in a winding mode, the testing coils are in axial symmetry with the coil support sleeve. An end cover is mounted at the left end of the coil support sleeve, an end cover is mounted at the right end of the coil support sleeve, a small hole is formed in each end cover and can be used for placing a ferromagnetic droplet module, a plastic ball or a glass ball of each ferromagnetic droplet module and one part of each of long rods at two ends are located in an inner sleeve, the other part of each of the long rods at the two ends are exposed outside the inner sleeve, two ends of the long rods are respectively pass through small holes in two ends of the inner sleeve and extends outside the inner sleeve, and a weight measuring box is in rigid connection with the long rod at the right end. The space mass measurement device by utilizing the sensing property of the ferromagnetic droplets in the gradient magnetic field can be used for measuring the small of an object in a weightless state in space.

Description

technical field [0001] The invention relates to a space mass measurement device, especially a device mainly used for measuring the mass of objects in a space microgravity environment, and specifically relates to a space mass measurement device utilizing the sensing characteristics of ferromagnetic liquid droplets in a gradient magnetic field. Background technique [0002] With the development of space technology, human exploration of space has become more and more in-depth. When conducting experiments in space, mass is an important measurement item. Under normal circumstances, if you want to measure the mass of an object on the earth, you basically use the gravity method, such as a spring balance. However, these methods will fail in the environment of weightlessness in space or uneven distribution of gravitational acceleration in alien planets, so it is very important to find a method that can measure the mass of objects in a space environment. [0003] In order to measure...
