Three-dimensional magnetic induction intensity measurement coil for ultra-high-speed collision magnetic field

Abstract

The invention discloses a three-dimensional magnetic induction intensity measurement coil for an ultra-high-speed collision magnetic field, and belongs to the technical field of measurement of impact dynamics. The measurement coil comprises a spherical frame and three annular coils, wherein the spherical frame is in a sphere shape, three annular grooves which are perpendicular to one another are formed in the surface of the spherical frame in the radial direction, the depths of the three annular grooves decrease in sequence, the three annular coils wind the three annular grooves correspondingly and are independent of one another, each coil is connected with one BNC plug, and the BNC plugs are connected with three external data collection channels which are independent of one another. The three coils which are perpendicular to one another spatially are adopted to obtain the magnetic induction intensity of a certain spatial point in three directions, the magnetic field information of a measured point is known comprehensively, and interference and errors for research of the collision magnetic field are avoided; the measured coil induction electromotive force signals are synchronous in time, and a measurement result is more accurate. The three-dimensional magnetic induction intensity measurement coil for the ultra-high-speed collision magnetic field is simple in design, easy in operation and capable of being recycled.

Description

technical field [0001] The invention relates to a measuring device for measuring the magnetic field generated by ultra-high-speed collisions, and belongs to the technical field of impact dynamics testing. Background technique [0002] The high-speed impact of space debris on the spacecraft has caused many spacecraft accidents. Studies have shown that the damage to the spacecraft caused by the ultra-high-speed impact of space debris is not only the mechanical damage caused by the mechanical failure of the internal structure of the spacecraft caused by the strong impact, but also the collision. The damage caused by the electromagnetic effect caused by the interference of the spacecraft's internal circuit system. [0003] When carrying out experiments to study the characteristics of the electromagnetic field generated by ultra-high-speed collisions, in order to obtain the intensity value of the magnetic field generated by the collision at a certain point in space, due to its sm...

AI Technical Summary

Problems solved by technology

However, the commonly used disc coil can only measure the magnetic induction intensity value in the direction perpendicular to the coil plane, and cannot identify the magnetic field component in the direction parallel to the coil

In this way, the understanding of the magnetic field information at this point will be incomplete, which will interfere with the research, or there will be errors in the conclusion
