Diagnosis device for space plasma parameters based on four-degree-of-freedom motion mechanism

Abstract

The invention discloses a space plasma parameter diagnosis device based on a four-degree-of-freedom motion mechanism. The device includes a probe array, a four-degree-of-freedom motion mechanism and a fixed frame, wherein: the four-degree-of-freedom motion mechanism is a four-axis structure , including two X-axes, one Y-axis and one Z-axis, each with a linear motion module; the probe array is mounted on the Z-axis of the four-degree-of-freedom motion mechanism and can rotate around the X-axis 90 degrees; the fixed frame is composed of a welding fixed plate, a support column, a vertical adjustment mechanism, a horizontal adjustment mechanism and a reference plate; the four-degree-of-freedom movement mechanism is fixed on the reference plate through the X-axis bottom plate, and the Y-axis is fixed on the On the slider of the X axis, the Z axis is fixed on the slider of the Y axis. Through the combination of the probe array and the four-degree-of-freedom motion mechanism, the present invention realizes large-scale, arrayed, and multi-dimensional diagnosis of plasma parameters, and provides technical support for plasma physics research in near-Earth space.

Description

A space plasma parameter diagnosis device based on a four-degree-of-freedom motion mechanism technical field The present invention relates to a kind of simulation device of near-Earth space plasma environment, be specifically related to a kind of based on four degrees of freedom The space plasma parameter diagnosis device of the motion mechanism. Background technique In order to study the basic physical process of near-Earth space plasma, the commonly used method is to construct large-scale experimental equipment [0002] The simulation study was carried out on the ground. In the space plasma environment simulation device, the diagnosis of plasma is very important Only by obtaining large-scale, high-resolution, high-precision plasma parameter diagnosis can the plasma be accurately characterized The state and study of related physical phenomena. Among many diagnostic methods, probe diagnosis is one of the most basic diagnostic methods. It is capable of diagnosing ph...

Problems solved by technology

In addition, a large number of magnet coils are installed in the near-Earth space plasma simulation device, and their motion support mechanisms are connected to the vacuum chamber. The electromagnetic force of the magnet coils will be transmitted to the vacuum chamber through the motion support mechanism, resulting in deformation of the vacuum chamber.
