Abstract

The invention provides a ground simulation test attitude adjusting mechanism for a space detection sensor. The y-axis is defined as the horizontal direction and the z-axis is defined as the vertical direction. The adjusting mechanism comprises a rotating support around the y-axis, a rotating support around the z-axis, a y-axis revolving pair, a z-axis revolving pair, a sensor support and a rack platform. The connection relation of the attitude adjusting mechanism is that the sensor support is fastened on the rotating support around the y-axis and parallel to the z-axis, the rotating support around the y-axis is connected with the rotating support around the z-axis through the y-axis revolving pair, and the rotating support around the z-axis is connected with the rack platform through the z-axis revolving pair; and the sensor support is used for installing the space detection sensor, and the central axis of the y-axis revolving pair penetrates through the center O of the space detectionsensor, and the central axis of the z-axis revolving pair penetrates through the center O of the space detection sensor. The sensor position can be guaranteed to be unchanged when the sensor attitudeis adjusted.

Description

technical field [0001] The invention relates to a ground simulation test attitude adjustment mechanism of a space detection sensor, belonging to the technical field of space detection load ground tests. Background technique [0002] In order to explore the changing law of the space electric field, the space electric field detection sensor is placed in the plasma simulation equipment with a magnetic field applied on the ground for experiments. The distribution of plasma in the ground plasma simulation equipment is different in the axial and circumferential directions, so the sensor needs to be placed in the same position for multiple tests during the test; since the space electric field detection sensor is used during the on-orbit period with the satellite The adjustment of attitude is relative to the change of the direction of the magnetic field. This situation needs to be simulated in the ground plasma simulation equipment, but the magnetic field applied in the ground plasm...
