AI Technical Summary
In a vacuum environment, commonly used structures and sensors are affected by the vacuum, resulting in a decrease in detection sensitivity. At the same time, the performance of the structure in different gravitational directions must be considered.
By using a combination of electromagnets and magnetic blocks, the magnetic attraction force is adjusted by the current of the electromagnet to realize the opening and closing movement of the fixed and rotating test frame. The direction of gravity of the test frame inside the vacuum chamber is changed by adjusting the support mechanism. The change of magnetic attraction force is measured by a laser generator and a receiver, thus avoiding the use of vacuum-specific sensors.
Accurately measuring the minimum torque requirements of fixed and rotating test fixtures in a vacuum environment enables motion testing under different gravitational directions, improving detection sensitivity and accuracy.
