Abstract

The suspension test system within the high microgravity scientific experiment cabinet is equipped with double-layer vibration isolation, effectively isolating external disturbances and creating a high microgravity environment within the inner body. Based on this characteristic, this paper proposes a double-layer plane air platform ground test system design. By using a high-precision acceleration sensor and gyroscope of the suspension test platform, the system coordinates the measurement of the double-layer air floating platform. The control mode and algorithm for double-layer vibration isolation in the suspension test platform are simulated through ground physics. Ground verification results from the double-layer plane air flotation test system show that the double-layer attitude control hardware of the suspension test platform meets the requirements, and the algorithm control effect is good, which provides sufficient experimental evidence for the normal operation of the suspension test system in orbit.
