Research on active vibration isolation for the active support mirror of space telescope

Space telescopes, free from atmospheric disturbances, possess higher resolution, making them a focal point of research in the scientific community. However, during the launch of space telescopes, vibrations can cause irreversible damage to the primary mirror. Passive damping methods are more effective in reducing high-frequency vibrations but less so for lowfrequency vibrations. In order to effectively suppress the transmission of low-frequency vibrations, this study designs an active vibration reduction system for space telescopes, tests the relevant performance of the system's key component - the permanent magnet spring-driven actuator, and evaluates the vibration reduction effect of the active vibration reduction system. The results indicate that after the introduction of the active vibration reduction system, the amplitude of lowfrequency vibrations in the experimental system decreases by 49.4% to 56.1%.
