In order to solve the discordance between the engineering calculated natural frequency and the experimental natural frequency of the air-spring precision isolation system, the dynamic models of the air-spring isolation system were established and the engineering calculated natural frequency was 1.28Hz based on an isolation system. Then, impact experiments were carried out in lab and the experimental natural frequency was 1.22Hz using FFT method. The relative error between the two was less than 5%, which reached the expectations, and the error sources were briefly analyzed. The results of the research in this paper have reference value in designing and manufacturing of the air-spring precision isolation systems.
