标题：Research on the Vibration Characteristics of the New Type of Passive Super Static Vibratory Platform Based on the Multiobjective Parameter Optimization
摘要：In order to reduce impact on payload due to vibration, the new type of passive super static vibratory platform and its dynamic mathematical model were established. In order to obtain the best performance of this platform, the method of multiobjective parameter optimization was applied to decide the parameters such as stiffness coefficient and damping coefficient. Then studying the dynamics inherent characteristic of the platform, the result shows the new type of passive super static vibratory platform has relatively low natural frequency and can effectively reduce the vibration of the high frequency range that means this new type of passive super static vibratory platform was suitable for the satellite payload work environment. Based on the simulation, the experimental platform was manufactured and tested on the platform with random forced vibration; the result shows the new type of passive super static vibratory platform has an obvious vibration damping effect.
