Active vibration isolation system applied to microgravity vibration isolation has utilized Lorentz force electromagnetic actuator to realize the levitation of isolated platform in the space. The Dynamic Analysis of the Electromagnetic Actuator (DAEA) is the basis of design and experiments. In this study, a structure of the actuator was presented, the finite element analysis of the permanent magnet part was implemented and the mechanical feature was validated. With the establishment of electromagnetic actuator model, the finite element analyses have been conducted, which includes static force feature analysis, implement modal analysis, transient analysis, harmonic response analysis and spectrum analysis as well. These analyses have paved the way for system structure optimization and actuator size reduction as to decrease the development cost, shorten the designing period and promote the product quality.
