When the astronauts are running on the astronaut treadmill for healthy exercise, their impact force will have serious disturbances on almost all the on-orbital science experiments. To solve this problem, a parallel passive vibration isolation system is designed for the astronaut treadmill. The proposed passive vibration isolation system can also restrain the high-frequency disturbance aroused from the astronauts' intra-vehicular activities. Based on the vibration isolation theoretical analysis, a 6-degree of freedom dynamic model of the passive vibration isolation is developed. And then different vibration isolation system layouts are designed and compared. By using the Matlab/Simulink tools, passive vibration isolation performances are analyzed with comparison. As a result, the vibration isolation system parameters are optimized to improve the isolation system's performance.
