  • In order to suppress infrared telescope astronomy disturbance caused by the satellite payload, it is needed to design vibration reduction device for the telescope. Therefor a viscous fluid damper used in space is designed, which could be sealed reliably and adapted to the space environment well. Firstly, a damping calculation model based on the theory of fluid mechanics is built. Then, the structure of the damper is designed, and parameters of the spring sheet which was a core component belonging to the damper, are optimized. A set of prototype was manufactured, and a finite element model of the vibration isolation system was created to get the system's first two models. Finally, the simulation results are compared with the experimental results. According to the analysis results, it can be seen that the damper's stiffness characteristics and damping characteristics can meet the design requirement. The theory analysis results coincide with the experimental results, which proves that the finite element model is precise and the prototype has guidance value in engineering design.
