摘要：
According to the vibration differential equation of cantilever, and the continuum equation of fluid, two kinds of magnetic fluid dampers mainly used in spacecrafts were designed. It is proved that different shape of damper, different diameter of permanent magnetic, different saturated magnetization intensity of magnetic fluid and different quantity of magnetic fluid have influences on the damping performance based on the experiments for comparing the time duration for vibration vanishing. It is also concluded that the diameter of permanent magnetic, saturated magnetization intensity of magnetic fluid and quantity of magnetic fluid own their optimal values at different vibration frequency. The results provide the base for structural optimization of magnetic fluid dampers which could be of great significance for the design of spacecrafts with low frequency and small amplitude vibration. © 2017, Editorial Office of Journal of Vibration and Shock.
