本文尝试采用磁流体阻止隔振装置承载台面的运动。利用非磁性体在磁流体的悬浮力,设计了内筒与外筒之间没有刚性接触的活塞型阻尼器。通过一系列实验测定隔振装置的性能,并得到这种隔振装置能隔离大地的干扰振动和能有效地抑制共振的结论。 This paper attempts to use magnetic fluid to prevent the vibration isolation device bearing table movement. By using the levitation force of the non-magnetic fluid in the magnetic fluid, a piston type damper with no rigid contact between the inner cylinder and the outer cylinder is designed. Through a series of experiments, the performance of the vibration isolation device was measured and the conclusion was obtained that the vibration isolation device could isolate the disturbing vibration of the earth and effectively suppress the resonance.
