| 摘 要： | 本文把倒摆和普通无源隔振系统按一定方式结合起来，设计出一种新型的低频无源垂直隔振系统。该系统由于负弹性系数的出现，使系统的等效弹性系数明显地减小，从而导致系统的共振频率有效地降低。理论分析表明，选择合适的参数，该系统能有效地抑制地面的干扰，其隔振效果从低频至高频区域明显地比普通无源隔振系统好得多，并且系统的权限共振频率也比普通无源隔振系统的极限共振频率显著地减少。

| Abstract: | A new low-frequency vertical vibration isolation system, which is constructed with a reverse pendulum and a general, passive, vertical isolaion, is proposed in this paper. By analysing and calculating,we have the conclusions: First, the equivalent spring coefficience of the system is decreased effectively due to the arising of the passive spring coefficience, which results in the decreasing of the resonant frequence, And if some proper parameters are chosen, the perturbauce caused by the ground vibration can be controlled effectively, and then the system works much better than the general one. Third, the limited resonant frequency of the system is decreased much more than that of the general system. |
