被动式减振系统 Passive vibration isolation system
Generally, passive vibration isolation is effective only when the frequency of disturbance is higher than 20-30Hz due to its limited wide band vibration isolation, so it can not meet the requirement of high isolation rate of long-focus systems.
一般被动减振只能抑制高频扰动20-30HZ以上的问题,其宽频带隔振效果十分有限,不能满足长焦系统的高隔离度的要求。
