MinusK LC-4超紧凑型隔振器


Low frequency vibration isolator for weight loads from 15 to 130 lbs. and 1/2 Hz performance vertical and horizontal.

Minus K’s LC-4 is an ultra compact, low-frequency negative-stiffness isolator. It comes in two configurations, our low horizontal frequency performance of 1.5 Hz or our ultra low horizontal frequency performance of 0.5 Hz. Both configurations offer our signature 0.5 Hz vertical natural frequency.

The LC-4 isolators can be combined into multi isolator systems to support heavier payloads while taking up very little room themselves. The isolators are passive, manually-adjustable and require no air or electricity.

If needed, the LC-4 isolators can be customized to achieve user specific needs. Eg., different horizontal and vertical frequencies, damping, etc. They can also be made cleanroom and vacuum compatible.

Performance

  • Vertical natural frequency of 1/2 Hz or less can be achieved over the entire load range.

  • Horizontal natural frequency is load dependent. 1 1/2 Hz (low horiz. freq.) or 1/2 Hz (ultra low horiz. freq.) or less natural frequencies can be achieved at or near the nominal load.

  • See Performance for a typical transmissibility curve with 1/2 Hz natural frequency.



LC-4是一个超紧凑,低频负刚度隔振器,可以组合成多个隔振器系统,以支持更大的有效载荷,同时占用很少的空间。 隔振器是被动的,手动调节,不需要空气或电力。
