運作原理:

MinusK®隔振器在低頻隔振方面採用了革命性的理念。垂直運動隔離由支撐負重的剛性彈簧與負剛度機構（NSM）結合提供。在不影響彈簧的靜態負載支撐能力的情況下，使其淨垂直剛度非常低。與垂直運動隔離器串聯的樑柱可提供水平運動隔離。樑柱的水平剛度通過“樑柱”效應而降低。

MinusK®隔離器通常使用三個串聯的隔離器：傾斜運動隔離器在水平運動隔離器的頂部，垂直運動隔離器的頂部。垂直運動隔離器如圖1所示。它使用傳統的彈簧連接到NSM，該彈簧由兩個在其內端連接到彈簧並在其外端支撐的撓曲組成，並在力P的作用下承受壓縮力。彈簧的重量W壓縮到隔離器的工作位置，如圖1所示。隔離器的剛度為K = K S -K N其中K S是彈簧剛度，而K N是負剛度的大小，它是撓曲和載荷P的函數。在彈簧支撐重物W的情況下，可以使隔離器剛度接近零。

圖3圖1示出了結合有圖1和圖2的隔離器的負剛度振動隔離器的示意圖。傾斜墊用作傾斜運動隔離器。垂直剛度調節螺釘用於調節負剛度撓曲上的壓力，從而改變垂直剛度。垂直負載調節螺釘用於通過升高或降低支撐彈簧的底座來調節重量變化，以將撓性件保持在其筆直的，未彎曲的操作位置。該功能可以在單隔離器系統中實現自動化，並在多隔離器系統中實現自動調平。

圖4是典型的懸臂水平運動撓性件的示意圖，該撓性件允許較低的隔離器高度和較低的水平固有頻率。彎曲件在其端部承受重量載荷  W ，具有  x  和  y  位移能力。

1 - Vertical vibrations are isolated by the spring's interaction with four pairs of flexures. The weight of the instrument compresses the pre-loaded spring, floating the isolator and aligning the flexures.

2 - A squeeze force from another spring, controlled by the knob O. is applied to the outside of the flexures via a screw. The "squeezed" flexures constitute a "negative stiffness mechanism" (NSM) that acts like the negative of a spring, reducing the stiffness of the system.

3 - Four beam-columns connecting an upper and lower column plate act as a horizontal spring to isolate the horizontal motion. The beam-columns are vertically very stiff, but bend slightly in response to horizontal vibration. The weight on the deflected beam-columns reduces the stiffness of the spring, making the system behave like a spring with an NSM.

4 - The crank moves the base of the spring up and down to compensate for changes in the weight of the payload and to keep the flexures in their straight aligned position. If you increase the weight on the spring (by swapping a lighter microscope for a heavier one, for example), its base must be raised by turning the crank clockwise.
