A novel design allows column springs in Euler buckling mode to be laterally stable and thus provides vibration isolation in six degrees of freedom. Analytical models of the stiffness were used to develop a design with a vertical resonance of 1.13 Hz, a horizontal resonance of 1.68 Hz, and a roll resonance of 2.58 Hz. A prototype vibration isolator reduces vertical vibration by a factor of 2 at 2 Hz. Vertical, horizontal, and roll vibrations are reduced by a factor of 100 at frequencies above 20 Hz.
一种新颖的设计使处于欧拉屈曲模式的柱形弹簧具有横向稳定性，从而提供六自由度的隔振效果。利用刚度分析模型开发出一种设计，其垂直共振频率为1.13赫兹，水平共振频率为1.68赫兹，滚动共振频率为2.58赫兹。一个隔振器原型在2赫兹时可将垂直振动降低一半。在20赫兹以上的频率下，垂直、水平和滚动振动可降低100倍。
