Abstract
Official abstract text for this publication.
A variable stiffness structure configured to isolate a mass from unwanted vibrations includes a negative stiffness element and an actuator operatively coupled to the negative stiffness element. The actuator is configured to be actuated to control a stiffness of the negative stiffness element. The variable stiffness structure may also include a positive stiffness element coupled to the negative stiffness element.
First claim
Opening claim text (preview).
What is claimed is: 1. A vehicle, comprising: a vibration isolation system comprising: at least one variable stiffness structure, the at least one variable stiffness structure comprising: a negative stiffness element; and an actuator operatively coupled to the negative stiffness element to control a stiffness of the negative stiffness element; and a payload supported on the negative stiffness element; and a first sensor coupled to the actuator, the first sensor configu…
