Passive structures with high stiffness and high damping properties
A passive structural system includes a structural element which may be subjected to energy which gives rise to vibration in the element. At least one bi-stable sub-structure is coupled to the element. Each bi-stable sub-structure has two stable equilibrium states between which the sub-structure can physically transition when subjected to a sufficient amount of energy which gives rise to vibration in the element, with each bi-stable sub-structure arranged to dissipate at least a portion of the energy and thereby damp the vibration in the structural element when it transitions from one equilibrium state to the other. The passive structural system may also be intentionally mistuned such that when subjected to energy which gives rise to vibration, the vibration energy is substantially confined to localized regions within the system. The bi-stable structures are then located in the localized regions and arranged to dissipate the localized vibration energy.
