  • Patent number: 11644081
    Abstract: A vibration isolator, system, and method for minimizing propagation of vibrations between structures are configured to decouple axial and lateral structural modes. The vibration isolator includes an axial flexural support that provides axial compliance relative to a central axis and a lateral elastomeric support that provides lateral compliance relative to the central axis. The axial flexural support and the lateral elastomeric support provide stiffness about the central axis. The vibration isolator includes a first mount coupled to a first external structure and a second mount coupled to a second external structure. The axial flexural support is coupled to the first mount and the lateral elastomeric support is coupled to the second mount and the axial flexural support. Using an axial flexural support and a lateral elastomeric support enables tuning of the structural modes in one axis while minimizing the effects to the structural modes in the orthogonal axes.

  • Patent number: 10816056
    Abstract: A vibration isolation device includes flexures and a multi-part mounting interface for coupling a frame that supports equipment to a structure. The flexures may include three pairs of flexures that allow movement in three orthogonal directions, to allow compliance and/or damp vibrations in the three directions. The flexures may surround the multi-part mounting interface, the parts of which are configured to move relative to one another. One of the parts of the mounting interfaces passes through another part of the mounting interface, such as in one or more holes in one of the interfaces. The device allows equipment mounted on the frame to be isolated from some or all of vibrations produced at the structure. In an example embodiment the vibration isolation system is used in mounting an optical sensor or device to an aircraft.
