Abstract
An isolator including a body having a wall with slots that extend through a thickness of the wall from an isolator exterior to an isolator interior; the isolator comprising a center of elasticity; the slots having a cut angle oriented as angled relative to a radial direction orthogonal with an axis of the isolator; and a damping material disposed within at least one of the slots.
Claims16
An isolator comprising:
- a body having a wall with slots that extend through a thickness of the wall from an isolator exterior to an isolator interior;
- said isolator comprising a center of elasticity;
- said slots having a cut angle oriented as angled along a radial direction orthogonal with an axis of the isolator, wherein said cut angle aligns an area moment of inertia of said isolator to obtain a predetermined stiffness in each of three axes of said isolator wherein the area moment of inertia is manipulated by a configuration of the slots such that all three linear orthogonal modes are located in predetermined frequency allocations and all three rotational orthogonal modes are located in the predetermined frequency allocations;
- and
- a damping material disposed within at least one of said slots.
