  • Patent number: 6325351
    Abstract: A highly damped kinematic coupling for precision instruments. The kinematic coupling provides support while causing essentially no influence to its nature shape, with such influences coming, for example, from manufacturing tolerances, temperature changes, or ground motion. The coupling uses three ball-cone constraints, each combined with a released flexural degree of freedom. This arrangement enables a gain of higher load capacity and stiffness, but can also significantly reduce the friction level in proportion to the ball radius divided by the distance between the ball and the hinge axis. The blade flexures reduces somewhat the stiffness of the coupling and provides an ideal location to apply constrained-layer damping which is accomplished by attaching a viscoelastic layer and a constraining layer on opposite sides of each of the blade flexures.

    Abstract: A system is described which utilizes two perpendicular four-bar linkages coupled by a common plate to provide a translational-free flexible suspension having two rotational degrees of freedom about a desired point. One of the four-bar linkages is secured to a stationary "ground" structure, and the other linkage is attached to the object to be supported, such as a mirror. In one embodiment, two links of each of the two four-bar linkages are constructed from spring steel flexure elements which are rigid in all directions except about the rotational axis. The flexure elements thus comprise "revolute joints". Because the flexure elements function as spring hinges, no friction is encountered when the suspension is displaced or "pivoted".

  • Patent number: 5305981
    Abstract: A system for isolating a supported structure from transmitting vibrations to a supporting base in a spacecraft provides six degrees of freedom in a kinematic mounting. Six isolator elements in a symmetric arrangement of three skewed isolator pairs provides viscous damping and vibration and shock attenuation during launch and operation in space. The isolators employ two degrees of freedom flexure joints at each mounting point to assure primarily axial deflection and minimize bending moments, and have tuning springs to optimize performance. The system permits deterministic design and allows calculation of all loads from the nominal geometry and the isolator axial stiffness. Limit stops are provided between the supporting structure and the supported structure to limit excursions of the isolator members.

  • Patent number: 5005671
    Abstract: An apparatus for isolating horizontal shocks, generated in high speed elevators by inaccurately aligned guide rails, from the elevator car body includes spherical shock absorbers for supporting the bottom side of the car body in a car sling and centering elements with cooperating guide pins connected between the top side of the car body and the car sling. The lower portion of the car body can, in the case of horizontal shocks, execute a rolling deflection movement on the spherical shock absorbers to absorb these shocks. This deflection movement takes place against a centering spring tension, which is produced by a centering device attached to the bottom side of the car body and a guide pin extending through a guide sleeve of the centering device which pin is moved by the car body into an inclined position. An elastic filler element produces a centering counterforce on the upper portion of the guide pin.
