US Patent:

6389900, May 21, 2002

Filed:

Oct 17, 2000

Appl. No.:

09/690607

Inventors:

Theodore Leist - Middletown OH
William M. Rusen - Fairlawn OH
Edward L. Peterson - Hudson OH
Richard E. McCormick - Bay Village OH

Assignee:

MB Dynamics - Cleveland OH

International Classification:

G01M 700

US Classification:

73662

Abstract:

Flexure assemblies include steel plates or pieces of metal material that are rigid in at least one direction but flexible in at least one other direction. One arrangement of components provides a flexure assembly that is intended to permit linear motion along an axis while preventing off-axis motion. Another arrangement of components permits rotary or pivotal motion about an axis within a limited range while preventing off-axis motion. All arrangements provide a frictionless and noiseless support arrangement that is well suited for test equipment where noise sensitivity and accuracy are of concern. The invention provides a testing device that permits test forces to be input directly to a vehicle body structure for testing vehicle squeak and rattle noises within a vehicle interior.

International Classification:

B65G 1/00

US Classification:

414286, 41433101, 414807

Abstract:

Storage and retrieval systems and methods are provided to automate the process of handling a mixed inventory of palletized and containerized items. In one embodiment, the stowage and retrieval system comprises a storage area comprising a plurality of stationary cell modules arranged in a matrix, wherein each cell module comprises at least one motor. The system also comprises a plurality of carriers comprising at least one magnet disposed on an underside of each of the carriers and at least one engagement mechanism disposed on a top side of each of the carriers. The at least one magnet of the carrier is configured to engage the at least one motor of a corresponding cell module, and the at least one motor is configured to move the carrier within the storage area.

Inventors:

Jack M. Thompson - Milford OH
Theodore H. Leist - Bethany OH

Assignee:

Structural Dynamics Research Corporation - Milford OH

International Classification:

B06B 110

US Classification:

73663

Abstract:

A seismic testing apparatus is provided in which linear motion or excitation of a horizontally disposed table is achieved simultaneously along three mutually orthogonal axes by means of independently operable hydraulic-actuator assemblies. Rotational or torsional motion of the table about the linear excitation axes is resisted by separate, mechanical rotation-inhibiting means each consisting of a torsionally rigid structure disposed parallel to the table and perpendicularly to their respective associated axes of excitation. The torsionally rigid structures are each connected to the table at two spaced-apart points, with all four points of connection lying in the same plane.

MB Dynamics - Cleveland OH

International Classification:

G01M 700

US Classification:

73662

Abstract:

A flexure assembly that is particularly useful in vibration testing equipment provides a noiseless, frictionless support that allows motion in a desired direction while restricting motion in other directions. The flexure assembly includes a flexure arm that is made from a material that is at least partially flexible in one direction while being stiff in at least two other directions, which are generally perpendicular to the one direction. A first end of the flexure arm is adapted to be rigidly secured to a moving portion in a vibration testing device, for example. A second end of the flexure arm is rigidly secured to a mounting block. The mounting block is also rigidly secured to two flexure leaves, which are also made from a material that is at least partially flexible in one direction while being stiff in at least two other, generally perpendicular, directions. A second end of the flexure leaves are rigidly secured to a second mounting block, which is adapted to be secured to a base within a vibration testing device, for example. The flexure arm and flexure leaves preferably are made from stainless steel and are generally planar and generally rectangular.
