Abstract:
A high frequency flexure-based dynamometer for measuring vibrations to use in determining cutting forces in a tool is disclosed. The dynamometer device may operate within a pre-selected high frequency range while measuring cutting forces less than about 1 N. The dynamometer may include two coupled flexures that interact to produce vibration modes at the edge of a selected bandwidth of interest. These modes may produce a frequency response function within the desired frequency band that has a magnified response and is substantially constant. The dynamometer may include a workpiece mounted to one of the two flexures and a one or more precision accelerometers mounted to the first or second flexures. Finite element analysis may be used to optimize the flexure design.
In-Situ Lubrication Of Sliding Electrical Contacts

International Classification:

US Classification:
508110, 508113, 508123, 508150, 310228
Abstract:
A method for in-situ solid lubrication of sliding electrical contacts includes the steps of providing a device having a movable electrically conductive first member and an electrically conductive second member, the first and second member being in electrical contact at a slideable electrical contact, and automatically applying an electrically conductive solid lubricant transfer film to the slideable electrical contact during operation of the device. The applying step can be a deposition of the electrically conductive solid lubricant transfer film on a surface of the first member, wherein the electrically conductive solid lubricant transfer film is carried by movement of the first member to the electrical contact.

Abstract:
A link of a vehicle suspension is elastic and includes three suspension points. A first point is adapted to be pivotally connected to a wheel carrier of the corresponding vehicle. A second point is adapted to be pivotally connected to a rigid chassis of the corresponding vehicle. The third point is adapted to be pivotally connected to a shackle, the shackle pivotally connecting the third point to the rigid chassis of the vehicle.

Abstract:
The present invention relates generally to deformation machining systems and methods that combine, in a single machine tool setup, the machining of thin structures and single point incremental forming (SPIF), such that novel part geometries and enhanced material properties may be obtained that are not achievable using conventional machining or forming systems and methods, individually or collectively. Important to many applications, lighter weight parts may be produced at lower cost using a conventional 3-axis computer numerically controlled (CNC) machine tool or the like, instead of the conventional 5-axis CNC machine tool or the like that is typically required.

Abstract:
A shear layer for a shear band that is used in a tire is provided that has multiple cells or units having an auxetic configuration and that are constructed from aluminum or titanium alloys. The cells may have an angle of −10.
Vibrations of rotary shafts, such as shafts of cutting tools used in high speed machining, are reduced by damping structures in holes in the shafts. The damping structures comprise fingers that are urged outwardly by centrifugal force due to rotation of the shafts and that slide relative to adjacent shaft surfaces due to shaft vibrations, so that vibrational energy is absorbed frictionally. Chatter, a self-excited vibration of a cutting tool, can be substantially reduced in this manner.
Micro-Molded Integral Non-Line-Of Sight Articles And Method

A method of forming integral articles having non-line-of-site contours includes the steps of providing a plurality of molds, the molds having at least one mold channel therethrough. The plurality of molds are stacked on one another to form a mold stack, wherein at least one portion of the mold stack provides a non-line of sight multi-level channel through at least partial overlap of the mold channels between adjacent ones of the plurality of molds. A flowable material is applied to the mold stack. The flowable material is pressed to fill the mold channels in each of the plurality of molds to form an integral article comprising a plurality of stacked integrally connected levels of the material, wherein through interconnection of the integrally connected levels the integral article provides at least one non-line of sight contour traversing in its thickness direction. The mold stack is then separated or removed to free the integral article.

Abstract:
Various embodiments provide a rotating electrical machine () that includes an electrical supply coupled to a stator (), a rotor (), and a plurality of roller elements (or brushes) () for transferring electrical current from the stator () to the rotor (). In one embodiment, each roller element () is compressed between the rotor () and the stator () so that outward forces resulting from expansive properties of each roller element () urge the roller element () into contact and maintain the roller element () in contact with the rotor () and the stator (). For example, in one embodiment, each roller element () has a hollow, substantially cylindrical body formed of a conductive material that is elastically biased in a radially outward direction to maintain contact with the rotor () and the stator ().
