Method of supporting tubing structures during overcasting

Номер: US20120152481A1
Автор: Joshua D. Lasceski, Michael J. Walker
Принадлежит: GM GLOBAL TECHNOLOGY OPERATIONS LLC

A method of supporting a metal tube during an overcasting process includes radially supporting the metal tube from within an interior opening of the metal tube with a compressed granular material. The compressed granular material is held in place by a first stop and a second stop positioned at opposite axial ends of the metal tube. A tensile connector, such as a rod or a cable, interconnects and attaches the first stop and the second stop. Compressive radial forces exerted onto the metal tube during the overcasting process are transferred through the granular material and resisted by a tensile force in the tensile connector.

DRY FRICTION DAMPED MECHANICAL AND STRUCTURAL METAL COMPONENTS AND METHODS OF MANUFACTURING THE SAME

Номер: US20180073588A1

Принадлежит:

A method and system for increasing damping capacity in cast metal parts by utilizing dry friction between individual wires of a sheathed rope is disclosed. The rope is embedded into the part during casting. Sheathing the ropes in a thin layer of the same metal as the casting prevents molten metal from infiltrating individual wires during casting, thus allowing inter-wire friction during the part vibration. There are two ways to distribute the ropes within a part during casting. The first way is to distribute the ropes uniformly across an entire part whereby damping capacity of the metal part increases uniformly as well. The second way of distributing the ropes is to spatially distribute them according to a pattern to increase the damping capacity only in the part regions that have the highest vibration amplitudes or stress during system vibration. Both methods of distribution may be combined in a single part. 1. A vibration-dampener for use in a cast metal component comprising:a rope having first and second ends, said rope comprising a plurality of wires positioned next to one another; anda metal sheathing encasing said plurality of wires to form said rope, said sheathing having a melting point equal to or greater than the casting alloy, whereby sliding movement of the surfaces of the wires relative to one another dampens resonant vibration of the component.2. The vibration-dampener of in which said first end and second end are joined claim 1 , thereby forming a rope ring.3. The vibration-dampener of further including at least one locator tab attached to said rope and extending therefrom.4. The vibration-dampener of wherein said rope is formed within an insert which is cast in the cast metal component.5.

A method of producing a Metal Matrix Composite (MMC) with uniform surface layers is disclosed. First, a low volume fraction compressible discontinuous ceramic fiber paper is set on the base of a mold cavity. Next, an array of reinforcement preform(s) (1×1,2×2, 4×4, 2×8, etc) are set in the mold on top of the ceramic fiber paper. A top layer of ceramic fiber paper is next placed on the array of reinforcement preforms and the mold cover seals the mold. The reinforcement porous preform(s) are held to the center of the mold cavity when the sealed mold compresses the top and bottom layers of ceramic fiber paper. The ceramic fiber paper exerts an equal and opposite force on the reinforcement preform(s) within the closed mold centering the preform(s) within the mold cavity. The mold cavity is next infiltrated under pressure with molten metal allowing for metal to penetrate into any open porosity of the ceramic fiber paper, reinforcement preform(s), and areas within the mold cavity that contain open spaces. Subsequent to molten metal infiltration, the aluminum rich surface layers are equal thickness on both sides of the reinforcement preform(s).
