Industrial Blue Lasers

Published 2019-05-01 by Tech Briefs Media Group in United States

Industrial lasers are integrated into manufacturing and fabrication facilities around the world. Every moment, there is an industrial laser somewhere that is cutting, etching, or welding. But the energy from traditional industrial lasers is not absorbed well by copper, so using them for copper processing has been slow and produced inferior quality.

Nonferrous Metals Bundle

  • Professional Development
  • PD281944
Published 2019-04-24

Nonferrous materials are malleable, are non-magnetic, and have no iron content which gives them higher resistance to rust and corrosion. The following five on-demand courses are included in the Nonferrous  Metals bundle.  Each course is approximately one-hour in duration. See Topics/Outline for additional details.

Detection of Presence and Posture of Vehicle Occupants Using a Capacitance Sensing Mat

Clemson University-Rahul Prasanna Kumar, Yunyi Jia
Ford Motor Company-David Melcher, Pietro Buttolo
Published 2019-04-02 by SAE International in United States
Capacitance sensing is the technology that detects the presence of nearby objects by measuring the change in capacitance. A change in capacitance is triggered either by a change in dielectric constant, area of overlap or distance of separation between the electrodes of the capacitor. It is a technology that finds wide use in applications such as touch screens, proximity sensing etc. Drawing motivation from such applications, this paper investigates how capacitive sensing can be employed to detect the presence and posture of occupants inside vehicles. Compared to existing solutions, the proposed approach is low-cost, easy to deploy and highly efficient. The sensing system consists of a capacitance-sensing mat that is embedded with copper foils and an associated sensing circuitry. Inside the mat the foils are arranged in rows and columns to form several touch-nodes across the surface of the mat. The system segregates row and column capacitances from each other and computes their tensor product to generate grayscale capacitance-sensing images. The images are real-time pictorial representation of the capacitance of each touch-node. When the mat…

Consideration of Corrosion Behavior of Aluminum Wire at Crimped Terminal and Effective Anti-Corrosion Treatment

Fujikura, Ltd.-Takuya Kawaguchi, Keiji Fukaura, Yuki Nakamura, Makoto Mochizuki, Satoshi Otani
Published 2019-04-02 by SAE International in United States
The demand for weight reduction of vehicles is growing in compliance with CO2 emission control requirements. Also, demand for copper is on the rise with an increase in the number of electric vehicles because their motors and wiring require a lot of copper. This has raised concerns about higher copper prices and vehicle weight. Recently, attempts to reduce vehicle weight have been actively made by partially replacing copper with aluminum, which is lighter and less expensive. Although the use of aluminum wires on limited areas of some vehicles has already been reported, that on all areas has not been reported yet. The authors focus on reducing weight of wiring harnesses, which is about 20 kg per vehicle, and consider using aluminum instead of copper as the conductor of the electrical wires. One of the factors impeding the use of aluminum wires in wider areas is galvanic corrosion occurring at crimped terminals. Since aluminum causes galvanic corrosion when the metal is in electrical contact with a different metal in an electrolyte, it is essential to prevent…

A Computational Study of Crystal Orientation Effects on High Strain Rate Performance of Single Crystal Copper

Mississippi State University-Yucheng Liu, Yangqing Dou
Published 2019-04-02 by SAE International in United States
This paper presents a computational study to investigate effects of crystal orientations on plasticity and damage of copper crystal at atomic scale. In the present study, a single crystal copper model was created as a target, which was struck and penetrated by a single crystal nickel. Three orientations, single slip system [1 0 1, 1 2 -1, -1 1 1], double slip system [1 1 2, 1 1 0, 1 1 -1], and octal slip system [1 0 0, 0 1 0, 0 0 1], were applied to the copper crystal. Their effects on plasticity and damage behavior of the single crystal copper were studied and compared using molecular dynamics simulations. Modified Embedded Atom Method potentials were applied to determine the pair interactions between the copper and nickel atoms.
