To be published on 2019-09-16 by SAE International in United States
Accurate and fast positioning of large aircraft component is of great importance for Automated Alignment System. The Ball joint is a widely-used mechanical device connecting the aircraft component and Automated Alignment System. However, there are some shortcomings for the device in man-machine engineering, such as the entry state of the ball-head still needs to be confirmed by the workers and then switched to the locking state manually. To solve above problems, a new positioning mechanism is present in this paper, which consists of a ball-head and a ball-socket. The new device is equipped with a monocular vision system, in which a calibrated industrial camera is used to collect the images of the ball-head. And then, the 3-D coordinate of the ball-head center is calculated by a designed algorithm, which combines the symmetry of the sphere and the principle of projection transformation, guiding the positioner to capture the ball-head. Once the ball-head gets into the ball-socket, the pneumatic system inside the ball-socket will drive the piston to move to the specified location. Meanwhile, the amount of…

Heat Treatment of Carbon and Low-Alloy Steel Parts, Minimum Tensile Strength Below 220 ksi (1517 MPa)

AMS E Carbon and Low Alloy Steels Committee
  • Aerospace Material Specification
  • AMS2759/1G
  • Current
Published 2019-06-17 by SAE International in United States

This specification, in conjunction with the general requirements for steel heat treatment covered in AMS2759, establishes the requirements for heat treatment of carbon and low-alloy steel parts to minimum ultimate tensile strengths below 220 ksi (1517 MPa). Parts are defined in AMS2759. Due to limited hardenability in these materials, there are size limits in this specification.

The History of Laminated Steel

Antiphon/C&A/ AAP (retired)-Peter Jackson
General Motors (retired)-James Shedlowsky
Published 2019-06-05 by SAE International in United States
This paper discusses the background and history of “laminated steel” (commonly called “noiseless steel” or MPM). It provides the early development, where it came from, and how it was introduced to North America as a new tool for engineering acoustical solutions. A progressive timeline shows laminated steel from its earliest inception in Europe to its current role in today’s global market. Case histories along with examples of successful applications detail its important contribution in advancing the technology for component damping. Many manufacturing sources as well as end users have been impacted over the decades since it was first introduced. Some of those companies will be noted. The background information for this paper is provided by many of the individuals who were involved in the very early stages of its introduction as well those who are currently working to utilize the technology of laminated steel.

  • 19AUTP06_09
Published 2019-06-01 by SAE International in United States

Those playing in the global automotive field have to keep their eyes on various new ‘curve balls’ that are winding their way toward home plate. Among them are the ever-present trade ‘discussions’ surrounding the U.S.-China relationship, steel and aluminum tariffs and the ongoing instability of Brexit. Behind the scenes, however, another potentially more impactful force is building that will invariably alter the industry's trajectory: China's emergence as a major manufacturing base.
