In large scale industries attempts are continuously being made to automate assembly processes to not only increase productivity but also alleviate non-ergonomic tasks. However this is not always technologically possible due to specific joining challenges and the high number of special-purpose parts. For the riveting process, for example, semi-automated approaches represent an alternative to optimizing aircraft assembly and to reduce the exposure of workers to non-ergonomic conditions entailed by performing repetitive tasks.In [1], a semi-automated solution is proposed for the riveting process of assembling the section barrel of the aft section to its pressure bulkhead. The method introduced a dynamic task sharing strategy between human and robot that implements interaction possibilities to establish a communication between a human and a robot in Human-Robot-collaboration fashion. Although intuitive, interacting with the robot constantly is still not natural for the worker as in the manual process no explicit communication between both workers is needed.In this work a communication-free Human-Robot-collaboration solution is presented. The method developed not only enables sharing assembly missions by dividing tasks based on skills, but…

Rethinking aluminum for NVH abatement

Automotive Engineering: June 2019

Published 2019-06-01 by SAE International in United States

Engineers, abandon those mastics! New “quiet” materials solutions are at hand.

Engineers who have witnessed aluminum-intensive vehicles being “uncloaked” in a full competitive teardown relate the same story: After you've pulled the carpet out and stripped it down to the naked bodyshell, the “band-aids” are clearly exposed-typically on the floorpan, bulkheads, on the rear package tray of sedans, around the wheelhouses, and within the noise-critical dash panel and cowl plenum.

Structural Optimization of a Pickup Frame Combining Thickness, Shape and Feature Parameters for Lightweighting

SAE International Journal of Materials and Manufacturing

AK Steel Corporation-Jianyong Liang, Jonathan Powers, Scott Stevens
  • Journal Article
  • 05-11-03-0018
Published 2018-08-08 by SAE International in United States
The methods for improving the torsion stiffness of a pickup chassis frame were discussed, including increasing the part thickness on frame, enlarging the cross section of rails, and adding bulkhead feature inside the rails. Sizing optimization was conducted to get the optimal thickness configuration for frame parts and meet the siffness requirement. The cross section of frame rails was parameterized and shape optimization was conduted to get the optimal rail cross sections for stiffness improvement. Additional bulkheads were added to the frame rails, and sizing optimization conducted to find the most effective bulkheads to add and their optimal gauge. A material efficiency ratio μ is used to evaluate the efficiency of a design change with respect to torsion stiffness. Among those torsion improvement methods, adding bulkhead feature gives the highest material efficiency ratio, but the stiffness improvement is very limited. Enlarging the rail sections and increasing the part thickness can improve the torsion to over 9% while the material efficiency ratio is relatively low. Simultaneous structural optimization was conducted combining above two and all torsion…
