Top Takeaways from SAE

What were people talking about at the SAE World Congress? EASi representatives share their top takeaways.

SAE International recently hosted its annual World Congress, with an agenda covering the latest developments in automotive engineering and manufacturing. Highlights of the event included seminars on new trends and products, as well as the presentation of a technical paper by EASi and Ford Motor Co. on new methodology for seat design.

Many of the seminars and exhibits were clearly focused on one trending topic: autonomous and electric vehicles:

OEMs: Original equipment manufacturers (OEMs) were keen to showcase their investments in AV. GM featured the Bolt, which is going to be out in the market soon. Ford shared its smart mobility solutions model.

Dashboard systems: Consumers are coming to expect the user-automobile interface to anticipate their needs and make the driving experience simple and efficient, keeping the focus on embedded systems.

Project management: Automation isn’t just transforming the manufacturing process, it’s also gaining use via techniques in report generation that saves hours of manual toil.

Parts and services: There were more suppliers from the AV technology side this year than in past years, including those who write code and make software for 3D printing and manufacturing, and those who promote the application of composite materials in auto interiors.

Resources: More engineers at SAE seemed to be looking to change careers and join the autonomous industry. Attendees with years of experience working as product engineers in powertrain were interested in learning more about AV. Attendees also exhibited interest in finite element analysis (FEA) and computational fluid dynamics (CFD).

New technical paper

Also at the event, EASi and Ford Motor Co. presented a new technical paper on automotive seat design. Here is the abstract:

CAE Methodology for Seat Assessment with H-Point Machine 2018-01-1322

Seat assessment is an important necessity for the growing auto industry. The design of seats is driven by customer’s demand of comfort and aesthetics of the vehicle interiors. Some of the few seat assessments are H-point prediction with H-point Machine (HPM); backset prediction with Head Restraint Measuring Device (HRMD); seat hardness and softness.

Traditional seat development was through developing series of prototypes to meet requirements which involved higher costs and more time. The seat requirement of H-Point measurement is of focus in this paper. Though there are other commercial available software/methods to perform the H-point measurement simulations, the aim here was to assess the capabilities of an alternate Computer Aided Engineering (CAE) methodology using CAE tools - PRIMER and LS-Dyna. The pre-processing tools —Hypermesh and ANSA have been used for modeling and Hyperview tool used for reviewing the simulations.

The CAE results show good correlation to test results and compare well to other commercial software/methods. This methodology has been beneficial in developing seat designs in the early development cycle much before the final prototype testing.
