Load Distribution Optimization of Seatbelt Using Validated Finite Element Approach

Anshul Satija-Anshul Satija
Joyson Safety Systems-Priyanshu Mishra, Ravi Gaurav, Virender Singh
  • Technical Paper
  • 2019-28-2575
Published 2019-11-21 by SAE International in United States
The seat belt system is one of most important component of the safety instrument family in a vehicle. The main purpose of seat belt is to minimize the injuries by preventing the occupant from impacting hard on interior parts of the vehicle and also the passenger from being thrown-out from the vehicle in case of rollover accidents. The standard three-point belt is mounted in the vehicle at three locations namely Anchor, D-ring and Buckle. The position of anchorages is very important to distribute the impact load evenly to the occupants. Very high load in any of these locations could cause breakage of the mountings and also concentrated loading on the occupant chest of pelvis. Current study mainly focuses on the seatbelt assembly performance improvement against UNECE-R16 sled test. The sled test was carried out first using 28g peak acceleration pulse and measurement of forces at shoulder and anchor position was measured using the load cell. FE (Finite Element) model of the complete seatbelt assembly was developed including Buckle, Retractor and Anchor plate. The simulation was…

ENHANCE STRENGTH, ACCURACY AND PRECISION OF THE 3D PRINTED ASSEMBLY AID GAUGES

General Motors Technical Center India-Ramesh Kavalur, Raghavendra Rao
  • Technical Paper
  • 2019-28-2568
Published 2019-11-21 by SAE International in United States
ENHANCE STRENGTH, ACCURACY AND PRECISION OF THE 3D PRINTED ASSEMBLY AID GAUGES Ramesh Kavalur1, Raghavendra Rao 1 1 Body in White, Manufacturing Engineering, General Motors Technical Centre India Pvt. Ltd, India, Keywords - Additive manufacturing, assembly aid gauges, 3D printer. Research Objective - Automotive manufacturing impressively implementing 3D printed jigs and fixtures. Traditional manufacturing of metal assembly aid gauges have limitations such as lead time and causes dent and rough marks on the outer panel of the body. On the other hand, 3D printed jigs and fixtures, demands more time (depends on complexity), have low level of precision and they offer lower strength. It is observed that this occurs because of the inefficient design and manufacturing without understanding the functionality and capability of the 3D printer. The primary objective of this study is to examine, design & develop 3D printed jigs and fixture to optimize the product, achieve required precision and functionality with improvement in the strength of the product. Methodology - In order to examine, detail examination of existing 3D printed part were studied.…

Robots Can Pick Up Any Object After Inspecting It

  • Magazine Article
  • TBMG-35425
Published 2019-11-01 by Tech Briefs Media Group in United States

For decades, robots in controlled environments like assembly lines have been able to pick up the same object over and over again. More recently, breakthroughs in computer vision have enabled robots to make basic distinctions between objects. Even then, though, the systems don’t truly understand objects’ shapes, so there’s little the robots can do after a quick pickup.
