Mahindra & Mahindra, Ltd.-Jayanthan Balasubramanian, Rahul Lalwani, Vinay Kumar
  • Technical Paper
  • 2019-28-2561
To be published on 2019-11-21 by SAE International in United States
TITLE: MITIGATION FOR EDGE CORROSION PROTECTION FOR AUTOMOTIVE BODIES. Keyword: Edge corrosion, Edge protection, Rust on edges, Corrosion mitigation. Objective: A major challenge to automotive industry is to protect the vehicle from corrosion in varying environment with respect to different service conditions. One of the main types of corrosion that affects aesthetic look is edge corrosion on sheet metal. Mostly edge is acting as starting point of corrosion due to unprotected metal exposed to environment. A special attention to be given to exposed edges to protect from rust formation. Methodology: To mitigate corrosion in visible area, various solution proposed in manufacturing process, material usage, sealer application, BIW design. Samples were prepared as per design of experiments with respect to manufacturing process condition and subjected for testing. Results: Proposed solutions were validated in manufacturing process line and reports are discussed. Improvements observed in controlled lab testing were furnished with observations and recommendations. Limitation of this study: On high volume passenger and commercial segment, corrosion mitigations are linked with high cost impact where high-end corrosion protection like…

Robot “Eye” Provides 360° Field of View

  • Magazine Article
  • TBMG-35159
Published 2019-09-01 by Tech Briefs Media Group in United States

The production of precision products depends on robot control systems knowing the location of the adhesive bonding head or welding head to the nearest millimeter at all times. This means the robot needs some sort of eye. Specialized sensors can perform this function, most of which operate on the principle of laser triangulation. A laser diode projects a line of red light onto the workpiece, from which the light is reflected at a specific angle before being detected by a camera. From the position of the light striking the camera chip, the position and distance of the sensor with respect to the workpiece within the coordinate system can be calculated.

Measuring Stickiness of Microscale Surfaces

  • Magazine Article
  • TBMG-35124
Published 2019-09-01 by Tech Briefs Media Group in United States

At the scale of bridges or buildings, the most important force that engineered structures need to deal with is gravity. But at the scale of microelectro-mechanical systems (MEMS) — devices like the tiny accelerometers used in smartphones — the relative importance of gravity decreases and adhesive forces become more important.

Stuck on structural adhesives

Automotive Engineering: September 2019

Bill Visnic, Lindsay Brooke
  • Magazine Article
  • 19AUTP09_02
Published 2019-09-01 by SAE International in United States

As the need for lighter materials and enhanced body performance intensifies, structural adhesives flourish as a materials-joining solution.

A funny thing happened on the way to the total-vehicle light-weighting that's now a common engineering dictate for nearly every new vehicle: structural adhesives-which entered low-volume automotive use in the 1980s-got pulled into the mainstream.

The Rodney Dangerfield of Automated-Driving Sensors

Autonomous Vehicle Engineering: July 2019

  • 19AVEP07_06
Published 2019-07-01 by SAE International in United States

Radar and lidar get all the attention, but Inertial Measurement Units are the backbone of sensor fusion. Suppliers are scrambling to make IMUs more accurate-and much less expensive.

The emerging era of highly-automated driving comes courtesy of much-vaunted sensor technology-spinning lasers, penetrating radar, sonar blips. But the sensor that gets the least respect in the technology stack could be the lynchpin for the mass roll-out of self-driving vehicles: the inertial measurement unit (IMU).
