BlockChain - A disruptive technology in Automotive Industry

Automotive Software-Prabha Baragur Venkataram
  • Technical Paper
  • 2019-28-2436
To be published on 2019-11-21 by SAE International in United States
When i decided to buy a second hand car from a dealer to learn driving, i was sceptical of the mileage usage for which a particular price was charged. Though the well know dealer told me a about the car, its previous usage, the fact that there were no accidents, and so on, there was no reliable way to verify what the dealer was offering. In order to solve such issues, we are looking at a disruptive technique which will cause a complete paradigm shift - by using blockchain technique. This paper talks about the basics of the blockchain technology and its relevance in automotive industry. We also look at some real life scenarios, where this technology helps to build reliability as one of the implicit requirements. We will start looking at how the block chain will help to reliably select the right components in the assembly line. Also we look at different aspects of software architecture like security and how blockchain can provide solutions in this area. Also we will look at the Service…

To be published on 2019-11-21 by SAE International in United States
Research Objective The objective of the paper is to research what are the changes in experiences being brought about due to the advent of Electric Vehicles (EVs). EVs are silent, have less complex propulsion system, and have free space under the hood, amongst other things. Each change brings about both good and bad experiences across the spectrum of users. Some of the bad experiences can be safety incidents leading to death as well. Researching the areas that are harmful to end users, including pedestrians, will be our focus area. Methodology Our methodology will look at the changes at the vehicle architecture level which are inherent to the EV design. Research how are the experiences so far due to these changes. Are these just inconveniences or safety hazards? EVs have excellent NVH characteristics. A farmer may love a silent tractor, but a racing enthusiast may not like a relatively silent sports car. A silent armored vehicle may be what the army needs, but a silent car’s approach may be a last-minute surprise to an unsuspecting pedestrian,…

Generally brake pads are manufacturing by use of asbestos materials, these materials are chemically harmful and toxic, affects human health. The present investigation fabricates polypropylene composites with mixing constant volume [5 Vol.%] of alumina nano particles and different volume percentages [0%, 5%, 10% & 15%] of basalt fibre by hand layup compression technique. The wear characteristics of polypropylene matrix composites were tested by dry sliding condition using pin on disc apparatus configuration with hardened steel counter-face at elevated temperature. The load was applied 30N to 70N with the interval of 20N and varying of sliding speed 300 rpm to 900rpm with the interval of 300rpm for the time period of 0-180 sec. The wear rate was decreases with addition of alumina nano particle and also increases the frictional force for the effect of basalt fibre content present in the composites. The co-efficient of friction was increases from 0.1 to 0.66 under normal loading condition.

Currently automotive industry is facing bi-fold challenge of reduction in Greenhouse gases emissions as well as low operating cost. On one hand Emission regulations are getting more and more stringent on other hand there is major focus no customer value proposition. Engine blow by gases are one of the source of Greenhouse gases emission from engine. Blow by gases not only consist of unburn hydrocarbons but also carry large amount of oil. If oil is not separated from these gases, it will led to major oil consumption and hence increase total operating cost of Vehicle. In this paper, effort has been taken to develop a low cost closed crank case ventilation with oil mist separation system on diesel engine. For cost effective solution, two different design and configuration of oil mist separation system has been developed Further, engine with two different above said configuration has been tested for blow by gasses and oil consumption measurement on Engine test bed and vehicle to understand the behavior in real environment. Further results has been compare for both…

Development and Investigation of Jute/Linen Fibre Reinforced Polymer Composite

BSA Crescent Institute of Science & Technology-Arvinda Pandian, Siddhi Jailani
Published 2019-10-11 by SAE International in United States
In recent automotive era, natural fibre reinforced with thermoset polymer composites have been incorporated by automotive industries especially for interiors, car body panels, dashboards, headliners etc. Natural fibres offer many affirmative qualities such as less weight and cost, especially in reduction of carbon di-oxide which is a major threat to the planet from the automotive sectors. The current work deals with the study of the potential usage of mineral powder (industrial by-product) in polymer. In this paper, hybrid composites with natural fabrics reinforcements and mineral powder as filler to matrix material are developed. The mineral powder used as filler is silica fumes which is a by-product of industries. The hand lay-up methodology is employed to fabricate the composite. The composites with and without mineral filler material are developed. The mechanical properties of the composites are assessed. The mechanical properties of composites with and without mineral filler are compared and their result shows that with addition of filler material, the mechanical properties of the composites are affected. Results disclose that loading of silica fumes increases the…

Programmable Soft Actuators for Soft Robotics

  • Magazine Article
  • TBMG-35348
Published 2019-10-01 by Tech Briefs Media Group in United States

Researchers have developed highly programmable actuators that, similar to the human hand, combine soft and hard materials to perform complex movements. These materials have great potential for soft robots that can safely and effectively interact with humans and other delicate objects.
