NEXT GENERATION POWER DISTRIBUTION UNIT IN WIRING HARNESS

Mahindra & Mahindra, Ltd.-Boobala Krishnan D, Himanshi Dua, T Vijayan, Apurbo Kirty
  • Technical Paper
  • 2019-28-2571
To be published on 2019-11-21 by SAE International in United States
Keywords – Miniaturization, Low Profile (LP) Relays, Low Profile (LP) Fuses, Fuse box, Wiring Harness Research and/or Engineering Questions/Objective With the exponential advancement in technological features of automobile’s EE architecture, designing of power distribution unit becomes complex and challenging. Due to the increase in the number of features, the overall weight of power distribution unit increases and thereby affecting the overall system cost and fuel economy. The scope of this document is to scale down the weight and space of the power distribution unit without compromising with the current performance. Methodology Miniaturization involves replacing the mini fuses and J-case fuses with LP mini and LP J-case fuses respectively. The transition doesn’t involve any tooling modification and hence saves the tooling cost. Furthermore, to address stringent weight and space targets, LP mini fuses and LP J-case fuses were further replaced with micro-2 fuse and M-case fuse respectively. Similarly, micro relay and mini relay were replaced with Ultra micro and High current micro relay respectively. Results We took MPV segment vehicle for our initial testing and validation…

Development of low cost life saving system for Automotive vehicles during Road Accidents.

Tata Technologies, Ltd.-Sachin Madhukarrao Pajgade, Aashish Bhargava
  • Technical Paper
  • 2019-28-2460
To be published on 2019-11-21 by SAE International in United States
According to research study 45% of death cause due to not getting help on time to the injured person. Research has proven that if injured person is not found any option of help then they also loose the power to fight such critical situation due to psychological effect. When vehicle met accident, people are not getting on time support, this delay is the major cause of death in developing nations. Presently there is no any robust system available in market for passenger & commercial vehicles which helps to provide on time help to the injured persons & saves human life. In current situation low cost life saving device is need of our society. This paper deals with the design & development of the low cost-life saving device. This paper also comprises the scenario when any vehicle meet an accidents within certain speed limit then how the intelligent life saving device will work & save the life's. Further it explains the type of life saving device design, logical programming and system packaging. The system has been…

Heat Shield Insulation for Thermal Challenges in Automotive Exhaust System

Sharda Motor Industries, Ltd.-Sivanandi Rajadurai, Ananth S
  • Technical Paper
  • 2019-28-2539
To be published on 2019-11-21 by SAE International in United States
While advanced automotive system assemblies contribute greater value to automobile safety, reliability, emission/noise performance and comfort, they are also generating higher temperatures that can reduce the functionality and reliability of the system over time. Thermal management and proper insulation are extremely important and highly demanding for the functioning of BSVI and RDE vehicles. Frugal engineering is mandatory to develop heat shield in the exhaust system with minimum heat loss. Heat shield design parameters such as insulation material type, insulation material composition, insulation thickness, insulation density, air gap thickness and outer layer material are studied for their influences on skin temperature using mathematical calculation, CFD simulation and measurement. Simulation results are comparable to that of the test results within 10% deviation. The performance index is calculated using the temperature gradient between the pipe surface and the external skin temperature. The performance index increases with material insulation thickness and insulation material density. Increase in insulation thickness from 6 mm to 19 mm reduces the skin temperature from 44% to 77%. The specialty insulation material provides a high…

Guide to Package Integrity & Validation Testing under ISO 11607 and MDR

  • Magazine Article
  • TBMG-35085
Published 2019-09-01 by Tech Briefs Media Group in United States

Updates to ISO 11607, Parts 1 and 2, have left many medical device manufacturers wondering about the future of their packaging designs. These changes come at a stressful time for OEMs, as Europe is also in the process of replacing the current Medical Device Directive (MDD) with the Medical Device Regulation (MDR) in 2020. The interplay between ISO 11607 and MDR is complex, and it’s difficult to predict regulators’ plans for enforcement.
