Systems Engineering for Prognostics and Health Management (PHM) Systems

2020-03-16
Most complex systems are moving toward a “smart” solution, with automated methods for identifying and diagnosing problems. This course will explore how efficient systems can be designed in an effective manner to ensure that they meet performance requirements. Because predictive maintenance is important to the aerospace industry, this course will address systems engineering (SE) and review prognostic health management (PHM) and explain how you can utilize them to obtain a better system. Additionally, it will address requirements management; model-based design; and verification and validation

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.

Development of low cost closed crankcase ventilation with oil mist separation system on light duty diesel engine.

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.

FOUR WAY ADJUSTABLE HEAD RESTRAINT SYSTEM

2019-11-21
2019-28-2528
To reduce the incidence of whiplash-associated disorders caused by rear impacts, head restraints should be closer to the head which decreases the amount of relative motion and it is believed to reduce the risk of soft tissue neck injury. Drivers are raising complaints that the head restraint causes discomfort by interfering with their preferred head position, forcing them to select a more reclined seat back angle [1]. This paper is about the importance of head restraint system and how it can be improved by adjusting the angle between the head restraint and passenger`s head. It is essential to carry out research on head restraint that can be adjusted in forward and backward direction letting the cost of seats remain in budget.

THE NEED OF PERSONALIZATION AND OPPORTUNITIES IN AUTONOMOUS VEHICELS AND SHARED MOBILITY

2019-11-21
2019-28-2520
Shared mobility and Autonomous shared mobility take major share in Mobility 4.0. Personalization in a shared mobility will play a significant role in customer engagement in Autonomous world. In case of personal vehicle each customer will have their own personal settings in their own vehicle; in case of Autonomous shared mobility or shared mobility, we can satisfy individual customer need only by personalizing the vehicle for each individual user needs. This will give a cognitive feel of personal vehicle in a shared environment. We need technologies in improving vehicle interior and exterior systems and design to address personalization. We will be discussing on feasible opportunities of personalization and with illustrations in Vehicle Interior Cabin Space, Seat comfort, Compartments, Vehicle interior & Exterior Access / Controls.

Changes in user experiences of electric vehicles

2019-11-21
2019-28-2489
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.

Title Development of a Graphical User Interface (GUI) Based Tool for Vehicle Dynamics Evaluation Authors Mr. Shubham Kedia, Dr. Divyanshu Joshi, Dr. Muthiah Saravanan Mahindra Research Valley, Mahindra & Mahindra, Chennai Objective Objective metrics for evaluation of major vehicle dynamics performance attributes i.e. ride, handling and steering are required to compare, validate and optimize dynamic behavior of vehicles. Some of these objective metrics are recommended and defined by ISO and SAE, which involve data processing, statistical analysis and complex mathematical operations on acquired data, through simulations or experimental testing. Due to the complexity of operations and volume of data, evaluation is often time consuming and tedious. Process automation using existing tools such as MS Excel, nCode, Siemens LMS, etc. includes several limitations and challenges, which make it cumbersome to implement.

New CEC Gasoline Direct Injection Fuels Test – Comparison of Deposits and Spray Performance from New and Used injectors.

2019-11-21

The use of deposit control additives in European market gasoline is well documented for maintaining high levels of engine cleanliness and subsequent sustained fuel and emissions performance. Co-ordinating European Council (CEC) industry fuels tests have played a crucial role in helping to drive market relevant, effective and low-cost deposit control additives into European market fuels. Until now, there has not been a Gasoline Direct Injection engine test available to fuel marketers in any market globally. However, a new CEC engine test is currently being developed to address that gap. Based on an in-house VW injector coking test, it shows promise for becoming a useful tool with which to develop and measure the performance of deposit control additives. A key requirement of industry tests should be to replicate issues seen in consumer vehicles, thereby providing a platform for relevant solutions.
