A new appraisal of the thermomechanical behaviour of a hybrid composite brake disc in a formula vehicle Research Objective This paper presents a hybrid composite brake disc with reduced Un Sprung Weight clearing thermal and structural analysis in a formula vehicle.Main purpose of this study is to analyse thermomechanical behaviour of composite brake disc for a formula vehicle under severe braking conditions. Methodology In the disk brake system, the disc is a major part of a device used for slowing or stopping the rotation of a wheel. Repetitive braking of the vehicle leads to heat generation during each braking condition. Based on the practical understanding the brake disc was remodelled with unique slotting patterns and grooves, using the selected aluminium alloy of (AA8081) with reinforcement particle of Silicon carbide (SiC) and Graphite (Gr) as a hybrid composite material for this proposed work.

Vehicle weight reduction becomes important at the view point of fuel efficiency improvement and CO2 reduction in India also as well as developed countries. With this background, High tensile and Super high tensile steel application has become increasing. Similary, weight reduction of big plastic parts like bumper face is one of the most important items, so Honda has developed Thin-wall and light weight bumper face. In the development of light weight bumper, rigidity, impact strength and flowability which are main requirement are cotradictory property. It is necessary to develop new material to achieve this technical concern. Moreover, we verified part shape and thickness optimization to achieve part requirement. Established high property material and part manufacturing technology were applied for current CITY firstly, and it has been expanded to other models sequentially to contribute weight reduction for Honda vehicles.

A novel approach on range prediction of a hydrogen fuel cell electric truck C.Venkatesh - Manager - Product Development, Sustainable Mobility & Advanced Technologies Abstract: A novel approach on range prediction of a hydrogen fuel cell electric vehicle Abstract: Today's growing commercial vehicle population creates a demand for fossil fuel surplus requirement and develops highly polluted urban cities in the world. Hence addressing both factors are very much essential. Battery electric vehicles are with limited vehicle range and higher charging time. So it is not suitable for the long-haul application. Hence the hydrogen fuel cell based electric vehicles are the future of the commercial electric vehicle to achieve long range, zero emission and alternate for reducing fossil fuels requirement. The hydrogen fuel-cell electric vehicle range, it means the total distance covered by the vehicle in a single filling of hydrogen into the onboard cylinders.

A DIGITALIZED VALIDATION APPROACH FOR REAL TIME AND REMOTE MONITORING OF AN OFF-HIGHWAY VEHICLE PERFORMANCE V.Jagannathan 1.a* , B.Jaiganesh 2.b & S.Sudarsanam 3.c Mahindra & Mahindra Limited, Mahindra Research Valley, Mahindra World City, Anjur PO, TN, India Corresponding author Email- V.JAGANNATHAN@mahindra.com Validation of agricultural tractors is necessary to ensure that these machines perform to their expected potential and are aptly matched with implements. Testing these machineries in real-time while performing activities in the field allows a bigger picture to be seen; the performance data incorporates the effects of many external factors (Soil, Climate etc.). Tractor Performance data apprehending is the vital part of validation. Data acquisition of key performance parameters during field validation in different application/different countries is of utmost importance.

Paper Title - Wiring Harness Optimization towards Wireless vehicle Research and/or Engineering Questions/Objective (maximum 100 words)  In current scenario, wiring harness plays a vital role in inter-connecting electrical & electronic components fitted all across the vehicle.  As per cable standard, DIN 72551 or ISO 6722, copper conductors being used in stranded wires against cable cross-section & corresponding weight.  While going complete wire-less requires each component to have its own battery, ground, transmitter & receiver which indeed is a very costly affair to be employed in vehicle as huge development cost is required.  Here I'm suggesting an innovative method to make a vehicle apparently Wire-Less by creating local clusters connected to each other via conventional wiring harness & wire-less module.  Such method will apparently give a look of Wire-less vehicle itself & better advantages in terms of installation, service, troubleshooting, uptime & customer delight.  Moreover, direct benefits of Cost, Weight, FE will also be achieved.

In sheet metal painting for various applications like Tractor, Automobile, most attractive coating is metallic paints and it is widely applied using 3 coats 2 bake or 3 coat 1 bake technology. Both options, results in high energy consumption, higher production throughput time & lower productivity in manufacturing process. During various brainstorming & sustainable initiatives, paint application process was identified for alternative thinking to reduce burden on environment & save energy. Various other industry benchmarking & field performance requirement studies helped us identify the critical to quality parameters. We worked jointly with supplier to develop mono-coat system without compromising the performance & aesthetical properties. This results in achieving better productivity, elimination of two paint layers, substantial reduction in volatile organic content, elimination of one baking cycle and energy saving.

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.

2019-28-2411
A high impetus from Government on road infrastructure development, is giving a fillip to passenger CV space. This has resulted in making the passenger CV segment lucrative enough, thereby pulling in many operators in the business. The quality of road has immensely improved over a decade, as a result of which the average speed and hence the quantum of distance covered by passenger buses has increased significantly. People are preferring to travel in buses over trains, owing to at par ticket cost, high availability, reduced travel time and also improved level of comfort. Aligned to the market need and the trend, OEM's are offering buses with capable powertrains to cater the need of speed, reduced trip time as well as a lot of attention is also being paid to tune in the comfort level for long hauls. A big chunk of passenger travel is catered by the bus operators especially during major festivals in India.
