Fundamentals of Threaded Fasteners

2019-12-18
Fastener experts believe that upwards of 95% of all fastener failures are the result of either the wrong fastener for the job or improper installation. Whether this shocking figure is accurate or not, it is irrefutable that threaded fasteners are poorly misunderstood by many in both the fastener and user communities. In October 1990 the USS Iwo Jima suffered a catastrophic steam valve accident minutes after leaving port following repairs to its steam plant. In one of the single most deadly events of Operation Desert Storm, ten of the eleven crewmen present in the engine compartment would lose their lives.

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.

LIGHT WEIGHTING OF ADDITIVE MANUFACTURED PARTS FOR AUTOMOTIVE PRODUCTION APPLICATIONS THROUGH TOPOLOGY OPTIMIZATION TECHNIQUES

2019-11-21
2019-28-2544
Rapidly enhancing engineering techniques to manufacture components in quick turnaround time have gained importance in recent time. Manufacturing strategies like Additive Manufacturing (AM) are a key enabler for achieving them. Unlike traditional manufacturing techniques such as injection molding, casting etc., AM unites advanced materials, machines, and software which will be critical for Industry 4.0. Successful application of AM involves a specific combination and understanding of these three key elements. In this paper the AM approach used is Fused Deposition Modelling (FDM). Since material costs contribute to 60% of the overall FDM costs, it becomes a necessity to optimize the material consumption of the produced parts. This paper reports case studies of 3D printed parts used in an Automobile plant’s production aids, which utilize computational methods(CAE), topology optimization and FDM constrains (build directions) to manufacture the part in the most optimal way.
