One of the most important safety critical components on cars, trucks, and aircraft is the pneumatic tire. Vehicle tires primarily control stopping distances on wet and dry roads or runways and strongly influence over-steer/under-steer behavior in handling maneuvers of cars and trucks. The inflated tire-wheel assembly also acts as a pressure vessel that releases a large amount of energy when catastrophically deflated. The tire can also serve as a fulcrum, both directly and indirectly, in contributing to vehicle rollover. This seminar covers these facets of tire safety phenomena.

The tire is generally characterized on the basis of forces and moments being generated at the contact patch, which generally describes the friction potential of the tire in both longitudinal and lateral directions at different load conditions. The field conditions under which the tires perform is diverse which results in varied performance for the same product. To understand this there is a need to understand range of friction values the tire undergoes in different conditions which cannot be replicated in indoor test-rigs. The longitudinal potential of tire is the important factor in determining the acceleration and braking behaviour, so braking test was performed to measure the longitudinal slip and forces. A joint project has been undertaken between Apollo Tyres and ARAI, where both have used their technical expertise to work on tire characterization out of road test.

Road roughness induces dynamic loads on vehicles, which cause fatigue damage as a result. Design of vehicle for durability is one of the key steps during vehicle development process. Vehicle durability is verified on test tracks, on test rigs, or, increasingly, by computer simulations. Does the test represent real-life vehicle usage? How many times should a vehicle travel over the test tracks to verify the durability? For doing this kind of analysis, it is always required to measure the vehicle response parameters such as wheel forces, axle and chassis acceleration etc. These measurement based approaches have high cost and are time consuming. As these are vehicle dependent parameters, exercises need to be repeated on each type/class of vehicle . Hence it is needed to accelerate this process using parameter which is vehicle independent i.e road profiles. This paper discuss about the methodology, process developed at ARAI for generation of 3d road profile database (in .CRG /.

KEYWORDS – Asphalt concrete mixture, Wet Handling, Coefficient of adherence, aging procedure, Pavement durability, Binder, Additives. ABSTRACT – Asphalt specifications for a Wet Handling tracks are very stringent in the sense of Coefficient of adherence and homogeneity of this coefficient along the time. Currently, asphalt mixture pavements used in wet conditions have a very limited useful life and this keeps degrading following different patterns according to the different asphalt mixtures used. This is because of many reasons but mainly as a consequence of supporting big strains and the extreme conditions during its whole useful life submitted for having the asphalt completely deep in water for most of its live time as well as climatic weather conditions. Moreover, Wet Handling pavements should provide very specific and stable adherence values for vehicle testing during the asphalt aging evolution.

BIW (Body-in White) is a type of vehicle structure formed by spot welding of different sheet metal components. The BIW structure should be designed to support the maximum load potential under various performance conditions. Thus the structure should have good strength as well as stiffness. Torsion Stiffness of BIW is the amount of torque required to cause a unit degree of twist. It is often considered as a benchmark of its structural competence due to its effect on various parameters like ride, handling, lateral load distribution and NVH performance of vehicle. This paper presents a case study in which physical testing was carried out for obtaining the global torsional stiffness, simulation was carried out replicating the physical test conditions. The simulation result was found to be 94% correlated with the test results.

In commercial Vehicles, the purpose of suspension is not only passenger's ride comfort and load carrying, but also accompanying vehicle's handling. Road profile, vehicle design and driver input contribute a lot to the vehicle behavior specially when vehicle is turning, braking and bouncing. One of the vehicle behaviors is brake steering where vehicle itself steers on braking and can be a major cause for life threatening accidents on highways and express ways. In this paper, leaf spring wind-up and vehicle behavior on braking is studied analytically, observed experimentally and characteristics were analyzed. Also, the effect of the same on design parameters is studied and thereby recommendation is derived. In analytical part of paper, various spring's wind off parameters such as Dynamic load on spring, perpendicular distance of projected twisted surface, Angle of spring wind-up, and Induced stress during braking are calculated.

Blade Electric Vehicles (BEVs) have received more and more attention from both consumers and automotive enterprises because of their being safer, more energy-saving and environmental friendly. However, BEVs’ development and promotion have had the major challenges such as high use cost, short driving distance and safety issues since they came up initially. To overcome those difficulties, the technologies for driving cell,motor and controller have recently achieved some progresses. Besides, vehicle lightweight technology was also a valid solution for those issues above and it could be much simpler and more effective. According to previous research, in terms of reducing the body weight, the application of new materials (such as light metals and composite materials) was a well-known method whereas their high cost caused the overall increasing of BEVs’ price.

Dynamic Analysis of Outside rear view mirror of a car S. W. Thor1, S. P. Chippa1*, A. S. Majage2 1Department of Mechanical Engineering, Vishwakarma Institute of Technology, Pune 2Finite Four Technologies, Pune *Correspondence author : chippashriniwas@gmail.com Abstract:- An Automobile rear view mirror is attached at the side of the vehicle which is used to provide clear vision outside the vehicle. In the running condition of vehicle, various vibrations occur and are transferred to the mirror which may disturb driver's rear view. Since this issue is related to safety consideration, it becomes essential to minimize the vibration of mirror. Vibration analysis is very much important for the successful design and development of new parts in automobile. In present work, Vibration analysis of existing design of outside rear view mirror is investigated through numerical model using FEM. Furthermore, these results are verified through experimental work.
