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 /.

The front and rear wings are essential in race cars in order to increase the down-force and enhance the stability of vehicle at high speed. The present work focuses on the computational modelling of NACA 4412 airfoil for front and rear wing of the racing vehicle and assesses its performance characteristics. The effect on wing characteristics in vicinity of ground and tire for varying angle of attack in moving ground frame has been studied. The computation has been carried out using high fidelity computational fluid dynamics model to solve the incompressible Navier-Stokes equations. The front wing has been split into two parts main wing and flap with chord length of 0.3 meters and 0.15 meters respectively. Similarly, the rear wing was modelled with the chord length 0.3meter and aspect ratio of 1.5. The pressure and velocity flow distribution over the body of the vehicle has been studied for varying angle of attack.

Light weighting is the Current trends in automotive to achieve better fuel economy which helps for meeting fuel economy standards & to offset the higher fuel prices. Thus there is a need to develop composite running board which is light weight & structurally sound enough to meet the performance. The present paper provides a composite running board assembly for an automobile. The running board assembly includes a board, an insert body and a plurality of brackets. Upon stepping of a passenger on the board, the board transfers load on the insert body which subsequently transfers the load to the plurality of brackets thus facilitating even distribution of the load on the automobile body. This paper also put lights on the use of improved TRIZ application - an approach to inventive problem solving for designing highly affordable & light weight running board.
