Design Optimization of Hood System for Pedestrian Headform Protection

Hood is the closure provided in the frontal portion of the vehicle for covering the engine room. Any component disposed in the frontal portion of the vehicle becomes important because of aesthetic as well as regulatory requirements. Introduction of new regulations like pedestrian protection brings new challenges for the original equipment manufacturers and the governing authorities. Introduction of Pedestrian Protection regulation, a recent development in the automotive industry, has thrown several questions in front of original equipment manufacturers. This work explains the procedure to address such question and the learning associated with it.

Energy Dissipation Test: Effect of After-market Interior Fitments on Deceleration Values and Sharp Edges in Passenger Cars

Energy dissipation testing of vehicle's interior fitments is done at various defined locations as per the regulation ECE R21. Interior fitting impact tests became mandatory in April 2006 for models manufactured from April 2006 and April 2007 for models being manufactured before April 2006 in India. With the implementation of stringent safety regulations in India, it is mandatory that every manufacturer tests and certifies their product to comply with the automotive safety standards. Automotive industry has a challenging task of designing and evaluating the components that play a vital role in the event of an unfortunate accident. In this context, a number of tests on safety belt anchorages, seat anchorages and interior fittings such as instrument panel, steering wheel etc., are conducted.

High Speed Image Analysis: A multi parametric study affecting measurements in controlled impact tests

The field of Passive Safety is of primary focus for the automobile manufacturers. Number of changes has been incorporated in today’s passenger car, which not only protects its occupants but also other road users. This revolutionary change in technology calls for new development in evaluation procedures. Crash testing of vehicles is one such massive field of research. The nature and cost of these tests increases the need for better measurement techniques. High speed cameras are often used in the crash tests and image processing is done to study the deformation characteristics, dummy kinematics and steering wheel displacements. This paper discusses the effect of key factors like Camera positioning and 2D Calibration on the analysis of high speed images. The paper also discusses the experimental evaluation carried out to validate the same.
