Abstract Expanding and improving road network in India has been a catalyst for increased use of road transport in both passenger and goods sector. With improved road quality, bigger commercials vehicles have entered the market. These provide a larger cabin area and better amenities in the truck driver cabin. One of the most welcome features is berths for lying down and sleeping. In most designs though, only the functionality of the berth has been taken into consideration. Safety of the occupants of the berths in the event of panic braking or collision of the vehicle, has not been given adequate consideration. In this work, design of such berths from occupant safety point of view has been assessed. Kinematics of occupants, sleeping in different typical postures, during frontal impact, has been simulated and resulting critical injury levels have been estimated. Based on this information, different arrangements of belts in “screen” type configuration were developed.

Abstract Crush box in an automotive passenger car has become an integral part of structural design performing various functions like optimizing energy absorption in high speed impacts, replaceable part during low speed impacts etc. Design of crush box for high speed impacts is very important as it is the first major energy absorbing component in the load path and its deformation significantly affects the overall vehicle crash behavior. The present paper explains development of a hydro-formed crush box in the front end of a sports utility vehicle. Hydro-formed components have residual plastic strains and non - uniform thickness variation throughout their length which is difficult to measure from a physical test coupon. It is critical to add hydro-forming effects onto crash FE models as it significantly affects the deformation under high speed impact. But detailed forming simulations need mature design and material data which is not available during early phases of product development.

Pedestrians and cyclists are the most unprotected road users and their injury risk in case of accidents is significantly higher than for other road users. Though the level of safety for pedestrians, as established through Euro NCAP and others, has significantly increased over the last years, currently still more than 20% of road fatalities correspond to pedestrians. The test procedures and assessment methods for pedestrian safety show potential for further improvement and thus should be adjusted accordingly. The understanding of the influence and sensitivity between important variables describing a pedestrian crash is key for the development of more efficient and reliable safety systems. This paper reflects the related work carried out within the AsPeCSS project.

Abstract Recent trends in vehicle occupant protection have led to renewed interest in the perception of Roominess such as headroom, shoulder room and foot room etc. Occupants head room in vehicles is currently measured using tools, procedures and definitions described in SAE J1052 and J1100. “Head Position Contours” defined in SAE J1052 are useful in establishing accommodation requirements for head space [1]. With respect to the Indian Anthropometry database, the head position contour as per SAE J1052 will not be appropriate with Indian population. With this objective in mind a head movement envelope is generated using the software - RAMSIS Digital manikin. RAMSIS is widely used by Automobile Manufacturers for Digital Human Modeling. The head movement envelope is a collation of different movements of head during driving condition.

Abstract Robust and reliable FE-model spotweld characterization has been a challenge since spotweld technology was incorporated extensively into the automotive industry. The innovation required leads to constant enhancement of product performance; reduced time-tomarket, cost and weight. The need for quality requires robust development tools, consistency of design decisions, andrepeatability of the development process. Proper spotweld characterization has a clear impact on the above-mentioned needs and carmakers invest in efforts to increase the efficiency of the development process. Furthermore, the continuoususage of new steel grades increases the complexity of the topic. This paper presents an in-depth spotweld study that involves three different spotweld specimens: KSII; lap shear and peeling, for automotive steel grades and usual part thicknesses for each steel grade.

This SAE Recommended Practice establishes a uniform laboratory test method to evaluate the strength characteristics of roof systems. The test procedure is intended to provide reliable and repeatable results and to permit numerical comparisons. A test is conducted in which the vehicle roof system is loaded under controlled laboratory conditions. Structural strength measurements are obtained under load application angles chosen to concentrate forces on the forward portions of the roof panel and roof supporting structure.

Fixed rigid barrier collisions can represent severe automotive impacts. Deceleration conditions during fixed rigid barrier collisions are more readily reproducible than those occurring during impacts with yielding barriers. Barrier collision tests are conducted on automotive vehicles to obtain information of value in reducing occupant injuries and in evaluating structural integrity. The purpose of this SAE Recommended Practice is to establish sufficient standardization of barrier collision methods so that results of similar tests conducted at different facilities can be compared. The barrier device may be of almost any configuration, such as flat, round, offset, etc.

Collision tests are conducted on automotive vehicles to obtain information of value in evaluation of structural integrity and in reducing the risk of occupant injuries. The deformation resulting from a moving rigid barrier impact is more severe at a given speed than that produced by using an actual vehicle, but is more readily reproducible than that occurring during vehicle to vehicle impacts. The purpose of this SAE Recommended Practice is to establish sufficient standardization of such moving barriers and moving barrier collision methods so that results of tests conducted at different facilities may be compared.
