BACKGROUND Men tend to have more upper body mass and fat than women, a physical characteristic that may predispose them to severe motor vehicle crash (MVC) injuries, particularly in certain body regions. This study examined MVC-related regional body injury and its association with the presence of driver obesity using both real-world data and computer crash simulation. METHODS AND FINDINGS Rea...

Objective – Public concern has arisen about the reliability of front airbags because Fatality Analysis Reporting System (FARS) data indicate many nondeployed airbags in fatal frontal crashes. However, the accuracy of airbag deployment, the variable in question, is uncertain. This study aimed to provide more certain estimates of nondeployment incidence in fatal frontal crashes. Methods – Fatally...

Novel techniques for joining thermoplastic composites and aluminium alloys are critical underpinning the development of crashworthy lightweight multi-material automotive structures. Lap bonding interfaces represent a fundamental joint in typical This study investigates crashworthiness single-lap, adhesively bonded interlocked-hybrid composite-metal joints using low-velocity transverse impact te...

INTRODUCTION Longitudinal barriers, such as guardrails, are designed to prevent a vehicle that leaves the roadway from impacting a more dangerous object while minimizing the risk of injury to the vehicle occupants. Current full-scale test procedures for these devices do not consider the effect of occupant restraints such as seatbelts and airbags. The purpose of this study was to determine the e...

The safety of children in motor vehicle crashes is a major concern. Although Child Restraint Systems (CRS) are required by law for their protection, children are still exposed to the risk of injuries ranging from minor to fatal. The effect of restraint use is studied under different risk scenarios consisting of some possible contributors to injury risk: the restraint use, impact type, injury se...

this article aims at strategic vision to technology and suggests a strategic planning for this purpose. the main emphasis in this article is on strategic report compilation in the framework of strategic vision and covers issues such as identification of strategic planning dimensions and strategic vision levels, technology priority setting, environment monitoring, focus on costumer needs, method...

applying robust optimization to solve product mix problem in automotive industries in this article, applying robust optimization in product mix problem in automotive industries is presented. the problem includes determining both the quantity and the identification of each product to produce to maximize profit. at first, the deterministic model will be presented. then, robust model of product mi...

A finite element (FE) model of a 1998 Audi Model A8 has been developed for the crash analysis associated with the NHTSA NCAP program. The AUDI model A8 is an all aluminum four-door passenger vehicle; it is classified as a ‘large sedan’ car. The model developed is to be used to analyze frontal impact against a rigid barrier as specified in standard procedures associated with the assessment of pa...
