In the present paper, employing a complete model of a passenger car, contribution of various components and assemblies in the frontal crash energy absorption is determined. Thickness of components with more remarkable contribution is increased to improve the occupant safety. Furthermore, effects of substituting the metallic bumper with one fabricated from GMT materials on the frontal crash beha...

Thin-walled structures like crash boxes may be used as energy absorption members in automotive chassis. There have been many studies addressing the behaviors of energy absorption members on frontal crash. These researches have attempted to predict the energy absorption and maximum impact load in shell structures. The energy absorption and maximum impact load depend on many parameters including ...

The Event Data Recorders (EDRs), now being installed as standard equipment by several automakers, are increasingly being used as an independent measurement of crash severity, which avoids many of the difficulties of traditional crash reconstruction methods. Little has been published however about the accuracy of the data recorded by the current generation of EDRs in a real world collision. Prev...

Modern vehicle designs tested as part of US consumer information programs achieve high ratings for frontal crash protection. Research is needed to determine how these tests can be upgraded to further improve occupant protection in real-world frontal crashes. The present study is a detailed analysis of real-world cases with serious injuries resulting from frontal crashes of vehicles rated good f...

Consumer crash test programs provide comparative information on the crashworthiness of new vehicles which, in turn, should predict the performance of the same vehicles in real-world crashes. However, the detail and quality of available information from tests and real-world crashes differ widely, so identifying meaningful relationships between crash test results and real-world crashworthiness ca...

this study is to report characteristics of people killed in road traffic crashes and to describe major patterns of traffic crashes in china.descriptive and inferential statistical analyses were conducted. road traffic death national data, population denominator data and motor vehicles data of 2009 were obtained from the bureau of traffic management at ministry of public security and national bu...

To construct the lumped spring-mass model considering the occupants for the offset frontal crash, the SISAME software and the NHTSA test data were used. The data on 56 kph 40% offset frontal vehicle to deformable barrier crash test of a MY2007 Mazda 6 4-door sedan were obtained from NHTSA test database. The overall behaviors of B-pillar and engine of simulation models agreed very well with the ...
