Crashworthiness studies are in high demand for designing transportation systems. Energy absorption capability in vehicle collisions is an important parameter for the development of passive safety systems dealing with the protection of passengers and cargo departments in the event of an accident. Protective structures, which contribute significantly to the crashworthiness capability of automotiv...

This article develops an incremental learning algorithm based on quadratic inference function (QIF) to analyze streaming datasets with correlated outcomes such as longitudinal data and clustered data. We propose a renewable QIF (RenewQIF) method within paradigm of estimation inference, in which parameter estimates are recursively renewed current summary statistics historical data, but no use an...

during the design and development of truck cabins, the safety of the driver and the front seat passenger in an accident is an important task and should be considered. the cab must be designed in such a way that in an accident a sufficient survival space is guaranteed. the aim of this study is to investigate the behavior of iran khodro (ikco) 2624 truck subjected to a complex crash test accordin...

Abstract Demands for lightweighting and crashworthiness of the vehicle body have increased. For this purpose, advanced high strength steel to automobile was regarded as a solution with respect manufacturing cost impact energy absorption. However, increasing automotive sheet lead diversity problems caused by tool wear due higher forming load than that commonly used sheets. Hence, systematic expe...

PURPOSE : The purpose of this study is to establish whether motor vehicular crash (MVC) case fatality varies across different urbanization levels in the USA using a representative sample of crashes. METHODS : Odds ratios (ORs) and 95% confidence intervals (CIs) for the association between urbanization level [i.e., central city (CC), suburban (SU) and others (OT)] and mortality were estimated ...

In the roadside safety community, there has been debate over the influence of vehicle and barrier type on rollover rates in traffic barrier crashes. This study investigated rollover rates between sport utility vehicles (SUVs), pickup trucks, and cars in vehicle-traffic barrier crashes and has examined the effect of barrier type on rollover risk for concrete barrier and metal barrier impacts. Th...

Prior studies on racial and ethnic disparities in survival after motor vehicle crashes have examined only population-based death rates or have been restricted to hospitalized patients. In the current study, we examined 3 components of crash survival by race/ethnicity: survival overall, survival to reach a hospital, and survival among those hospitalized. Nine years of data (from 2000 through 200...

B-pillar and rocker are the key force transmission sub-systems of side impact battery electric vehicle (BEV), scholars have studied crashworthiness these body a lot. However, works insufficient on analysis benchmarking models, simulation experiment sub-systems, optimization sub-systems. To make up shortcomings, this work aims to design improve BEV. It presents systematic method The dynamic bend...
