Metamodel-based robust design methods are commonly used to mitigate the influence of parametric uncertainty associated in sheet gauges and material properties in crashworthiness-based vehicle lightweight design. Since the crash performances are highly nonlinear and high-dimensional responses, the prediction error of metamodels inevitably introduces the so-called metamodeling uncertainty in robu...

OBJECTIVE To determine the number and characteristics of motor vehicle crash deaths related to police pursuits in the United States. METHODS Analysis of the Fatality Analysis Reporting System and the Crashworthiness Data System of the National Highway Traffic Safety Administration for the years 1994-2002. RESULTS There were 2654 fatal crashes involving 3965 vehicles and 3146 fatalities duri...

parametric design optimization of an automotive body crashworthiness improvement is presented. the thicknesses of parts are employed as design variables for optimization whose objective is to increase the maximum deceleration value of the vehicle center of gravity during an impact. using the taguchi method, this study analyzes the optimum conditions for design objectives and the impact factors ...

Small overlap frontal crashes occur when vehicles are loaded outboard of their longitudinal structural members. Studies from the 1990s as well as current research have found that these crashes continue to account for a significant percentage of all serious frontal crashes. The National Automotive Sampling System/Crashworthiness Data System database was used to study the characteristics of these...

Abstract As a class of promising cost-effective lightweight structures, metal-composite hybrids have rapidly emerged in automotive industry largely attributable to their outstanding multifunctional and crashworthy characteristics. The aim this study is investigate the potentiality cylinders for crash energy absorption applications. In context, crashworthiness performance, deformation history ju...

Stainless is now a candidate for structural applications. Offering weight savings, enhanced “crashworthiness” and corrosion resistance, it can also be recycled. The material blends tough mechanical and fire-resistant properties with excellent manufacturability. Under impact, high-strength stainless offers excellent energy absorption in relation to strain rate. It is ideal for the revolutionary ...
