Crash Analysis on Automobile Bumpers

CARE: An Automobile Crash Data Analysis Tool

T he University of Alabama, with National Highway Transportation Safety Administration funding for traffic accident problem identification and evaluation, has developed the Critical Analysis Reporting Environment software system to analyze automobile crash data. CARE’s developers designed it for use by transportation safety engineers and policymakers, rather than trained statisticians. To date,...

Analysis of Automobile Crash Responses Using Wavelets

Seat cushions for high-performance aircraft are typically selected for their ability to meet stringent specifications. One of the major criteria is the safety performance during an ejection. To address the design goals of cushion and material selection, a computational modeling method was developed that accounts for component and subsystem testing, component and subsystem modeling, validation c...

Effect of electronic stability control on automobile crash risk.

Per vehicle crash involvement rates were compared for otherwise identical vehicle models with and without electronic stability control (ESC) systems. ESC was found to affect single-vehicle crashes to a greater extent than multiple-vehicle crashes, and crashes with fatal injuries to a greater extent than less severe crashes. Based on all police-reported crashes in 7 states over 2 years, ESC redu...

Experiences during development of a dynamic crash response automobile model

A finite element automobile model for use in crash safety studies was developed through reverse engineering. The model was designed for calculating the response of the automobile structure during full frontal, offset frontal, or side impacts. The reverse engineering process involves the digitization of component surfaces as the vehicle is dismantled, the meshing and reassembly of these componen...
