Abstract
Numerical simulation techniques are commonly used to assess the crash performance of automobiles and guide their design during the development stage. Mathematical models of vehicle structures, restraint systems and dummies are developed and verified under different test conditions to ensure an effective usage during their application in the study of a crash situation.
This paper describes the development and validation of a finite element model of the US Department of Transportation (DOT) side impact dummy (SID). The geometry of the dummy parts is represented by shell and solid elements created from a digital scan of the dummy and the material properties are derived from quasi-static tests of each component. Springs and rigid bodies are added to represent the shock absorber and certain rigid parts such as the femur and ilium.
The model verification is carried out by subjecting the dummy to twenty four impact conditions and comparing the simulations to test results.
