LSTC / NCAC Dummy Model Development

This paper presents the modeling and validation status of the most commonly used crash test dummies in the regulatory and consumer crash test programs, the Hybrid III family of crash test dummies. Systematic modeling and validation procedures are established and adopted to ensure the accuracy, efficiency, robustness, and ease of use of the models. The procedures are based on the premise that the model must be based on the fundamentals of mechanics, focusing directly on component geometry and material mechanical properties. The dummy models are created and validated at the component level. The models are then integrated and re-evaluated at the system level. The paper presents the component and system level validation results of the HIII 50th and 5th percentile dummy models.
