Development of the MADYMO CRABI-6 Dummy Head Model for Side Impact Simulation

This paper describes the development of a validated MADYMO CRABI-6 dummy model for the purpose of simulating lateral impact to the CRABI-6 dummy. An investigation of the current CRABI-6 model revealed that the contact interaction properties of its head are significantly flawed. Without further development, such a model produces incorrect injury values and flawed dummy dynamics. Laboratory tests to characterise the lateral dummy head response were designed and conducted. Using mathematical methods, a MADYMO model was developed to simulate the laboratory tests and validated against laboratory results. Both injury prediction and timehistory responses were used as a basis for comparison. Good correlation between the computer model and laboratory tests was obtained, resulting in a model capable of predicting side impact injury responses for the CRABI-6 dummy.
