Abstract
Mathematical modelling is widely used for crash-safety research and design. However, most occupant models used in crash simulations are based on crash dummies and thereby inherit their apparent limitations. This paper describes a mathematical model of the real human body for impact loading. A combination of modelling techniques is applied using rigid bodies for most body segments, but describing the thorax as a flexible structure. The skin is described using an arbitrary surface consisting of triangular facets to simulate contact with structures like seats, belts and airbags. The model allows simulation of global injury criteria like chest deflection, acceleration, and neck loads. For a more detailed analysis, submodels can easily be integrated into the current whole body model. As an example a detailed neck model including muscles with reflex activation has been included, and results are compared to those of the standard neck model.
