Existing crash test dummies are commonly designed to work in a specific loading direction. Without validation of their responses in other directions, say with oblique forces, the use of such dummies to evaluate injury risks of occupants in complex loading conditions is questionable. This paper describes a conceptual dummy thorax structure which can function in pure frontal, pure lateral and oblique 60˚ loading directions by properly positioning spring-damper modules inside the thorax structure. The dynamic behavior of the thorax to these three different directions is simulated using lumped-mass spring damper models and by building a simplified two-dimensional finite element dummy chest model that couples all three directions. The results show that the dummy thorax model can work in multiple loading directions. The validated mathematical model is reliable, with potential to be used in thorax injury studies for multiple/complex crash loading conditions, including oblique impact.
