Device for determining relative movement and twisting angle of a dummy foot during an accident simulation, has optical system arranged for determination of relative movement of dummy foot

摘要

The device determines the relative movement and the twisting angle of a dummy foot opposite its ankle during an accident simulation, with all twisting angles being recorded. An optical system is arranged for the determination of the relative movement of a dummy foot (7), from a source of light (2), a screen (3), a spherical mirror (4), a ball joint (5) is arranged to simulate the human foot, a quadrant sensor exists with a lens (8) before-arranged from the quadrant sensor. The center of the ball joint (5) corresponds to the kinematic center (9) of the optical system.
