Abstract

A new “3D-MUSTERDS-Three Dimensional MultiPoint Sternum Displacement Sensing System” has been developed, in order to measure chest deflections of anthropomorphic dummy to be used in vehicle collision tests. The 3D-MUSTERDS consists of an optical position sensing system (which consists of light emitting diodes (LEDs) installed on the sternum and position sensing detector (PSD) cameras installed on the thoracic spine) to be placed in the rib cage, and an external system to calculate and control the coordinates. This new system is characterized by the ease in application to chest of Hybrid m dummy. It is also verified that its frequency response and the impact resistance are excellent, with sufficient capabilities as a practical system for the measurement of the sternum (chest) deflections in normal collision tests. This paper describes the outline of the system and some examples of its applications.
