Shoulder joint design of the anthropometric dummy used for crash tests

Abstract

The article introduces a design of the shoulder joint of the anthropometric dummy intended for rear crash tests at low speed. The joint was used to build a mannequin representing a 50th percentile male. The construction ensures the strength of individual components of the joint without the need for frequent replacement of components and their calibration. The designed joint is connected to other elements of the dummy using overlay screw connections. The joint has variable characteristics of stiffness and elasticity, thanks to which it is possible to use this joint in dummies representing the remaining percentiles of the population. The range of movement of the joint was chosen to reflect the range of mobility of the adult’s man shoulder joint. The joint was compared to the shoulder joint used on the Hybrid III dummy representing a 50th percentile male.
