WorldSID 50th percentile male is the latest state-of-the-art Side Impact Dummy that has been developed in order to enhance its similarity to human body performance in a side impact crash test scenario. Recently, the dummy manufacturer has released a new version of the Shoulder Clevis and Arm for WorldSID. This new shoulder joint improves several known problems from the previous design (especially arm positioning difficulties and excessive ease to move due to suit tension). However, the remarkable differences in the design may also lead to different arm and shoulder kinematics.

Several OEMs have performed crash and sled tests at IDIADA using this new WorldSID shoulder design. The results from these tests have led to believe that there could be a potential difference in the achieved results depending on the tested shoulder and arm. Because of this IDIADA has an ongoing research project that aims to check the behavior of these parts through back-to-back testing.

This paper includes the results found from several Pendulum tests that were performed at IDIADA using one dummy but two different shoulder clevis and arms. Some differences have been found when evaluating the reproducibility of these results. However, the authors are aware that these results may be due to the test mode that has been used and because of this;​ further testing will be done (including both Static Deployment Testing and Side Sled testing).
