In order to find an efrective measure to improve protection in side collisions, sled tests were conducted to clarify how parameters, such as the collision velocity of the body side with the dummy, the body side intrusion into the compartment, side deformation, collision angle and side padding materials, influence the dummy injury in side collisions. Side impact dummies developed by HSRI were used in this study, we examined its characteristics by dummy drop tests and sled tests.
Of the variables in side collisions, the collision velocity of the dummy is found to have the greatest effect on the dummy injury value. In addition, when the side impact dummy undergoes a lateral impact on the chest, the dummy shows characteristics apparently different from those of the Hybrid-II dummy due to the modification of the chest. However, there are still some problems to be solved in the future including cases where the dummy chest receives an oblique impact.
