Determination of Impact Responses of ES-2re and SID-IIs – Part II: SID-IIs 2018-01-1448

The main purpose of this study was to determine the impact responses of the different body regions (shoulder, thorax, abdomen and pelvis/leg) of the ES-2re and SID-IIs dummies using rigid wall impacts under different initial test conditions. The experimental set-up consisted of a flat rigid wall with five instrumented load-wall plates aligned with dummy’s shoulder, thorax, abdomen, pelvis and knee impacting a stationary dummy seated on a rigid seat at a pre-determined velocity. The relative location and orientation of the load-wall plates was adjusted relative to the body regions of the ES-2re and SID-IIs dummies respectively. The load-wall forces and dummy responses were primarily evaluated by varying four different test parameters – effect of velocity (initial velocity vs. velocity-time pulse), effect of shoulder engagement (with and without shoulder load-wall plate), effect of initial arm position of the dummy (40 deg. vs. 90 deg.), and effect of oblique loading of thorax by rotating the thorax load-wall plate by 15 deg. Further, the transfer functions between these two dummies for similar impact conditions were derived. Results of this study were reported in three parts: Part I presented determination of impact responses of ES-2re dummy appeared in SAE Paper 18SS-0384; Part III deals with derivation of transfer functions between responses of ES-2re and SID-IIs dummies will be presented in SAE Paper 18SS-0386. This paper addresses Part II pertaining to determination of impact responses of SID-IIs dummy.
