On the 20th December 2018 DENATRAN (Departamento Nacional de Trânsito) published a new resolution that establishes future vehicle performance requirements in pole side Impacts in Brazil (Resolution 751/18). This new resolution gives the option to comply with Annex II (equivalent to UN R.135) or Annex III (equivalent to FMVSS 214). Although this will be applicable to new vehicle registrations from the 1st January 2030, it is possible to anticipate its total or partial adoption.
This paper will focus on the effect of implementing UN R.135 and, specifically, on the differences found by using the WorldSID (World Side Impact Dummy) 50th Percentile Dummy instead of its predecessor (EuroSID-II) for this test.
The above-mentioned side impact test will consist of a side impact test at 32 km/h against a rigid pole. The tested vehicle will be rotated 75° from the direction of impact and the only vehicle occupant will be a WorldSID dummy in the driver position.
WorldSID is the latest generation side impact dummy. Unlike EuroSID-II, WorldSID has an excellent level of biofidelity, replicating human kinematics and sensitivity to injury in a much better way than EuroSID II. Because of this and considering that side impact crashes correspond to approximately 25% of the total amount of serious-to-fatal injuries, using this dummy to evaluate occupant protection in side impact scenarios is a remarkable improvement in vehicle safety.
This paper intends to explain the differences between WorldSID 50th percentile dummy and EuroSID-II as well as indicating the main biomechanic-related topics to be taken into consideration during the vehicle development phase when using WorldSID according to UN R.135.
