1. Jorlöv, Sofia. Comparison Study of the Two Pediatric ATDs: Hybrid III 6-Year-Old and Q6.

Degree: Biomechanics and Biomedicine, 2011, Halmstad University

As a new pediatric dummy family, the Q-family, is suggested for the European childsafety regulations (R44) and the updated EuroNCAP, it needed to be tested andcompared to the older pediatric dummy family, Hybrid III, used in testing at Autolivtoday.In this study, tests were performed with the Q6 and the Hybrid III 6-year-old. Bothdummies were subjected to eight sled tests using a EuroNCAP acceleration pulse. The sled represented the interior of a Volvo V70, with integrated booster cushions mounted onto the car body through a rigid fixture. Standard belt were used for all tests, except one where pretensioning was used. Static tests investigated how the chest deflection on Q6 was affected by the shoulder belt geometry. Large difference in belt interaction was observed between the dummies. The beltslipped off the Hybrid III’s shoulder for all tests except one, while the belt on the Qdummy’swas hard to provoke off the shoulder. The overall kinematic behavior, beforethe belt slipped off the Hybrid III’s shoulder, were similar for both dummies. Differences in chest deflection on the Q6, depending on the belt geometry, were observed in both the dynamic and the static tests; a shoulder belt geometry closer to theneck resulted in minor displacement than a mid-shoulder belt geometry. After testing, five different damages were observed on the Q6.

<ol>Då en ny familj av barnkrockdockor, Q-familjen, är föreslagen för det europeiskalagkravet som reglerar barnsäkerhet (R44), uppstod ett behov av att testa och jämföradessa mot den äldre familjen av barnkrockdockor som används vid testning på Autoliv idag, Hybrid III. I den här studien utfördes tester på Q6 och Hybrid III 6 år. Båda dockorna utsattes föråtta stycken slädtest i en accelerationspuls enligt EuroNCAP. Släden representerade enVolvo V70 med integrerade barnkuddar som monterats i riggen via en stel fixtur. I alla test utom ett användes standardbälten (i undantagsfallet användes försträckare). Statiska tester gjordes för att undersöka hur Q6 påverkades av olika geometrier på axelbältet. Stora skillnader observerades mellan dockornas bältesinteraktion. Bältet gled av HybridIII:s axel i alla test förutom ett, medan det istället var svårt att provocera av bältet från Q-dockans axel. Innan Hybrid III gled ur bältet var dockornas kinematik liknande. I både statiska och dynamiska tester observerades skillnader i bröstintryckning på Q6, beroende på bältesgeometrin; en geometri där axelbältet var placerat nära nackenresulterade i en mindre intryckning än då axelbältet var placerat mitt på axeln. Efte ravslutad testning upptäcktes fem skador på Q6.</ol>
