Testing procedure Crash test dummy

hybrid iii undergoing calibration

every hybrid iii undergoes calibration prior crash test. head removed , dropped 40 centimetres test calibrate head instrumentation. head , neck reattached, set in motion, , stopped abruptly check proper neck flexure. hybrids wear chamois leather skin; knees struck metal probe check proper puncture. finally, head , neck attached body, attached test platform , struck violently in chest heavy pendulum ensure ribs bend , flex should.

when dummy has been determined ready testing, calibration marks fastened side of head aid researchers when slow-motion films reviewed later. dummy placed inside test vehicle, set seating position , marked on either head , knees. fifty-eight data channels located in parts of hybrid iii, head ankle, record between 30 000 , 35 000 data items in typical 100–150 millisecond crash. recorded in temporary data repository in dummy s chest, these data downloaded computer once test complete.

because hybrid standardized data collection device, part of particular hybrid type interchangeable other. not can 1 dummy tested several times, if part should fail, can replaced new part. instrumented dummy worth €150,000.

positioning , restraints

children in three-year old age group more have fatality because age positioning crucial. in countries, children transition facing rear of car facing front @ age. study done on restraints , positioning of three-year olds. concluded being restrained , in front seat has lower fatality rate children positioned in seat not restrained. safety results indicated children should placed in seat , restrained. suggests restraints have bigger impact on safety seating positions. lap belt used on children not provide safety adult, due flexibility of children. adult seatbelt more harm child good, why children should utilizing child restraint system instead. system includes booster seat , proper belt fits child s criteria including age, weight , height.

specialized dummies

hybrid iiis designed research effects of frontal impacts, , less useful in assessing effects of other types of impact, such side impacts, rear impacts, or rollovers. after head-on collisions, common severe injury accident side impact.

worldsid advanced side impact atd, used euroncap side impact test modes.



the sid (side impact dummy) family of test dummies designed measure rib, spine, , internal organ effects in side collisions. assesses spine , rib deceleration , compression of chest cavity. sid united states government testing standard, eurosid used in europe ensure compliance safety standards, , sid ii(s) represents 5th-percentile female. biosid more sophisticated version of sid , eurosid, not used in regulatory capacity. worldsid project develop new generation of dummy under international organization standardization.
biorid dummy designed assess effects of rear impact. primary purpose research whiplash, , aid designers in developing effective head , neck restraints. biorid more sophisticated in spinal construction hybrid; 24 vertebra simulators allow biorid assume more natural seating posture, , demonstrate neck movement , configuration seen in rear-end collisions.


12-month old crabi dummy in child safety restraint seat.



crabi child dummy used evaluate effectiveness of child restraint devices, including seat belts , air bags. there 3 models of crabi, representing 18-month, 12-month, , 6-month-old children.
fgoa first generation obese anthropometric test device can used study automotive safety challenges obese occupants, believed have higher risk of mortality in automobile collisions comparing non-obese occupants.


thor offers sophisticated instrumentation assessing frontal-impacts



thor advanced 50th percentile male dummy. successor of hybrid iii, thor has more human-like spine , pelvis, , face contains number of sensors allow analysis of facial impacts accuracy unobtainable other dummies. thor s range of sensors greater in quantity , sensitivity of hybrid iii. thor s original manufacturer, gesac inc., ceased production after slowdown of auto industry in late 2000s. thor being further developed, , 2 other companies working on similar dummies; nhtsa s ultimate goal government-funded project development of single thor dummy, thor dummy development stopped. ftss, bought humanetics, , dentonatd both continued produce thor lx , thor flx.
animal models have been used test safety of dog harnesses , crates in crash conditions.
