CACTRO4092 TEST REPORT <br />Advon(ed <br />Noduct tulvaW Analysis <br />All inistrumentation data was filtered as specified by SAE J211-12, with the exception of the <br />�EuroSID-2re rib deflections. The EuroSID-2re rib deflections were filtered at CFC1 80 per the <br />INS side impact protocol. Vehicle and ATID calculations were performed per SAE J17273 and <br />the supplemental equations shown below. <br />The bullet vehicle, target vehicle, and the instrumented ATD's were equipped with tri-axial <br />accelerometers. The resultant acceleration (ar) of each tri-axial accelerometer set was calculated <br />as shown in equation 1. <br />a, = [a,'+ ay'+ a,T' <br />The velocity of each vehicle accelerometer was calculated as shown in equation 2. <br />t <br />vx = f axdt + v,,(0) <br />0 <br />Delta velocity of each vehicle accelerometer was calculated as shown in equations 3 and 4. <br />Equations 2 and 3 show the x direction, but the equations also apply to the y and z directions. <br />Avx = VX — vX(0) <br />The resultant delta velocity was calculated as shown in equation 4. <br />AV, = [AV,2 + AV 2 + AvZ211/2 <br />Y <br />Ill <br />[a <br />[31 <br />[a <br />The head injury criteria (HIC) is based upon the probability of linear skull fracture when the, head <br />is subject to direct contact or impact with an object such as the B-pillar, A -pillar, or an interior <br />surface. The HIC is calculated per SAE J17273, FMVSS2084, and FMVSS 2145 as shown in <br />equation 5, and is, the maximum value obtained from al 5 ms time interval of the resultant head <br />acceleration curve. <br />t2 2.5 <br />HIC(15) = [1/(t2 — t1) f ardt] (t2— t1) <br />t, <br />[5] <br />The neck injury index (Nij) is a value that indicates the probability of neck injuiry based on neck <br />axial loading and neck flexion/extension moment. The Nij is calculated per SAE J17273, and <br />FMVSS2084 as shown in equation 6, <br />Nij = (F7 / F7,) + (Macy / MyJ <br />[a <br />F I is the fore -aft bending moment about the occipital condyle. These <br />,, is the axial load and M.., <br />parameters were normalized by the critical values F,, and MY., referenced from SAE J 1727,3. <br />Information contained in this document is confidential and may not be transmitted or reproduced, <br />in full or in part, for any purpose without the written consont of CAPE. <br />Page 9 of 94 <br />
