<br />Nodvo (4vi6m Analysis
<br />All instrumentation 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 CFC1180 per the
<br />INS side impact protocol. Vehicle and ATD 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 (a,) of each tri-axial accelerometer set was calculated
<br />as shown in equation 1.
<br />ar 7 [ax 2 + ay 2 + az2 1 112
<br />The velocity of each vehicle accelerometer was calculated as shown in equation 2.

<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 />AV,, = V,, — V,,(0) [31
<br />The resultant delta velocity was calculated as shown in equation 4.
<br />AV, = [AVX2 + Avy 2 + AV /V12 [4)
<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 its calculated per SAE J17273, FMVSS2084, and FMVSS 2145 as shown in
<br />equation 5, and is the maximum value obtained from a15 ms time interval of the resultant head
<br />acceleration curve.

<br />The neck injury index (Nij) is a value that, indicates the probability of neck injury 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 = (F, / F,J + (M,,y / MYC) [6]
<br />F, is the axial load and M,,, is the fore -aft bending moment about the occipital condyle, These
<br />parameters were normalized by the critical values F,, and M,,, referenced from SAE J17273,
