CAHCTR04092 TEST REPORT <br />A&amed <br />Pmd,KtE Mmtw 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 CFC180 per the <br />IIHS 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 />[a,' <br />y2 , 1112 [ <br />ar= ax +a +a 11 <br />The velocity of each vehicle accelerometer was calculated as shown in equation 2. <br />vx = f axdt + v, (0) [2] <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 />Ovx = V. - vx(o) [31 <br />The resultant delta velocity was calculated as shown in equation 4. <br />Avg = [AVx2 + AVy2 + AV, 21112 [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 is 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 />t2 25 <br />HIC(15)= (1/(t2—t1) f a,dt] N—t1) [5] <br />t, <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 = (FZ I FZ,) + (M,CY 1 M"�) 161 <br />FZ is the axial load and Mo,y is the fore -aft bending moment about the occipital condyle. These <br />parameters were normalized by the critical values FZ, and MyC, referenced from SAE J17273. <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 consent of CAPE <br />Page 9 of 14 <br />
