9、impact response is defined as the reaction of a body segment in terms ofmeasurable engineering parameters such as forces, accelerations, and deflections due to direct or indirect impactloading. The impact response of a body region can depend upon the test conditions used to generate the data(such as

10、 impactor shape, stiffness, mass, and body region boundary conditions) and thus, in most cases, can onlybe defined in terms of those conditions. Accordingly, the impact response of a test dummy component must beevaluated under test conditions similar to those used to obtain the defined response data

11、.A number of problems need to be addressed in defining human impact response characteristics, since mostimpact response studies use cadaver or animal surrogates to obtain data at severe impact levels. The impactresponse of surrogates can differ from that of living humans due to lack of physiological

12、 effects, such as muscletone in the cadaver subject, and lack of geometric similitude with animal subjects. In cases where sub-injury testsare conducted with volunteers, there are also problems with extrapolation of the response data to represent theresponse at higher impact severities. Some studies

13、 only include response of the body region up to the injuriouslevel while others include response well beyond the initiation of tissue structural failure associated with injury.In addition, the human form is not of unique size, shape, and proportion. There are significant geometricdifferences between

14、 and among adults and children, and males and females. The available response data in theliterature dictates that treatment of this topic be constrained essentially to guidelines for average adult maleresponses, with scaling used to define equivalent responses for the small adult female and the larg

15、e adult male.Finally, there may be response variability introduced by age, physical conditioning, and other factors not discussedhere. This variability is discussed for those body regions where such information is available.1. ScopeThis series of reports provides response characteristics of the head

16、, face, neck, shoulder, thorax,lumbar spine, abdomen, pelvis, and lower extremities. In each report, the descriptions of human impactresponse are based on data judged by the subcommittee to provide the most appropriate information for thedevelopment of human surrogates.Copyright SAE International Pr

The

18、se reports update SAE J1460 which is intended for use by anthropomorphic testdummy designers and analytical modelers who need quantitative definitions of human mechanical impactbehavior. These reports do not discuss criteria for assessing human impact injury potential, which are thesubject of SAE J8

19、85. Each document in the series covers material specific to a body region and will beindependently updated when new response data become available. The goal of this report is to characterizethe response of human neck due to head inertial loading when the occupant is sitting in an automotive posture.

IntroductionIn automotive collisions, the neck plays an important role in controlli

40、ng the kinematics of thehead. The primary neck characteristics affecting the resulting head kinematics are its length, range ofarticulation relative to the automotive seated posture and degree of bending resistance produced by active andpassive muscle reactions and by ligament stretch. For a crash t

41、est dummy to have human-like head motion,its neck structure must be designed to mimic these important characteristics. In addition, the crash testdummy needs to be instrumented to measure internal neck loads to assess the potential for neck injury. Thisreport will provide a summary of studies conduc

42、ted to quantify neck response characteristics produced by fore,aft, and lateral head inertial loading. Performance requirements for judging neck biofidelity based on thesedata will be given. The SAE sign convention defined in SAE J211 and SAE J1733 is used in this report (seeAppendix A). Response of

Neck Anato

44、myThe primary load-carrying structures of the neck are the cervical spine, intervertebral disks,ligaments, and muscles. The cervical spine consists of seven bony vertebrae commonly referred to as C1through C7 (see Figure 1). The top two vertebrae have unique shapes and functions. The top vertebra, C

45、1, iscalled the atlas, and is shown in Figure 2. It supports the head at two bony articular surfaces called theoccipital condyles which are symmetrically located on the base of the skull on each side of the foramenmagnum, the hole through which the spinal cord passes, (see Figure 3). This joint allo

46、ws the head to nod fore-aft relative to C1 without unduly stretching the spinal cord. The second cervical vertebra, C2, is called the axisand is shown in Figure 4. It is characterized by a bony protuberance, the odontoid process, which extendsupwards into the atlas. The odontoid process forms an axi

47、s for head rotation as in the “no” gesture. The thirdthrough seventh cervical vertebrae, C3 through C7, are similar to the other vertebrae of the spine with theirsize increasing as one proceeds down the spine, (see Figure 5). These vertebrae have smooth superior andinferior bony surfaces called face

48、ts which form articular joints with adjacent vertebrae. The bodies of C2through C7 are separated by fluid-filled fibrous pads called intervertebral disks. The amount of relative motionthat can occur between adjacent vertebrae is limited by the articular joints and intervertebral disks as well asby f

49、ibrous tissue called ligaments which bind adjacent vertebrae together. Figure 6 is a lateral cross-sectionalview of the base of the skull and of C1 and C2 which shows various ligaments, articular joints, intervertebraldisks, and the spinal cord canal.
