“…The development of more sophisticated and anatomically accurate models of the human cervical spine using finite element models (FEM) to study cervical-spine injury has provided the motivation for the current study [16][17][18][19][20][21][22][23][24][25][26]. FEM are used to study how variations in initial head/neck posture, cervical-spine curvature, and occupant age/gender/stature affect the likelihood of neck injury in rear MVC, because results of laboratory studies indicate that the likelihood of injury may depend on the initial alignment of the vertebrae [27,28].…”

Knowledge of the distributions of cervical-spine curvature is needed for computational studies of cervical-spine injury in motor-vehicle crashes. Many methods of specifying spinal curvature have been proposed, but they often involve qualitative assessment or a large number of parameters. The objective of this study was to develop a quantitative method of characterizing cervical-spine curvature using a small number of parameters. 180 sagittal X-rays of subjects seated in automotive posture with their necks in neutral, flexed, and extended postures were collected in the early 1970s. Subjects were selected to represent a range of statures and ages for each gender. X-rays were reanalyzed using advanced technology and statistical methods. Coordinates of the posterior margins of the vertebral bodies and dens were digitized. Bézier splines were fit through the coordinates of these points. The interior control points that define the spline curvature were parameterized as a vector angle and length. By defining the length as a function of the angle, cervical-spine curvature was defined with just two parameters: superior and inferior Bézier angles. A classification scheme was derived to sort each curvature by magnitude and type of curvature (lordosis versus S-shaped versus kyphosis; inferior or superior location). Cervical-spine curvature in an automotive seated posture varies with gender and age but not stature. Average values of superior and inferior Bézier angles for cervical spines in flexion, neutral, and extension automotive postures are presented for each gender and age group. Use of Bézier splines fit through posterior margins offers a quantitative method of characterizing cervical-spine curvature using two parameters: superior and inferior Bézier angles.

“…The skin, muscle and internal organs were modelled with viscoelastic materials, while the cartilages and ligaments were modelled with elastic materials. The material parameters of the thoraxabdomen tissues were summarised from the test data reported in the literature (Zhao and Narwani, 2005;Ruan et al, 2003a;Ruan et al, 2003b;Ruan et al, 2005;Iwamoto et al, 2002;Jost and Nurick, 2001;Lizee et al, 1998;Wang, 1995;Huang et al, 1994;Plank and Eppinger, 1989) and were calibrated in model validation. Table 1 lists the main material properties for the tissues of the thorax-abdomen model.…”

“…With the advancement of computer-aided techniques and numerical methods, some detailed FE models of part or full human body have been developed by peers to investigate the injury mechanisms of occupants' thorax and abdomen in vehicle collision accidents (Ruan et al, 2003a;Ruan et al, 2003b;Ruan et al, 2005;Thollon et al, 2002;Howard et al, 2000;Iwamoto et al, 2002;Jost and Nurick, 2001;Lizee et al, 1998;Wang, 1995;Huang et al, 1994;Plank and Eppinger, 1989;Plank and Eppinger, 1991). These models replicate the anatomical structures and physical characteristics of the real human body.…”

Abstract:In this study, a Finite Element (FE) model of adult occupant was developed to investigate the thoracic and abdominal injuries caused by seat belt wearing. A model geometry was created from the CT data of a volunteer representing the 50th percentile Chinese male. The anatomical structures and physical characteristics were modelled the same as those in the real human body. Especially the thorax and abdomen model included details of the ribcage, thoracic and lumbar spine, pelvis, internal organs, skin, muscles, ligaments, main arteries and veins, and other soft tissues. Through simulations against Post-Mortem Human Subjects (PMHS) tests of seat belt loading, good agreements were achieved between them in terms of the force and deflection responses and injury distributions. Moreover, the effective analyses of seat belt design parameters indicated that the belt fabric tape stiffness, pre-tension force and upper slipping position played an important role on the thoracic and abdominal injuries.Keywords: seat belt; thoracic and abdominal injury; biomechanical response; effect analysis; finite element model.Reference to this paper should be made as follows: Ma, Z., Chen, J. and Lan, F.

“…The Finite Element method provides an extraordinary opportunity to explore the dynamic responses of the human body to impact loading especially in a vehicular crash scenario. In recent years, several finite element moclels have been developed to study human body iajury mechanisms in vehicular impacts (Happee et al, 1998, Howard et al, 2000, Fumsu et al, 2000, Iwamoto et al, 2002, Jost and Nurick, 2001, Lizee et al, 1998, Thollon et al, 2002. These models have shown promise as usefu1 tools to better understand impact problems and therefore could reduce the dependence on cadaveric test studies.…”
