A sagittal plane mathematical model for the cervical spine has been used to simulate the neck's response to loads due to high acceleration. The model is capable of simulating the muscular response of the cervical spine and the stress distribution between the joint levels. In order to obtain conservative estimates of the maximum acceleration that the neck can support, the neck was simulated using the assumption that the inertial load is supported primarily by the muscles. It was found that accelerations of up to 30 g can be supported with the appropriate posture and direction of acceleration. Estimates were also obtained using experimental results to approximate the role that the ligaments of the spine play in supporting the load. It was found that accelerations of up to 40 g can be supported for the appropriate posture and acceleration direction.
一个用于颈椎的矢状面数学模型已被用于模拟颈部对高加速度负荷的反应。该模型能够模拟颈椎的肌肉反应以及关节水平之间的应力分布。为了获得颈部能够承受的最大加速度的保守估计值，在假设惯性负荷主要由肌肉支撑的情况下对颈部进行了模拟。结果发现，在适当的姿势和加速度方向下，颈部能够承受高达30g的加速度。还利用实验结果进行了估计，以近似脊柱韧带在支撑负荷中所起的作用。结果发现，在适当的姿势和加速度方向下，颈部能够承受高达40g的加速度。
