摘要: 在已有的由湖南大学开发和验证的人体颈部有限元模型的基础上,对其进行诸多改进和优化,并在低速的正面、侧面和后碰撞工况下重新进行验证。模型包括了颈椎椎骨、椎间盘、韧带和肌肉等软组织结构,各个部分分别用不同的单元类型模拟。借助美国海军生物动力学实验室(NBDL)和瑞典查尔摩斯大学进行的实验数据对改进后的模型进行了验证。结果表明:模型在主要响应阶段与实验数据吻合得较好,模型具有较好的生物逼真度。

Abstract: An FE (finite element) neck model was improved with human like response in vehicle frontal, rear-end and side collisions based on an existing model developed in Hunan University. The model consists of the cervical vertebrae, intervertebral discs, ligaments and muscles that are modeled with various element types. The model was validated against kinematics data from volunteer tests carried out at the Naval Biodynamics Laboratory (NBDL) and Chalmers University of Technology. The results show that the model has good biofidelity with a good agreement with the test results for the main part of the time history of the collision events.

Key words:  vehicle collisions, human neck, finite element model, kinematics response, validation
