ViVA Open Human Body Model (HBM) is an open-source human body model that was developed to fill the gap of currently available models that lacked the average female size. In this study, the head-neck model of ViVA OpenHBM was further developed by adding active muscle controllers for the cervical muscles to represent the human neck muscle reflex system as studies have shown that cervical muscles influence head-neck kinematics during impacts. The muscle controller was calibrated by conducting optimization-based parameter identification of published-volunteer data. The effects of different calibration objectives to head-neck kinematics were analyzed and compared. In general, a model with active neck muscles improved the head-neck kinematics agreement with volunteer responses. The current study highlights the importance of including active muscle response to mimic the volunteer's kinematics. A simple PD controller has found to be able to represent the behavior of the neck muscle reflex system. The optimum gains that defined the muscle controllers in the present study were able to be identified using optimizations. The present study provides a basis for describing an active muscle controller that can be used in future studies to investigate whiplash injuries in rear impacts.

在低严重性后部碰撞碰撞中优化具有主动反射颈肌的女性头颈部模型。

ViVA 开放人体模型 (HBM) 是一种开源人体模型,旨在填补当前可用模型缺乏平均女性尺寸的空白。在这项研究中,ViVA OpenHBM 的头颈部模型通过为颈部肌肉添加主动肌肉控制器来进一步开发,以代表人体颈部肌肉反射系统,因为研究表明,颈部肌肉在撞击过程中会影响头颈部运动学。通过对已发布的志愿者数据进行基于优化的参数识别来校准肌肉控制器。分析比较了不同标定目标对头颈部运动学的影响。一般来说,具有活跃颈部肌肉的模型改善了志愿者反应的头颈部运动学一致性。当前的研究强调了包括主动肌肉反应以模拟志愿者运动学的重要性。已经发现一个简单的 PD 控制器能够代表颈部肌肉反射系统的行为。在本研究中定义肌肉控制器的最佳增益能够使用优化来确定。本研究为描述可用于未来研究的主动肌肉控制器提供了基础,以研究后方碰撞中的挥鞭伤。
