Abstract

Whiplash injuries often occur in motor vehicle collision accidents. This injury frequently occurs in the cervical region. However, the reason for this has not yet been clarified. In this study, a multi-body neck model with muscles was designed. Some muscles in the model were preloaded; these were previously determined using the concept of the follower load. Cervical spinal vertebrae, discs, and muscles were designed in accordance with the human cervical spine. The purpose of this study was to investigate the effect of preloads on muscles. The results imply that the whiplash model with preloaded muscles simulates practical situations more closely than models without preloads.

자동차 충돌에 의하여 편타성 손상이 일어나게 되는데, 대부분 경추부분에서 발생한다. 이러한 편타성손상의 메카니즘은 아직까지 명확히 밝혀지지 않고 있다. 본 논문에서는 다물체 경추에 근육을 부착한 모델을 만들고, 부착된 근육에 follower load 개념에 근거한 최적화방법을 이용하여 계산된 초기힘(preloads)를 가하였다. 경추모델에서 추체, 추간판 및 근육은 인간의 해부학적 정보와 일치시켜 제작되었다. 이번 연구의 목적은 경추모델에 부착된 근육에 초기힘이 존재할 때 초기힘의 편타성 손상에의 영향을 조사하는 것이다. 결론적으로, 초기힘이 존재하는 근육-경추모델의 경우가 초기힘이 존재하지 않는 모델에 비하여 좀더 실제와 일치하는 경향성을 보여주었다.
