Three-Dimensional Dynamic Modeling of the Human Knee Joint

这项研究的目的是 发展出一种三维动态的 人体数学模型 膝关节先前 三维模型， 都是静态或准静态的 因此，模型不能 预测动态影响 惯性载荷发生在许多 自发活动 只 二维动态模型 至今被调查。 将开发的模型 将由两个身体部分组成， 股骨和胫骨， 韧带力 变化 在关节位置随时间发生， 联合反作用力，接触 股骨和 胫骨和韧带的力量将是 计算了 这项研究很重要，因为它 将导致一个更完整的 膝盖受伤的知识 发生. 对膝盖的伤害最大 发生在动态的情况下， 这是这个项目的重点。 将开发的方法 也可用于建模 其他关节。

The goal of this research is to develop a three-dimensional dynamic mathematical model of the human knee joint. Previous three-dimensional models either have been static or quasi-static and, therefore, the models cannot predict the effects of dynamic inertial loads which occur in many locomotor activities. Only two-dimensional dynamic models have been investigated to date. The model that will be developed will consist of two body segments, a femur and a tibia, constrained by ligamentous forces. Changes that occur with time in joint position, joint reaction forces, contact point locations between femur and tibia, and ligament forces will be calculated. This research is important since it will lead to a more complete knowledge of how knee injuries occur. Most damage to the knee takes place in dynamic situations, which is the focus of this project. The approach that will be develop also could be used in modeling other articulating joints.
