摘　　要：目的建立肘关节矢状面内的动力学模型,寻求有效方法进行求解。方法利用Matlab的优化工具箱对所建立的模型进行优化求解。结果求解出了肘关节在不同屈伸角速度下,受到不同外力时的关节反力、各肌肉力以及力矩,得出了与文献相一致的结论。结论利用Matlab的优化工具箱可以合理地求解该模型,并且该模型可以用来计算肘关节在受到不同外力时的关节反力、肌肉力以及相应力矩。Objective To establish a human elbow joint dynamical modelling in the sagittal plane and seek for an impactful way for solution. Methods To use the optimization toolbox of Matlab for optimizing and solve the modelling. Results The muscle contraction, joint reaction and their corresponding moments were obtained when different external force was applied to the forearm at different elbow joint angle velocity, and it shows that the results are good agree with the literatures. Conclusions The optimization toolbox of Matlab can be used to solve this kind of questions reasonably and the modelling can be used to calculate the muscle contraction, joint reaction and their corresponding moments at the human elbow joint under the application of different external force.
