基于动作捕捉技术的人体上肢运动舒适性评价
Evaluation of human upper limb motion comfort based on motion capture technique
摘要
Abstract
Biomechanical study of human upper limb is one of the most referenced aspects for the optimization of upper limb posture and the design of related products .Firstly,a real-time optical motion capture system was used to capture the real-time position of key points of the human body in the course of executing the specified action .The focus of the work was to calculate and deeply analyze the experimental data of the human upper limb by MATLAB software .Then,the human upper limb was simplified as a club model,and the variation value of each joint angle of the hu-man upper limb during the motion process was calculated by the cosine theorem .The dynamic joint torque was computed by the inverse dynamics and the change of main muscle force was cal-culated by the optimization analysis .Lastly,the human upper limb motion comfort was evaluated by calculating the real-time load rate of human upper limb muscles,and the motion comfort index evaluation model of human upper limb was established .The experiment result proved that the human upper limb muscles were in the comfort state when the body executed the specified action at a sitting posture .The results provide a theoretical basis for the depth analysis of human upper limb motion .关键词
