跑步过程中膝关节生物力学研究
Biomechanical research of knee joint during the process of running
摘要
Abstract
To study the effect of speed on the biomechanics of a knee joint during running,a biomechanical model of human lower limb joints is established based on the Kane method and semi-physical simulation.Experiments on the running process were made at different speeds for healthy young men.The influence of running speed on knee joint motion is analyzed quantitatively and a mathematical model of the knee angle is established with speed as the independent variable.Results show that,at the moment of the heel contacting with the ground,with the increase of speed,the calf stretches forward more,and the calf and thigh are closer to the same line.In the middle stage of a gait cycle,the thigh stretches back,and then the calf and thigh are close to collineation.At that moment,the stretch of the posterior cruciate ligament is the largest,and the slower the speed,the more obvious the collineation.The maximal joint angle of the calf relative to the thigh appears in the later stage,and the maximal joint angle increases with the increase of the velocity.With the increase of the rtmning speed,the phase of the curve of knee angle moves forward.The results can be used in the field of rehabilitation robotics and humanoid robot.关键词
