The impact of knee mechanics analysis model of high altitude exercise fall, driving torque and dynamic parame- ters of human lower limb joints, provides the model and the data base for the guidance of scientific sports training and sports medicine. Impact mechanics of knee motion analysis of high altitude falling after the traditional method of the knee joint model can solve the local force and force parameters of each joint, knee and lower limb function and the driving force of impact energy parameters modeling difficulty movement. An analysis model of driving air sports fall based on the struc-ture of the seven link rear impact dynamics is proposed. Construction at high altitude after landing leg knee motion of hu-man body even mathematical model, analysis the impact of the kinematic chain knee pose transformation relations, the 7 connecting rod to drive the structure of the human body at high altitude after the fall of the lower limb was decomposed 7 connecting rod structure, the dynamic equation of Lagrange to achieve the overall impact of mechanical parameters analy-sis, obtains the optimization solution vector. Simulation results show that the stress analysis model and stress analysis of the knee impact approximation to the theoretical value, high accuracy, excellent performance, it can provide accurate data ba-sis for sports training and sports medicine.
