The impact of waves on the legs is a typical action in the sport of surfing at sea, and it is also an action that causes the body to be damaged. With the dynamic analysis of the burst of the waves on the legs in the sport of surfing on the sea, the analysis of the generating force is carried out. Because of the non-linear characteristics of ARMA model, the accuracy of finite element mechanical analysis of human leg force is not good for the motion model which has strong inertia mechanics effect of wave impact on leg. Based on the characteristic decomposition model of inertia mechanics, this paper presents a dynamic analysis model of wave impact on the legs of human body in the sea surfer movement, and analyzes the burst kinetic energy of the wave impact on the leg in a six-degree-of-freedom space. First, the forward kinematics algorithm is used to obtain the finite element space of the force on the legs of the human body, and the kinematics solution of the moment of shock of the waves is realized by the analytic method. The global and local parameters of the human leg force and contact force during the wave impact on the legs are analyzed, and the precision of solving the parameters is improved. The simulation results show that the method can be used to analyze the mechanics of the human leg in the moment of wave impact in the sea surfing. The parameter estimation is accurate and reliable and the performance is superior. The method can effectively guide the training of the sea surfing sport.
