Dynamic Numerical Analysis of the “Foot – Training Shoe“Model

This paper focus on the three - dimensional dynamic research of the”foot - shoe“system. Based on the analysis on the physiology of human foot, the dynamic explicit Finite Element model of the foot and two kinds of training shoes’ sole are established by ANSA, ANSYS, DYNA and other software. Firstly the stress transfer process of falling foot is numerically simulated. Secondly the effective stresses of the foot by the new-fashioned and old-fashioned shoe are compared. Then the load characteristics of the”foot - shoe“model is studied through the acceleration, the energy, etc. Finally the research conclusion and the suggestion are summarized, which prove that the sole with the multilayer structure, anti-torsion bridge design and optimum material selection is very important for absorbing the shock and protecting the human arch, the ankle, etc., which can reduce the stress peak value of about 80%.
