Abstract:

In this paper, the effect of the section size on the strain energy of vaulting poles is investigated in the static equilibrium condition. The variation of the wall thickness of the vaulting pole along its length is obtained. The deformation curve of the vaulting pole under the ultimate state is computed by Finite Element Method, and the assumption that the ultimate deformation curve is in a form of arc is verified as well. The performance index is modified based on the energy conservation, taking into account the contribution of the vaulter's muscle work to the height of pole vaulting. The computational formula of the vaulting height is derived as a function of the weight, the height of athletes and the pole grasp height.
