摘要：

Pole vaulting has progressed slowly in terms of performance since the 1960's. The world record varies by a few centimeters due to the use of flexible poles. In this research, we propose a new stochastic optimization approach to take into account the uncertainties. A simplified mass-spring model has been implemented to model the pole vault. This model is considered as a tool to explore the possibilities of trajectories and performances, in which the parameters associated with this system are uncertain. This approach is based on the association of the perturbation method with the fourth order Runge-Kutta method (RK4). The new stochastic approach is used to optimize the dynamic response of the system and the computation time. The results of the perturbation method (PM) are compared to those of the reference Monte Carlo method (MC).
