Basic Mechanics of Boot/Skier Interaction


A two-dimensional point mass model of a skier with three plus one degrees of freedom has been developed. A general method for obtaining the equations of motion and of the constraint forces (muscle forces and forces between the ski and soil) in such models is described (by the method of undetermined Lagrangian multipliers). The force and torque transduced from skier to ski by the boot and the biological components of the system are calculated. The results provide a theoretical basis for recommendations that the important parameters for ski boots should include the size, weight, and skill of the skier.
