摘要: The forces during the kicking phase in Nordic diagonal stride skiing are described by differential equations and results compared with experiments. difference between static dynamic friction, interacting characteristics of skier such as weight, velocity force's angle terrain, essential for high-velocity striding. Analytical relationships glide length, friction force shown. Aerodynamic drag gravity accounted for. A propulsion based on Hill (1970) equation muscle contraction activation is constructed. model shows a feasible tool studying effects ski stiffness, amount waxing skiing.
