摘要：This paper develops a 2-dimensional model to simulate skiing movements based on multibody system. The model includes one rigid ski and five rigid skier's segments (arms, trunk, thighs, shanks, and boots). The ski is modeled as a discrete-point rigid body. A spring-damper element is used to describe the interaction of every point between the ski and snow. The snow ground can be planar or uneven terrains. The air resistance of skier and ski are considered. Finally, several simple skiing movements were simulated. On the one hand, these simulations included some general skiing characteristics such as downhill, rotation, flying, and landing. On the other hand, the snow surfaces could be planar slope, sinusoidal slope, and rampant slope. The results show that the model can simulate simple types of skiing, and can provide kinematic and kinetic data such as the skier's displacement, velocity, acceleration, joint moment and force, and ground reaction force. The model may be useful for building 3-dimensional skiing model, and for further studies of skiing movements.
