Research on Somatosensory Simulation of Alpine Skiing

This paper studies the somatosensory simulation problem in alpine skiing. A single rigid body system of body mass center-ski mass center is established, and a dynamic model describing alpine skiing is obtained through the analysis of the system's force and the slalom state. Combining the dynamic model with the washout algorithm, the pose of the 6DoF parallel motion platform is obtained, and the motion simulation of multiple degrees of freedom is realized. In order to obtain the best washout parameters for skiing, the objective function is designed and the DE algorithm is used to optimize the parameters. After the optimization, the perception error and the perception delay are reduced and the false perception is eliminated. The simulation and experimental results show that the research on the alpine skiing dynamics model and optimized washout algorithm can achieve the real somatosensory simulation effect.
