Shock attenuation properties in runner-surface coupled system with parameter sensitivity tests

摘要

The purpose of this study is to investigate the influence of parameter variation in human running model on cushioning efficiency of passive load at ground reaction force. The shock attenuation with various patterns of parameter sets were calculated in runner-isurface coupled system by parameter sensitivity tests. In conclusion, significant differences of shock attenuation were observed even in same subject and same running speed because of wide variation of runner model parameters. Additionally, the range of variation of shock attenuation in soft surface was significantly bigger than that of hard surface when the runner parameter was changed +3% from original parameter.
