0213 Study of Human Stepping Model and Synchronization of Walking Rhythm
Details
A human's gait rhythm changes into the frequency of the ground vibration from one's natural gait rhythm. This phenomenon is called as "pull-in effect". It is known as a cause that London Millennium Bridge closed soon after it had opened. The pull-in effect has been investigated by means of the neural oscillator and active motion to avoid falling. But the purpose of these studies was explanation of pull-in effect qualitatively and few studies have focused on the quantitative analysis. In this research, dynamics model was improved. New model can be expected to have good frequency range of pull-in effect and give good horizontal excitation power. Simulation result of phase difference between bridge and human corresponds to experimental result. In order, to evaluate pull-in effect of a real pedestrian bridge, simulation of walking on the free platform was carried out. In conclusion, a quantitative analysis of the pull-in effect became possible with the use of improved passive walking model.
