Dynamic Response Analyses for Human-induced Lateral Vibration

Locomotion of animals, such as walking and running, is generated and controlled by the central nervous system called as the central pattern generator (CPG). Recently, the CPG framework has been utilized to develop locomotion controllers for autonomous walking robots. Therefore, a neural-oscillator model is investigated to grasp some useful information for human-induced lateral vibration on congested pedestrian bridges. The dynamic response analysis is also carried out taking into account the neural-oscillator model. Based on these results, it is confirmed that the neural- oscillator might be one of the effective models to explain the synchronization (the lock-in phenomenon) of a fairly high part of all pedestrians being on the bridge.
