Abstract:

Choosing reasonable track structure is the most effective method to reduce vibration in this field.The performance of vibration reduction depends on the type of track structure and their pamameters.By establishing an metro vehicletrack system dynamic model,an analysis is made of different dynamic performance parameters of track structure,and the impact of track dynamic parameters on the vibration elimination performance.

Key words:track structure; vibration; dynamical simulation; dynamics
