摘要:
Chapter 1 Track Dynamics Research Contents and Related Standards
With increasing train speed， axle loads， traffic density， and the wider engineering applications of new vehicles and track structures， the interaction between vehicle and track has become more complex. Accordingly， the train running safety and stability are more affected by increased dynamic stresses. Dynamic loads acted on the tracks by vehicles fall into three categories: moving axle loads， dynamic loads of fixed points， and moving dynamic loads. Axle loads， due to their moving loading points， are dynamic loads for the track-subgrade-ground system， though irrelevant to the vehicle dynamics and constant in size. As soon as the speed of mov
