    Abstract
  • In order to discuss the effect of vehicle stopping block on vehicle dynamics, a dynamics model of secondary lateral stopping block was put forward, and its characteristics of dynamic interaction and stopping displacements in time and frequency domains were analyzed.Analysis result shows that the model has strong nonlinearity, stopping block can effectively restrict the lateral displacement of vehicle, and it decreases by 30 mm; the block has great influence on the lateral vibration of vehicle, the lateral force of wheel-rail has fluctuation in curve, the main frequency of the block is not more than 4 Hz, and its range accords with the main frequency range of lateral vibration acceleration of vehicle.
