| Summary: | According to the design requirements and related standards of standard metro train 80B, a vehicle dynamics model was established. Based on the correlation of vehicle system modal characteristics with running speed and suspension parameters, the sensitivity of different variable factors was analyzed by Fourier amplitude expansion method. The optimal design model was established according to the dynamic index, and the suspension parameters of the primary and secondary series were optimally combined. The optimized suspension parameters were used to evaluate the dynamic performance of the vehicle under different working conditions, and combined with the vehicle track coupling dynamic model, the influence of the vehicle body and bogie modes on vehicle stability and vibration was briefly analyzed. The calculation results show that, based on the optimized suspension parameters, the dynamic performance of the standard metro train 80B meets the standards and design requirements, the coupling between the car body and the bogie is weak, and the vehicle system has a certain safety margin. |
