Research on dynamic performance of tilting train with active air spring control
In order to study the dynamic performance of the tilting train based on the active air spring control technology
a nonlinear vertical model of the air spring and the system dynamics model of the tilting train were established
incorporating the connecting pipeline
the additional air chamber and the tilting valve. The co-simulation of multi-body dynamics software Simpack and numerical calculation software Simulink was applied to explore the dynamic performance of the tilting train running on a curve at a high speed. The influence from angle stiffness of the anti-roll torsion bar on train tilting under the active air spring control was analyzed. The suspension parameters such as the lateral stopper stiffness and lateral stiffness of the air spring were optimized to ensure the running stability of the train on curves. The results show that the active air spring control technology can reduce the unbalanced centrifugal acceleration experienced by passengers and increase the curve negotiation speed without changing the bogie structure and track conditions. The vertical stiffness of the air spring should be well matched with the anti-roll angle stiffness
and the anti-roll angle stiffness should be reduced as far as possible under the premise of meeting the flexibility coefficient
to reduce the tilting resistance and relieve the pressure fluctuation of the air spring. In consideration of the fact that the active air spring control technology causes swaying increase between the carbody and the bogie
resulting in the carbody collision with the lateral stopper
reasonable matching between the lateral stiffness of the air spring and the lateral stopper stiffness can effectively reduce the carbody swaying
avoid hunting instability of the train passing on a curve with a large deficient superelevation
and improve the curve negotiation performance of the train.
