Analysis on the Impact of Dynamic Braking Manipulation on the Decoupling of Intermediate Locomotive
The numerical simulation calculation is conducted for the decoupling of intermediate locomotive of the 20 000-ton heavy haul train,mainly analyzing the impact of the change of dynamic braking conditions on the decoupling.The simulation calculation result shows the following:the probability of decoupling is higher at the key sections of line;by changing the dynamic braking force,the vertical misalignment between coupler heads can be reduced to a certain extent,which can reduce the risk of decoupling;by changing the time of dynamic braking manipulation to avoid the application of dynamic braking at key sections of line as much as possible,the risk of decoupling of intermediate locomotive can be effectively reduced.
