| Abstract: | In the electro pneumatic breaking system, the dynamic performance of the electro pneumatic brake solenoid valve directly determines the train safety. To improve the sensitivity and reliability, the solenoid valve armature clearance, coil turns, spring preload and other major structural parameters were adjusted based on the law of electromagnetic wave energy flow fluctuation and its influence on the dynamic characteristics of valve during action process. The dynamic electromagnetic field range of changes was controlled, and the performance parameters were optimized. It is found that the electromagnetic field energy output was reduced and the operating temperature rising velocity was decreased. |

| Keywords: | train braking solenoid valve dynamic analysis simulation and optimization |
