Rational value forεin EP method;

EP法中参数ε的合理取值

In order to study the 3D static performance of EP solenoid valves in the electro-pneumatic braking system of a passenger train, the 3D FEM model and mathematical model were established according to axisymmetric structural feature.

针对EP阀轴对称的结构特点,建立有限元分析模型。
