Plunger and core parameter modeling research of cylinder valve in hydrogen fuel cell vehicles

Altering the shape of the plunger and the core changes the working air gap of cylinder valve in the hydrogen cell car. The electromagnetic force can change greatly depending on the design of the internal end of the plunger and the core. The Plunger and core parameters are selected based on large amounts of finite element experiments in the design. Sometimes this work cannot be completed actually. This paper presents a model which input is the plunger and core parameters and output is the force based on support vector machine. Simulation analysis indicates that this model has high learning speed, good approximation, well generalization ability.
