Abstract

t is important for dynamic characteristics of electromagnetic release with oil dashpot to calculate the oil damping force. The formula of the oil damping force is deduced by the theoretical formula of viscous damper or according to the experimental results. Therefore, a way to analyze oil damping force of electromagnetic release with oil dashpot is proposed based on Fluent due to the limitations of the two methods in this paper. The curve which is the speed of the plunger variations of the oil damping force is drawn through the numerical analysis of the flow field and the index of the speed is fitted.
