Overload Characteristics Analysis of Electromagnetic Release with Oil Dashpot Based on ADAMS

Abstract

In the analysis for overload characteristics of electromagnetic release with oil dashpot, it was difficult to calculate the dynamic behavior of the oil dashpot having long strokes and moving slowly. A method using finite element analysis to obtain the dynamic characteristics of the plunger in the oil dashpot has been developed. Based on the result of the static characteristics, the dynamic characteristics of oil dashpot release are simulated by using ADAMS. Then the relation between the oil damping coefficient and the plunger’s stroke has been discussed. As a result, it is facile to realize the regulation of tripping time for the release through changing the viscosity of silicon fluid.
