The basic principles of impulse response analysis were introduced in this article, the FEM model of an electromagnetic valve was established, then the impulse response analysis of the electromagnetic valve was carried out based on elasticity, the distribution of Von Mises stress was obtained. The results show that the electromagnetic valve structure cannot withstand the given impact load, and it is consistent with the experiment.
