Abstract

The mechanism of electromagnetic interference (EMI) is studied for an engine speed acquisition system in this paper. The effect of states and terminal loads is analyzed for the interference signal, which is simulated by using a commercial software. The oscillation of the voltage interference signal is produced by the speed sensor under the radiation of high-altitude nuclear electromagnetic pulse (HEMP), which has been validated by both simulation and experiment. The interference signal can be collected by the speed acquisition system and the normal operation of the engine will be obstructed. The GTEM cell is used for producing the plane wave for the experiment and the speed acquisition controller is used to test the ability of acquisition for interference signals.
