Abstract
The remainders in attached pipelines of rocket engine are great harm to the reliable operation of engine. Signal noise and misjudgment caused by electromagnetic interference reduce the detection accuracy seriously. This paper analyzes the common-mode voltage of the rectifier bridge side and the inverter side of the detection equipment. According to the cut-off frequency, the fundamental voltage drop and the fundamental current and other parameters, the common-mode voltage filter is designed. The crosstalk coupling process between cable bundles is analyzed in this paper. Based on the finite element method, the distribution parameters of the cable bundle are analyzed and the structure of the cable bundle is optimized. With these methods, the impact of electromagnetic interference on the accuracy of remainders detection is reduced effectively.
