[Abstract]:With the rapid development of information technology in modern society, electromagnetic interference (EMI) becomes ubiquitous, and the electromagnetic sensitivity of all kinds of equipments in aircraft systems is becoming higher and higher with the application of various kinds of electrical and electronic equipment. More and more attention has been paid to its electromagnetic compatibility. EMC capability of airborne equipment plays an important role in aircraft design, production and safety. This paper focuses on the crosstalk of cable harness of airborne equipment, sensitivity analysis of cable harness and electromagnetic compatibility experiment of airborne equipment. The main contents of this paper are as follows: firstly, the related theories of EMI and EMC are introduced, including the theory of complex electromagnetic environment, the composition of EMI model, the electromagnetic environment of aircraft and the effect analysis. Secondly, the conduction interference and radiation interference of cable harness of airborne equipment are studied. The calculation method and model of crosstalk value and electromagnetic sensitivity of cable harness are analyzed, the specific experimental environment of aircraft is analyzed and the model of aircraft and interference wave under special experimental environment is established. The crosstalk of six kinds of cable harness and the electromagnetic sensitivity of six kinds of cable harness are calculated by the means of software simulation, and the calculation results are analyzed. Finally, taking gyroscope as the object of study, according to the method of CE102,CS101,RE102 test item in GJB-152A-97 "electromagnetic Emission and sensitivity Measurement of military equipment and Sub-system", we have made the corresponding test plan, and carried on the actual test experiment to it. The experimental results are analyzed.
