| Abstract: | AFDX is currently internationally recognized as the mainstream airborne network of transport aircraft. AFDX, as the main network of avionics, connects a lot of AFDX network equipment. Therefore, the EMC of these airborne equipment is particularly important. In this paper, based on the actual engineering experience, for AFDX network equipment, analyzes the EMC influence of the clock circuit, interface circuit, mechanical structure and cables. In addition, the practical design method and typical application examples are proposed. |
