| People have done much research work about vibration and noise ofvehicle for a long time, but there is another important automotivecharacteristic-electromagnetic compatibility been ignored. This paperdiscussed the electromagnetic compatible environment of vehicle including thetypes of wirings in vehicle and the forms of electromagnetic interfere. Throughthis analysis, a conclusion can be draw that this interferes can greatly affect theequipment’s normal behave and the electromagnetic compatible environment iscomplex.In order to probe into the detail information of the electromagneticenvironment of vehicle, an auto-electric test-bed system made up ofequipments of Transit vehicle has been made and it has most wirings of Transitvehicle. To find out electromagnetic compatible information of the auto-electrictest-bed system, a detect system has been exploited. And the results of thedetecting show that there are serious electromagnetic interferences in theauto-electric test-bed system, especially the interferences coursed by ignitionare more dangerous than the other interferences.The following is the main work of the study.(1) Analyze the principle and the performance of the main interferes invehicle andthe effect to the wires of the vehicle caused by it(2) An auto-electric test-bed system has been made based on the theoryanalyses(3) Put forward the ways of bating the electromagnetic interferences andthe idea of adopted parallel thinking to design the electromagneticcompatibility... |
