摘要：
To precisely analyze the electromagnetic environment in automotive engine block radiated by High Electromagnetic Pulse (HEMP), the complex metallic equipments with different shapes at different positions, such as radiator, engine and gear-box were considered. The electric fields were computed at more than 500 points in the block, and the results were verified using self-reference method. Finally, the electromagnetic environment was analyzed from views of the electric field distribution, the frequency of occurrence of peak value and the electric field resonances. The results show that the electric peak values are Rayleigh distributed. The radiator leads the shift of the resonance frequency, and the engine results in the increase in electric field in important region. Metallic equipments evidently impact on the maximum electric field peak values in the block, which is doubled. © 2016, Editorial Board of Jilin University. All right reserved.
