英文摘要： In order to guarantee the saftey, reliability and high efficiency of China high speed railway transportation, and to establish the electromagnetic compatibility (EMC) specification system suitable for the China high speed railway situations, the study of this project will focuse on the characteristics of the electromagnetic disturbance and its coupling depended on the speed and operation mode of the high speed mutiple units (EMU). A new quantified and grading electromagnetic inference algorithm for EMU will be put forward. Considering the real electromagnetic environment of China high speed rail, the electromagnetic interference limits and the anti-interference requirements for EMU will be setup. Furthermore, a new electromagnetic compatibility of EMU prognosis and evaluation meathod based on the statistics theory will be studied and a modulized simulation model of EMU will be built. This will be very useful to guide the optimizing design of new model EMU, and to breakout the key technology of the new EMU’s development and manufacturing, to improve our contry’s innovated development level in this area. At last, the high frequency characteristics of the earthing resistance device will be studied to solve the common problem of the existing model EMU’s earthing and to improve the EMU’s EMC performance.
