摘　　要：信息车辆具有系统构成复杂的特点,其电磁兼容性能可通过测试掌握,但其在投入使用后,其电磁兼容性能信息便无法准确获取。由于因维护保养程度的不同,整车电磁兼容性能显著下降而导致整车效能下降的实际情况大量存在,因此需要通过研究一种针对全寿命期的电磁兼容性能快速评估技术,针对已投入使用的信息车辆,设计易于实施的快速测试方法。根据测试结果,找出对车辆关键性能有较大影响的缺陷,并定位故障点,实现精确维修保障。The information vehicle is a complicate system. Its Electro-Magnetic Compatibility(EMC)can be obtained by measuring. However,after being put into use,the EMC performance cannot be accurately obtained anymore. Due to the different circumstance of using and maintaining,the whole vehicle performance significantly decrease because of decline in the EMC are widely existed. Thus,there is a need to study a fast evaluation technology for EMC performance of in-service information vehicle in its total life cycle,which is easy to implement. According to the evaluation result,the fault points which cause great impact on the critical performance of whole information vehicle can be found and located,and then the accurate maintenance can be achieved.
