Abstract：

Based　on　the　electromechanical　impedance　and　ultrasonic　guided　waves　technologies,　the　location　of　damage　in　the　composite　beam　was　achieved　by　combining　the　data　fusion　arithmetic.　Firstly,　using　respective　characteristics　of　damage　monitoring　of　the　two　methods,　a　kind　of　arithmetic　called　synthesized　damage　index　was　proposed　to　represent　variations　of　tested　structure.　Location　of　damages　in　large　region　could　be　achieved　with　the　two　methods　respectively.　However　the　result　was　not　accurate　enough.　Finally,　the　synthesized　damage　index　was　used　to　represent　damages.　The　result　shows　that　the　location　of　damages　can　be　recognized　accurately　with　the　synthesized　damage　index　which　is　achieved　by　using　data　fusion.　The　damage　location　assessment　is　achieved.　©　2015,　Beijing　University　of　Technology.　All　right　reserved.
