摘      要：The manifold physical signals including micro resistance,infrared thermal signal and acoustic emission signal in the tensile test for double-material friction welding normative samples were monitored and collected dynamically by TH2512 micro resistance measuring apparatus,flir infrared thermal camera and acoustic emission equipment which possesses 18 bit PCI-2 data acquisition *** acoustic emission and thermal infrared NDT(non-destructive testing) means were used to verify the feasibility of using resistance method and to monitor dynamic damage of the *** research of the dynamic monitoring system was carried out with multi-information fusion including resistance,infrared and acoustic *** results show that the resistance signal,infrared signal and acoustic emission signal collected synchronously in the injury process of samples have a good ***,thermal and acoustic signals can more accurately capture initiation and development of micro-defects in the *** dynamic micro-resistance method to monitor damage is *** method of multi-information fusion monitoring damage possesses higher reliability,which makes the establishing of health condition diagnosing and early warning platform with multiple physical information monitoring possible.
