| Abstract: | Based on the research of vibrating wire sensors working principle,this paper built a structural strain signal dynamic collecting system of vibrating wire transducers,and made a contrasting experiment between this system and an authentic signal testing equipment-DH（5923_1394）,the testing object of which was cantilever beam.Besides,by analyzing the dependence of the collecting results with Matlab,the article proved the feasibility of vibrating wire transducers in constructural strain dynamic testing,and made theorial and experimental foundation for the application of vibrating wire sensors in dynamic structural strain testing. |
