Abstract:Quantitative testing principle of cracks defect on steels based on virtual instruments is presented.Quantitative testing system for crack defect on steels surface based on Virtual instruments is designed The approach on realizing data acquistion and data analysis based on LabVIEW is analyzed in detail,and simulation experiments are done Mathematical model is built The Quantitative testing result to reflect on condition of crack can be acquired by Quantitative analysis the signal peak-peak value.Experiment results has proved the feasibility and effectiveness of the method, and relative conclusion is obtained.
Keywords:Quantitative testing  Virtual instruments  LabVIEW  Data Acquisition
