【Abstract】 Based on sound card hardware,LabVIEW and Python software environments,the dynamic method for measuring elasticity modulus was established.The virtual signal generator on LabVIEW platform and the Recorder audio acquisition program of the operating system were applied to replace the signal generator and oscilloscope adopted in traditional dynamic method,and a Python program was utilized to analyze the audio frequency to get the resonance frequency of the sample material,and then to calculate its elasticity modulus.更多还原
