| Abstract: | This paper introduces a virtual test system for magnesium alloys damping capacity based on ADVANTECH PCI-1711 DAQ card and LabVIEW,and its hardware allocation and software module designed under LabVIEW 7.1 are discussed in detail.With the sine signals produced with YB1631 power generator,the testing process of vibration attenuation and strain signal is simulated.The results show normal data acquisition,normal peak value,and correct computation. |
