In order to improve the experiments of vibration engineering testing

reform teaching methods and to improve experimental results

a set of LabVIEW-based beam vibration signal testing and analysis system is developed.Lower computer uses C8051F350 MCU which has extensive on-chip resources and higher data processing capacity to collect vibration data.And communicates with host computer by RS—232 serial to transmit the signal data.Host computer software exploitation based on the LabVIEW development platform which had powerful graphical programming dummy instrument to complete data and real-time display

and carried it on time domain and frequency domain analysis and data storage functions.The practical application shows that the system is stable

reliable and meet the test requirements.The LabVIEW applied to the experimental teaching greatly increases the interest of students and improves the experimental results and teaching quality.
