Over the last 20 years， mainly due to the vibration caused by the fatal accidents occurred one after another， inflicting huge economic Furthermore， the vibration is still new to large units shipped impossible grid， the normal operation for the main the crew during normal operations， continuous vibration problems affecting the normal production， Units often reduced load and operation of the sick， and even the unit was forced to stand， these incidents not The system based on LabVIEW virtual instrument software platform for turbine vibration signal window read， and spectral analysis and correlation LabVIEW virtual instrument is a common core of computer hardware platform， defined by the user， with virtual front panel， the test function test software from a computer equipment The system completed the turbine vibration signal read， the signal rectangular window Hanning， Hamming window window choice， and then the signal amplitude spectrum， power spectrum and phase spectrum analysis and correlation analysis， and operating with graphics and display The result of running the system proved that the system can accomplish the signal read， and three window function and the dynamic analysis of the various options and graphical display with the
