| Abstract: | A real-time data acquisition system based on IBM-PC for vibration test is provided. The highest sampling frequency of each channel is 100kc/s. There are 16 A/D channels and 2 D/A channels in this system. The tests of frequency spectrum analysis and vibration stress distribution of blade have been completed with this system. |
