| Abstract: | A vibration measurement system used for bridge model test is introduced in this article. The regulation, pretreatment and sampling of the signals output by the piezoelectric accelerometer is done in this system, and the result is transmitted to the computer. At last, the dynamic performance is gained by using the mode analysis software. |
