摘要
介绍了一套用于桥梁模型试验的振动测试系统。该系统完成了压电式加速度传感器输出信号的调理、预处理和采样,并实时传送至计算机对信号存贮和处理。然后,利用模态分析软件得到了模型结构的自振特性参数。
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.
