振动台模型试验中的相对位移测量

Displacement measurement of modle experiment in shaking table

针对大型振动台模型试验中存在的位移测量问题,采用光学非接触测量的方法设计了一种相对位移传感器,其准确度为10μm,频率响应为0～100Hz。并在某管道跨越工程地震模拟振动台试验中与其它传感器相比对,实验验证结果表明:该传感器的主要技术指标完全满足设计要求。

Considering of displacement measurement for structure in shaking table,noncontact optical method is used to develop a sensor,its accuracy is 10 μm and the frequence response is 0～100 Hz. In the earthquake simulation test for a river-across pipe,compared with other sensor,it is verifed by experiment that the sensor' main technology index can meet the design demand.
