DP传感器研究及桥梁自振特性测试

Research on DP Transducer and Its Application in Measurement of Self Vibration Characteristics of Railway Bridge

研究了磁电传感器的动态特性补偿方法，开发出具有高机械稳定性和低固有频率的ＤＰ传感器，并利用ＤＰ传感器对铁路桥梁的自振特性进行了测试。实验表明了该传感器的有效性。

This paper presents a compensation method for seismic velocity transducers, and besed on this method develops a DP transducer which has a high mechanical stability and low natural frequency. The DP transducer is used in measuring the self vibration characteristics of a railway bridge, which proves to be an effective method.
