涡流检波器特性测量与参数识别

新型涡流检波器已在地质、石油、煤炭人工地震勘探中采用。本文将最新的振动试验方法、数据处理技术及模态参数识别应用到检波器特性参数的确定中。论述它的有效优化方法,并首次将它应用到传感器的标定技术中,做到快速准确测定它的参数值,为检波器的生产、使用提供技术保证,亦为涡流检波器参数综合测试仪研制提供理论基础。

Eddy-Seis Characteristic Measurement and Parameter Identification

The Fdddy-Seis, a unique new type of geophone, has been adopted by artificial seism in geologic survey, oil and coal exploration. This paper applies the new vibration test methods,data processing techniques and modal identification approach to eigen-parameters of geophones test, discusses its efficient optimizing technique, and first applies it to demarcating technique for transducer, so that we can test lastly and accurately the eigen-parameters of geophones. It will offer assurance in technique for the producing and use of the geophone, and provide theoretical basis for developing the Eddy-Seis comprehensive tester.
