摘要
基于流变应力恢复地应力测量方法,研制了一种单线圈电流型振弦式三向压力传感器。通过单向加载标定试验和三向加载标定试验,研究了传感器的重复性、线性度及压力传感面之间的自干扰特性。
According to the rheological stress recovery method for in situ stress measurement, a 3- dimensional vibrating wire pressure sensor with single coil is developed. Uniaxial and triaxial loading calibration test are carried out to investigate the repeatability,linearity and the interference characteristic among the sensor faces.
