电阻式测力锚杆实时监测技术研究

Study on the Real-time Monitoring Technology of Resistive Dynamometry Bolt

在测力锚杆现有研究基础上,对电阻式测力锚杆轴向力和弯曲角度实时监测技术进行研究。结果表明,采用电阻应变片作为测力锚杆轴向力传感器,三轴加速度传感器作为测力锚杆弯曲角度传感器,可以测量测力锚杆轴向力和弯曲角度。

On the basis of the existing research on the dynamometry bolt, this paper studied the real-time monitoring technology of axial force and bending angle of resistive dynamometry bolt. The results showed that taking electric resistance strain gauge as the axial force sensor of dynamometry bolt and taking three-axis acceleration sensor as bending angle sensor of dynamometry bolt can measure the axial force and bending angle of dynamometry bolt.
