液压支架应力检测电路设计

Hydraulic Support Stress Detection Circuit Design

分析了液压支架的受力情况,采用电阻式应变片作为传感器,设计了应力检测电路,对应力集中的部位进行检测。给出了电路的设计方案,并进行了参数计算。该电路的输出信号,可以接入液压支架控制系统或综采控制系统,能够预防预报支架断裂等严重事故,有推广价值。

Analyzes the stress of hydraulic support,uses resistance strain gauge as sensor,design stress detection circuit to detect the parts of stress concentration.Shows the design of the circuit,and calculates the parameters. The output of the circuit can access to hydraulic support control system or mechanized mining control system,it can forecast and prevent of stent fracture and other serious accidents,so has value to apply.
