中文摘要：

为实现采煤机滚筒扭矩的实时精确检测,提出了一种基于压电振动俘能装置自给供电的滚筒扭矩检测系统。压电振动俘能装置将采煤机工作过程中Y、Z方向上产生的振动能量有效地转换为电能,实现对检测系统无线应变采集模块和销轴传感器的长期、稳定供电,避免了电池更换需要反复拆卸的难题。现场实验测试表明,扭矩检测系统自供电性能稳定,系统能够实现采煤机滚筒Y、Z方向上所受载荷的实时、精确检测,从而准确推算出滚筒的扭矩,系统具有较高的检验精度和可靠性。

英文摘要：

In order to achieve real-time shearer roller torque detection precision,this paper proposed a self-powered detection system based on piezoelectric vibration energy harvesting device.The vibration energy produced by the shearer in the working processes of Yand Zdirections would be converted into electrical energy effectively,which ensured the long-term effectiveness working of the pin shaft sensor and wireless strain collection moduler and avoided the problems of power-supply module which needed replacement and repeated disassembly.The results of the experiments show that the self？powered performance of testing system is stable,the load of the shearer roller in the Yand Z directions may be detected precisely in real time,the roller torques are calculated,and indicates that the system has higher accuracy and reliability.
