| 摘 要： | 为了更有效地进行煤岩界面识别,利用扭振信号来进行煤岩界面识别研究。首先从理论上分析了扭振信号与滚筒截割力的关系;应用小波包和模糊神经网络技术进行信息特征提取和数据融合,论证了扭振信号的有效性与可靠性,并与直线振动信号进行了对比。识别结果表明,扭振信号数据比较稳定,识别正确率达到92%;而直线振动信号的正确识别率为63%,理论分析与试验验证是一致的。通过滚筒轴扭振信号来监测采煤机运行状态是一有效手段。

| Abstract: | The study on the effective coal-rock interface recognition(CIR) was carriedout by torsional vibration signal.The relationship between the torsional vibration signal and drum cutting force was analyzed theoretically.Through carrying out feature selection and data fusion by the wavelet packet and fuzzy neural network technique,the availability and reliability of torsional vibration signal were verified and compored with those of vibration signal.The recognition results show that the torsional vibration signal... |
