摘要:
滚筒的损坏会导致皮带倾斜，严重时会导致皮带撕裂，准确检测滚筒的损伤程度能够避免事故发生，并能够提高经济效益。选择带式输送机的滚筒材料作为研究对象，模拟滚筒所处的温度变化环境，对不同损坏程度的滚筒材料进行环境模拟并测试，通过传感器采集频率响应信号，通过主成分分析、异常值分析和微量组分分析方法，只改变温度数据滚筒材料马氏平方距离值相对平缓，控制在0.06×104，真正损坏的马氏平方距离值远远大于临界值，成功去除温度变化对材料频率响应信号的影响，最终找到了能够准确检测滚筒材料的损伤程度的方法。
Abstract:
The breakdown of roller can lead to the lean of belt, when seriously, it will cause the tearing of belt. Detecting the damage degree of roller accurately can avoid the accidents and improve the economic benefit. Choosing the roller material of belt conveyor as the research object, the environment of temperature variation in which the roller existed was simulated. The environmental simulation and test were conducted on roller material with different damage degree. The frequency response signal was acquired by sensor, through combining the principal component analysis, outlier analysis and the miner component analysis method, only changing the temperature data, the Markov square distance of roller material was relatively flat, which was controlled within 0.06×104, and the Markov square distance of real damage was much larger than the critical value. The influence of temperature variation on the frequency response signal of material was eliminated successfully, and eventually the method being able to accurately detect the damage degree of roller material was obtained.
