| 中文摘要: |
| 本论文介绍了一种负压气力输送系统在水泥库清库作业上的应用，通过负压气力输送原理将水泥库库内较小颗粒物料输送至水泥库外，对于较大较硬结块配合破碎取料装置，将其破碎扬起流化后强制送进负压气力输送管道，实现对水泥库内物料的无人化、密闭化清理，该方案充分解决了水泥库库底物料难以在无人入库情况下进行清理，从而充分保障作业人员生命安全，解决无法完全实现无人入库清理作业的难题。 |
| 英文摘要: |
| The health of rolling bearings is related to the normal operation of rotating machinery, predicting the remaining useful life of bearings is a key method to avoid the failure of bearings and their systems. Aiming at the problem that traditional bearing life prediction methods cannot adjust the feature weight adaptively and extract useful features, resulting in large error of predicted values, dynamic residual network with convolution block attention module (CBAM) was proposed to predict bearing remaining useful life (RUL). Firstly, the cumulative amplitude in frequency domain is obtained by fast. |
