Research on multi-path quadratic convolutional neural network-based bearing fault diagnosis

Yingying Ji, Jun Yao Gao, Xing Shao, Cuixiang Wang

In real-world complex situations, high levels of noise from the surroundings and other component resonances frequently distort collected vibration signals, giving the collected data non-linear features. This research presents a multi-path quadratic convolutional neural network (MPQCNN) for bearing fault diagnosis in response …

Revealing the Microscopic Mechanism of Elementary Vortex Pinning in Superconductors

Chen Chen, Yue Liu, Yun Chen, Yining Hu et autres

Vortex pinning is a crucial factor that determines the critical current of practical superconductors and enables their diverse applications. However, the underlying mechanism of vortex pinning has long been elusive, lacking a clear microscopic explanation. Here, using high-resolution scanning tunneling microscopy, we …

Single-crystal growth and magnetic properties of quasi one-dimensional compounds CeFe 2 Ga 8 and SmFe 2 Ga 8

Xiaoqin Deng, Dayu Yan, Cuixiang Wang, Cuiwei Zhang et autres

$Ln{M}_{2}{T}_{8}$-family materials have been proposed to be heavy-fermion systems with quasi-one-dimensional structures. We synthesized single crystals of ${\mathrm{CeFe}}_{2}{\mathrm{Ga}}_{8}$ and ${\mathrm{SmFe}}_{2}{\mathrm{Ga}}_{8}$ and systematically investigated their structural and magnetic properties. Both ${\mathrm{CeFe}}_{2}{\mathrm{Ga}}_{8}$ and ${\mathrm{SmFe}}_{2}{\mathrm{Ga}}_{8}$ exhibit an incoherent Kondo interaction between the localized $4f$ electrons …

Discovery of a Magnetic Topological Semimetal Eu$_3$In$_2$As$_4$ with a Single Pair of Weyl Points

Ke Jun Jia, Jingyu Yao, Xiaobo He, Yupeng Li et autres

Magnetic Weyl semimetal (MWS) is a unique topological state with open surface Fermi arc states and other exotic transport phenomena. However, most reported MWSs show multiple pairs of Weyl points and complicated Fermi surfaces, which increases the difficulty of the investigation into …

Bearing fault diagnosis method based on improved deep residual Siamese neural network

Chen Qian, Jun Gao, Xing Shao, Cuixiang Wang et autres

Aiming to address the problem that faults in rolling bearings make effective fault diagnosis difficult under small-sample and varying working conditions, this paper proposes a new fault diagnosis method for rolling bearings that monitors their vibration signals and is based on an …
