A Novel Approach to Vibro-Acoustic Fault Diagnosis Using Intrinsic Multidimensional Gnome Entropy Analysis and a Convolutional Neural Network

Due to the complex practical working conditions, fault diagnosis is very challenging in rotary machinery. Rotary machinery is often used in places with a high temperature, strong corrosion, or where acceleration sensors are hard to install. Thus, acoustical signal processing beco...

Effects of Electronic Layout and Beam Design on High-Speed Dynamic Characteristics of FFF 3D Printers

High-speed Fused Filament Fabrication (FFF) printers are prone to nozzle vibration caused by moving-part inertia, frame flexibility, and modal coupling during high-acceleration motion, which can reduce deposition-trajectory stability. This study evaluates the dynamic adaptability...
