Abstract The remaining useful life (RUL) prediction of mechanical products has been widely studied for online system performance reliability, device remanufacturing, and product safety (safety awareness and safety improv...

In the present study, the transmission error (TE) behaviour of an identical involute spur gear pair dynamically coupled with an attached subsystem is investigated through numerical modelling. The surrounding mechanical s...

Abstract In recent years, there has been a surge of interest in air-ground collaborative robotics technologies. Our research group designs a novel combination-separation air-ground robot (CSAGR), which exhibits rapid aut...

Abstract At present, the active control of gear vibration mostly relies on existing algorithms. In order to achieve effective vibration reduction of the gear system, particularly during the vibration process, this paper ...

Hydrogen is widely recognized as a clean and sustainable energy carrier, driving the urgent need for safe and efficient solid-state storage materials. In this study, the structural, thermodynamic, electronic, optical, an...

Upconversion photodynamic therapy (UC-PDT), which integrates upconversion nanoparticles (UCNPs) with photosensitizers (PSs), presents a promising advancement in the field of phototherapy. However, despite the extensive s...

Introduction. Self-excited induction generators (SEIGs) play a vital role in renewable energy systems, particularly in remote regions. However, their performance is highly sensitive to excitation capacitance, rotor speed...

Abstract Current research on the dynamics and vibrations of geared rotor systems primarily focuses on deterministic models. However, uncertainties inevitably exist in the gear system, which cause uncertainties in system ...

The integration of ultrasonic energy into polymer melt processing enables control of melt-state dynamics and microstructure evolution in thermoplastic systems. By superimposing high-frequency mechanical vibrations onto c...
