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...

Abstract In previous studies about the synchronization of vibrators, the restoring forces of springs are mainly treated as linear directly, whereas the nonlinear features are rarely considered in vibrating systems. To ma...

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 With the further development of service-oriented, performance-based contracting (PBC) has been widely adopted in industry and manufacturing. However, maintenance optimization problems under PBC have not received...

Abstract The new energy vehicle plays a crucial role in green transportation, and the energy management strategy of hybrid power systems is essential for ensuring energy-efficient driving. This paper presents a state-of-...

Abstract Currently, a 2-port microwave transmission line with a glass window is usually used to transmit microwave energy to a pressure vessel while sealing the high-pressure gas. In this situation, the damage of the bri...

As a novel reactive damage material, high-entropy alloys (HEAs) have garnered widespread attention in the field of reactive damage in recent years due to their excellent mechanical properties and favorable energy release...

Biologic therapeutics have transformed the treatment of chronic and life-threatening diseases, yet their clinical use depends almost entirely on parenteral administration. Oral delivery is the preferred route for patient...

Bobbin tool friction stir welding (BT-FSW) is a solid-state joining technique that produces high-strength welds without the need for backing plates. This study introduces a new variant, termed hybrid bobbin tool friction...
