Abstract Spatial variations in stiffness and mass density make the free-vibration behavior of tridirectionally functionally graded material (3D-FGM) beams highly sensitive to material gradation, while computationally eff...

Dual-drive feed systems are widely adopted in high-end CNC machines because of their high precision, rigidity, and operational stability. Vibration suppression during machining is critical to maintaining feed accuracy an...

ABSTRACT Strength and conditioning professionals continuously seek innovative strategies to enhance neuromuscular performance. This study examined muscle activation in the rectus femoris (RF), vastus lateralis (VL), vast...

Abstract The vortex-induced vibration (VIV) characteristics of a long-span twin continuous steel box girder bridge under varying wind angles of attack (α m ), Scruton numbers (Sc), heights of beam (D = 0.078 m, 0.108 m,...

Power transformers are critical components of power systems, and their safe and reliable operation is essential for both industrial and residential applications. Real-time condition monitoring and early fault detection a...

ObjectiveRescue drilling rigs undergo intense vibration at borehole mouths when operating in a confined underground space of coal mines. To address this issue, this study designed a compact multi-directional, passive dyn...

When using the blasting caving method to treat goaf, the collapsing ore and rock can cause shock disturbances to the roof of the lower stope, which may lead to stability risks. This study takes the goaf treatment project...

In recent years, the study of the static and dynamic mechanical behavior of porous functionally graded material (PFGM) structures has attracted much interest. However, most of the existing studies analyze their static or...

Abstract The shift from internal combustion engines to electric powertrains has redefined the noise, vibration, and harshness (NVH) profile of contemporary vehicles. The reduction of engine-generated broadband noise has ...

We present an experimental investigation of the pressure dynamics during the flow of self-propelledparticles through narrow passages. When the ensemble is flowing, pressure fluctuates around aconstant value that does not...

Nonlinear response conception in rotating machinery, particularly in systems with squeeze film dampers (SFDs), pose significant challenges for established time-domain numerical methods due to bifurcations and critical po...

The laminar shear box is the most commonly used soil container in shaking table tests for soil-structure dynamic interaction. On the basis of the development experience of the worldwide shear boxes, the two-dimensional l...

Abstract The emergence of phonon frequency combs exemplifies a rare and intriguing phenomenon in quantum solids. Materials with distinctive phonon band structures are especially promising for hosting such states, as thei...

Accurate melting point prediction for nitro-containing flexible organic molecules is critical for optimizing their performance in pharmaceuticals, energetic materials, and chemical processing. Using nine representative n...
