Bending-torsion coupling vibrations of dual-disk rotor system with imbalance and oil film bearings

Advances in Mechanical Engineering
Due to the errors of manufacturing and installation of the rotor system, there is a certain deviation between the centroid and the geometric center of the rotor, known as eccentricity, which causes the bending and torsional vibrations during operation ...

Vestibular Evoked Myogenic Potentials to Diagnose Vestibular Neuritis: A Scoping Review

The Laryngoscope, EarlyView.
Standardization of stimulation and recording protocols is essential to improve comparability across VEMP studies. Integrating cervical and ocular VEMPs with other vestibular tests enhances diagnostic accuracy and supports precise localization of vestibular neuritis.

Sol‐Gel Coating on CA‐60 Steel Surfaces: A Process for Corrosion Inhibition

Materials and Corrosion, EarlyView.
30% of the steel produced worldwide is used to replace losses due to corrosion. The application of the sol‐gel process to inhibit and delay deterioration appears as a viable methodology for protection against aggressive environments. ABSTRACT The phenomenon of corrosion causes worldwide damage, which is not only economic but also results in the loss of

Molecular Dynamics Study of Melt Structure and Transport Properties of Mg‒Al Alloy

Materials Genome Engineering Advances, EarlyView.
The structural evolution and transport coefficients of the Mg‐Al alloy melt at different temperatures were investigated using molecular dynamics simulation methods. By establishing relationships among structure, diffusion, and viscosity, the microscopic mechanisms behind the temperature‐induced changes in transport properties are revealed. ABSTRACT The

Effect of Variations in the Ring Thickness on the Dynamic Performance of the Bimetal Gears

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study used a six‐degrees‐of‐freedom dynamic model to analyze the dynamic response of bimetal spur gears. Aluminum alloy forms the core of the bimetal gears, and a uniform‐thickness steel ring surrounds the teeth. Gear mesh stiffness of bimetal gears and the transmission error have been assessed using a numerical approach based on finite ...

Large Deformation Pile‐soil Interaction Under Lateral Vehicle Impact Using Hybrid SPH+FEM and EFG+FEM Models

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT This study presents large deformation computational methods to simulate lateral vehicular impacts on steel piles in granular soil. Soil‐mounted longitudinal barrier systems rely on energy dissipation in both the piles and the surrounding soil to safely redirect errant vehicles, so dynamic pile‐soil interaction is important for design ...
