Uncertainty Quantification for Nonlinear Vibration of Supercritical Drive Shaft With a Dry Friction Damper

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The supercritical drive shaft is becoming increasingly popular in helicopter transmission system. Dry friction dampers are specially employed to ensure the supercritical shafts crossing the critical speed safely. Due to design tolerances, manufacturing errors and time‐varying factors, the parameters of the damper are inherently uncertain ...

Elucidating the Three‐Dimensional Structure of Piracetam through Rotational Spectroscopy

ChemistryOpen, EarlyView.
Neutral molecules of the nootropic drug piracetam are generated by laser ablation and structurally characterized by microwave spectroscopy. Two conformers differing in the exo/endo configuration of the pyrrolidine ring are detected, with exo being the predominant form.

Quantifying Molecular Properties of Hexagonal Water Clusters

ChemistryOpen, EarlyView.
Standard quantum chemical calculations on large hexagonal water clusters allow us to analyze the fundamental properties of ice‐Ih. Computed geometrical structure, energies, and vibrational spectra are astonishingly close to experimental data without the introduction of any external empirical parameters.

Impact of basalt powder on the rheological, thermal, mechanical, and tribological properties of natural and polychloroprene rubber composites: A study on aging and filler interaction

Polymer Composites, EarlyView.
Impact of basalt powder on the rheological, thermal, mechanical, and tribological properties of natural and polychloroprene rubber composites. Abstract This study investigates the effects of basalt powder (BP) as a filler in natural rubber (NR) and synthetic polychloroprene rubber (CR) composites, focusing on their structural, mechanical, and thermal ...
